xdg-open tries to determine the desktop enviroment you are running and
uses its way to open files...
If you are in a kde session, it will just run kfmclient XXX (kde way to
open files in their application), for gnome it will use gnome-open or
something...

So even if you are not logged in a "full" gnome or kde session, but have
some of its packages installed, you can "trick" xdg-open to use that
enviroment
for kde just export KDE_FULL_SESSION=true,
for gnome GNOME_DESKTOP_SESSION_ID=something

so you can run beagle-search with
GNOME_DESKTOP_SESSION_ID=something beagle-search

you have to  set which applications to use in corresponding config
(for kde, just run konqueror/dolphin and right click a file, don't know
for gnome)

for kde, you need the package kde-base/kfmclient, which should depend
juast on kdelibs, for gnome-open you need gnome-base/libgnome, which
shouldn't have much dependences that you don't have allready if you have
some gtk app..

btw, gnome-open/kfcmclient will open files in any available program that
correctly registers its mime-types, not only in kde/gnome apps..., so
you really need only kfmclient/libnome to use it...


one last remark, if set KDE_FULL_SESSION/GNOME_DESKTOP_SESSION_ID for
xdg-open and it starts a gnome/kde app, that app might think that there
are some desktop specific things running, that are not, though I haven't
seen any real problems with it...
You might however just edit the "detectDE" function in xdg-open to
always behave like gnome/kde without settings the variables...

yoyo


PS the idea of xdg-open using a browser, when it cannont detect which DE
are you running, is that a browser usually knows how to open which
files... and you should have your preffered browser set in $BROWSER...

Hi,
  I just had to restart my computer (power issues :( ) in the middle of
an update (well, it was more like 'just before the end';) and after
restart I have the same problem as you, no /dev/sd[ab]* files...

My first guess was that I rebooted without updating the config files, so
I ran etc-update (there were some udev config files as well as init
script) and rebooted, but that didn't help.

It is certainly not a problem with drivers not being in kernel, as the
kernel sees the disks and partitions (see below), so I just run

tail  -n +3 /proc/partitions | while read maj min size name  ; do  mknod 
/dev/$name b $maj $min ;  done
/etc/init.d/localmount pause; /etc/init.d/localmount start

to get everything mounted again...

That means it will have to be an  udev (or even openrc) problem.
The last update of udev did in fact say this:

 * Checking for suitable kernel configuration options...
 *   CONFIG_SYSFS_DEPRECATED:should not be set. But it is.
 *   CONFIG_SYSFS_DEPRECATED_V2: should not be set. But it is.
 *   CONFIG_IDE: should not be set. But it is.
 * Please check to make sure these options are set correctly.
 * Failure to do so may cause unexpected problems.
 * 
 * udev-151 does not support Linux kernel before version 2.6.25!
 * For a reliable udev, use at least kernel 2.6.27

 * Your kernel version (2.6.28-gentoo-r2) is new enough to run udev-151 
reliably.

I didn't want to mess with the kernel right now, but I gues that's the
first thing to try...
I'll report when I rebuild & reboot...

yop, that was it

though you wrote about /dev/hda*, which means you should be a bit more
carefull if you used the IDE drivers (under ATA/ATAPI/ support,
thats the "CONFIG_IDE" option) and disabled the CONFIG_IDE options, you
have to enable it under
Serial ATA (prod) and Parallel ATA (experimental) drivers (CONFIG_ATA)
and also your device might get renamed to sd* instead of hd* (I don't
know, I have only a cdrom, that becomes sr0 ;)

But I think that the real problem was with those SYSFS_DEPRECATED
options, so you might be able to get things working with just disabling
those and leaving IDE as it was...

btw, I found this bug afterwards:

Btw you can fire up add applets on the desktop and drag them to a

Panel and desktop settings are in .kde/share/config/plasma* files
removing just them (ideally when logged out of kde) should bring the
default desktop/panels back..

theoretically plasma-desktop-appletsrc should be enough to delete...


Don't see how different from kde3 this is.. if you messed up your
kicker configuration you had to either delete it, or rebuild the panel
(create it, place it at the correct position, add correct applets...)
(well, the only difference is that desktop and panel were separate
programs...)

don't know about alternatives, but gnome-mplayer with -gnome use flag
(and the same holds for gecko-mplayer) is just a "simple" gtk app,
just like firefox itself, nothig gnome specific about it and
theoretically it can look better in firefox than qt apps, because they
both use the same engine/theme ;)

with -gnome it also doesn't bring in any gnome dependencies... its just
that it is named gnome-... (well, because when you enable it, it can
becamu a "full" gnome app..., though I really don't know what gnome
features it uses ;)

I think taht KDE4 do not touch your initial keyboard settings (xorg.conf or
hal,...) unless  you change something in its keyboard config
(systemsettings ->regional&language->keyboard layout )
maybe that you have wrong keyboard set explicitly there?

I have "disable keyboard layouts" under the "layout" tab selected,
but I can't say if it really works correctly (keeps the X
configuration defaults) right now, because I can't restart X right now,
and I change between
'setxkbmap -option grp:shifts_toggle sk,us qwerty,'
and a simple 
'setxkbmap us'
with some scripts, because the dual layout confuses some apps like
synergy, x2x, rdesktop, even some vnc clients... 


what happens if you you type "setxkbmap de" in an terminal (konsole,
xterm,...) after kde starts up?

You can still break the emerge (for example with ctrl-c) when it starts
to emerge gcc, the continue the emerge process with  emerge --resume --skipfirst

You can do something like:

emerge -pe world | sed -e "/^.ebuild/ ! d; s/.*] /=/; s/ .*//; " > list

... edit "list" and remove anything you don't want to reinstall ...

emerge -av1 `cat list`

the -1 (or  --oneshot), means that the packages won't be added to the world
file (they would normally because you are listing them all on the
commandline)

yes, it knows what the last emerge was, so you just say --resume
but if you do another emerge in between, it will forget the previous 
interrupted one

--resume just "resumes" the last interrupted (or failed) emerge , starting with 
the package that was interrupted,
so that you can fix the problem if it was a compilation failure, and then 
continue... no need to give
any special args to the first emerge.

--skipfirst makes it skip the first  package - the one that was interrupted
handy when the emerge fails on a packages that isn't a depency of something 
other, you can just skip it then,
very much like  a "manual"  --keep-going ;)

you can break it whenever you want.. --resume than starts the package
again from beginning so you  just "waste" the time/work it allready did... 
which does not really matter if you are going to do  --skipfirst ;)

Works here (either in xorg.conf or in fdi files if let X use hal).
If you set up a keyboard layout in kde / gnome, it may be possible that
it resets the xkb options... though you seem to have the layout set in
xorg.conf, so that it seem improbable that you use the gnome/kde
layout configuration...

lxde-base/lxappearance

x11-themes/gtk-theme-switch

the last one allows one to specify the theme on commandline...
but you don't have to run them all the time like
gnome-settings-daemon... just run them once, select your theme and they
will set up your ~/.gtkrc-2.0 so that all gtk apps will use that
theme from now on... (unless you start up gnome-settings-daemon which
will enforce the theme selected in gnome settings... don't know why they
did it that way...)

If you are doing it this way (on a running system with mounted
dev/proc/sys...), you can just bind-mount your current / to another
directory. That "copy" will not contain any "sub-mounts" (as if you
accessed it from a livecd), so you could just do

(mount your /mnt/new_root)
mkdir /mnt/current_root
mount -o bind / /mnt/current_root
rsync -aHAX /mnt/current_root/ /mnt/new_root/

i always remout / readonly first, for that you usually have to go to
single user, or stop most of the services and programs...

yes, but it will miss any files "hidden" under those mounts, though

don't know about samba, but with scp or nfs I can get about 20MByte/s which is
the speed of my disk (and for scp almost what my cpu can manage ;)
scp-ing /dev/zero gets me something short of 30MBye/s but that is
because my CPU cannot manage more ;)

You can see an estimate of your "raw" speed between the two machines by
running 
nc -l -p  | pv >/dev/null
on one computer and 
pv /dev/zero | nc OTHER_COMPUTER 
on the other. I don't have a 1gbit  switch here right now, so can't give
you an estimate (with two notebooks connected directly by cable I just
got 100MByte/s, which is near enough to the theoretical maximum ;)
(pv is like cat, but displays a progressbar with act. speed, sys-apps/pv)

you can also try netperf for more precise benchmarks

hmm, that seems a bit low even for 100mbit, I have usually no problem getting
cca 10 MByte/s with 100mbit switches (without other traffic), though I
use either nfs or scp
the only time I remember using samba was with a winxp server, which
didn't go above 1MB/s, but I suspect that the problem was either on the
win side or some misunderstanding between win and linux ;)

from time to time I tried to use the commandline options of
nvidia-settings to change between two sets of outputs (main+tv and
main+second monitor) but it seems, that nvidia-settings just can't
enable/disable outputs from commandline ... it wasn't very important for
me, so I didn't ask on any more nvidia specific forums...

but your mail made me look at the sorces of nvidia-settings, and there's
a "samples" directory with some examples, and it seems that nv-control-dpy can 
do that...
you should be able to enable the correct outputs with --set-associated-dpys and 
then 
load your configs as you tried... (I didn't try that, just checked in
the gui that the output changed to "off" insteadd of "disabled")

maybe it is even enough to run the --probe-dpys according to what you say about 
selecting
"detect displays" in the gui...

why should it handle USE flags in any way?
it just tels portage not to emerge the dependencie, whatever they are (
when added by use flags..)

that means
USE="alsa" emerge --nodeps mplayer
would (try to) compile mplayer _with_ alsa support
but in the case alsa-lib (which is an optional dep on the alsa use flag)
 is no installed, it will not emerge it
(which can cause mplayer not to compile, or not to work...)

cookie is certainly your's, bootsplash-themes do depend on bootsplash,
i was just just wondering about your comment, that they can't be used
with fbsplash..
but you were right too ;))), just remembered that i did a
bootsplash2fbsplash on my themes (or changed the few things in which
they differ by hand ;)

I usualy do:

as someone other said, you should setup NAT, there should be enough
information on the wiki, but basically
iptabales -t nat -A POSTROUTING -o eth0 -s 192.168.2.0/24 -j MASQUERADE
on PC1 should do it, but there might be better ways ;)
(note that you need some iptables stuff in the kernel)

one other thing, if nat doesn't work, some wireless aps (i'm thinking
about the 192.168.2.1) need to have correctly set up default gateway
etc... they sometimes try to be to smart and I had sometimes problems
when the router was connected as a wireless client to them...

btw, why don't you use the wireless on the ROUTER1 (doesn't seem you
want to do any firewalling on the PC1)? It might make things much
simpler... you could setup the other ap to connect to it in client mode
and all your network could then be on the 192.168.1.0/24 and I would
gues that your provider NATs the whole subnet...

Mozilla-firefox does have a startup-notification use flag, do you have

Well, kde doesn't know that you are starting an app, so there's no

look at the rc_hotplug option in /etc/rc.conf
something like rc_hotplug="!net.eth0" should work for you...

the other option is, if you emerge ifplugd, the net.eth0 service will
use ifplugd to see if there is a cable connected... it will start but
will not set up the interface until you plug in a cable...

It just needs a relogin to show the option in the logout dialog, last time I 
tried it, it worked this way:

 - switch to restore manually saved session in  systemsettings/wherever,
   no "save this session" appears in the logout dialog...

Now that I looked at it, it really isn't in the logout dialog, but it is
in the "Leave" tab in the start menu:

emerge -av x11-misc/xautomation
xte --help

it allows you to move mouse, click, send keypresses...
finding the right coordinates to click might not be easy (although the
package contains som programs that allow you to find specific pictures
on screen...) but sending the correct  tab and enter sequence should be
enough (I expect just pressing enter in the dialog should be enough)

you should be able to use this also with firefox
send alt-f, p, few tabs to get to the "print to file", space, enter,
name of the file, enter
;))

Just to make sure, is the app you're trying to run 32bit or 64bit?
If its 32bit, you would need some of the emul-linux-x86 packages,
perhaps  app-emulation/emul-linux-x86-qtlibs to get the 32bit libqt-mt..

You probably haven't emerged the applications with Xinerama support.
This is especially true for kde 3. Twinview uses the xinerama protocol
(well,its an extension of the X protocol... ;) to inform applications
about the layout of monitors.

As I said, twinview uses the xinerama protocol to inform apps about the
monitors, so there wouldn't be any difference in the way applications
behave.  You would only loose the  advantages of twinview (you can look
at it as an enhanced, nvidia only, in-driver version of xinerama)

Even xrandr 1.2 provides xinerama style info for the applications, so
you certainly want your application to be compiled with xinerama
support, independently of the way you set up the X server.

BTW in my experince kde compiled without xinerama supp. handles multiple
(independent) screens O, but not xinerama (well, that could be
expected), and with xinerama support it handles xinerama ok, but fails
with independent screen ;)

Re: [gentoo-user] Xinerama vs TwinView for dual monitor setup

[YoYo siska]

ne is flawed. Which bit did I get wrong?

Xinerama consists basically of two parts, the protocol to communicate the
position/sizes of screen between the Xserver and the applications (which
you usually get by enabling the xinerama use flag) and an xserver part
(module?) that you can use to set up the screens. What you said is
correct for the Xserver setup part...
You use either xinerama setup to put together completely different
displays (might be different cards, such as one nvidia, one ati, ...) 
or twinview in case of a dualhead nvidia setup. But both this setups use
the xinerama protocol to let the apps/wm know the placement of the monitors.

Hi I have X41Tablet too, although with the 2915ABG wifi chipset (because
of the built-in bluetooth ;-) but it uses the same driver and should
work in the same way (I used to have R51 with 2200).

As for the wifi, there are basically 3 different modes, unencrypted, WEP,
and WPA (there are many kinds of WPA, but that doesn't really matter in
the way of configuring it under gentoo w ipw2200).

For the unencrypted and WEP cases, all you need are wireless-tools and
gentoo initscripts, good examples are in /etc/conf.d/wireless.  You
configure few things for the whole interface (such as preferred_aps) and
others per access point (essid) such as encryption key and actual tcp/ip
configuration.  Gentoo initscripts than choose an access point in range
and connect to it.

Just put these into any of the relevant config files ( wireless, net,
net.eth0 or net.eth1 depending on which is your wifi, all in
/etc/conf.d):


# this should be default and thus not needed
modules_eth0=( "iwconfig" )

config_ESSID1=( "dhcp" ) # not needed too
key_ESSID1="abcdefabcd"

config_ESSID2=( "10.0.0.13 netmask 255.255.255.0" )
routes_ESSID2=( "defualt via 10.0.0.1"  )

...

Then just start the interface...

As for WPA you need additional software to do the encryption (well, to
the key exchange and such stuff...). The best choice now is
wpa_supplicant. In the /etc/conf.d/net.eth0 just put
modules_eth0=( "wpa_supplicant" )
and relevant config_ESSID and probably routes_ESSID (for dhcp you can
just leave it). To set up the WPA options you have to edit
/etc/wpa_supplicant/wpa_supplicant.conf.

There are many ways to do authentication/key exchange in WPA, from the
windows configuration on the page you mentioned it seems that you need
LEAP authentication (used by cisco) or PEAP + MSCHAPv2. The relevant part of the
wpa_supplicant should look like this:

network={
ssid="REftRW2d"
key_mgmt=IEEE8021X
eap=LEAP
identity="user"
password="pass"
}

or for PEAP+MSCHAPv2:
network={
ssid="REftRW2d"
key_mgmt=WPA-EAP
eap=PEAP
identity="user"
password="pass"
# this shiould not be needed
phase2="auth=MSCHAPV2"
}

I haven't actually used LEAP myself, so this is only a guess, feel free
to google for LEAP wpa_supplicant, or try asking people that managed to
get it running on your school. 

As for the essids (ssids), under root, just run
iwlist eth0 scan
to see the list of wireless networks in range (or use some graphical
utility). wpa_supplicant uses to power down the wifi, so you may need to
do
iwconfig eth0 txpower on
to see some results.


If you need more help, feel free to mail me off list...

if you run wpa_supplicant _through_ gentoo initscripts, they should run
dhcp when wpa_supplicant associates with the AP
(unless you define something else in config_=(...) )

just expanding your idea with pipes:

mkfifo f3
mplayer  whatever_options_you_want_and_make_it_write_to_stdout  | tee f1

I don't understand.
You don't need to do multiple reads from the fifo that mplayer writes to
(queue). Only one tee process (the first in the command) reads from it,
it "doubles" it and writes it to vo1 and its  stdout, and the second tee
reads that and doubles it again into vo2 and vo3. So after running that
command you can read simlutaneosly from vo1-3
(well you _have_ to read from all of them, otherwise tee will pause
writing to others)

Is it possible that you are booting into a different runlevel that
default ? (there's a softlevel=... kernel cmdline parameter)

What happens if (after boot) you just run

rc

(should start all service in the current runlevel, that are not
started yet)  or 

rc default

(should swithc to 'default' runlevel and start all services) ?

Could you post the output of  rc-status -a ?
And maybe also grep rc /etc/inittab ?

For xdm there is one additional thing to check: xdm can be disabled
through a 'nox' kernel cmdline option or an /etc/.noxdm file...
But in that case the initscript itself should start and just print a
message, that it is not starting the DM.

Hmm, the weird thing is that 'rc-status -a' and 'rc-update show' show
different things (no xdm and virtualbox-... in the first one) but I have
no idea what might be causing that...

Few random thoughts:

Did you check the file permissions on those scripts?

Any pending etc-update stuff (esp. in /etc/init.d) ? (not that it should
affect this in any way...)

If anything else, you can try running  'strace -e trace=file' on
rc-status and rc-update show and might notice something there that would
explain while those two tools come up with different sets of scripts...


You can also look around the dirs/files in /lib/rc/init.d/ to se a more
complete state of the rc system... (/lib/rc/init.d/softlevel should show
the current runlevel)

Also /var/log/kdm.log would be of use (if you are (well, want to ;)
using KDM as the login manager)... because it seems that the
problem might be with KDM greeter or something similar.

I had it segfaulting once, the symptoms were very similar,  KDM did
bring up X and start kdmgreet which crashed, X went down
immediately, because they had no clients, KDM noticed that X was
running only for a very short time and interpreted  that (correctly) as a
sign that something went wrong and didn't restart the X and insted just
stopped...

that would also explain why running startx works ...

btw, does 
startx /usr/bin/startkde 
start a KDE session?

Seems that rc-status sees the xdm initscript... but why doesn't it
show it then... no idea...

My advice would be to submit a bug, the inconsistent output from
rc-status vs rc-update is suspicious enough...

You might also try to re-emerge the packages that installs
/etc/init.d/xdm to see if that doesn't help... (should be
x11-base/xorg-server)

You should also ask on the gentoo-embedded mailling list. Mingw might not
be reallly 'embedded' but that list would still be the most relevant
place to ask gentoo-related crosscompile questions...
Gentoo also has a crossdev tool that should also support mingw, though I

Konsole should open the default browser set in KDE. 
You can check that in  systemsettings -> Workspace Appearance and
Behavior -> Default Applications -> Web Browser

IIRC some browsers allow you to 'set them as default' somewhere in their
menu (usually as an annoying popup at startup, until you disable it ;)
which should work with kde.. (at least i think it worked the last time i
tested it with chromium... but i mostly set it up manualy)

PA doesn't care about oss (/dev/dsp). It opens the soundcard through
normal alsa interface (which means /dev/dsp becomes busy). You can
either kill pulseaudio, or tell pulseaudio to suspend the correspondig
sink (not sure what exactly happens if an audio stream through PA is active
etc..).

Regarading oss (/dev/dsp) and plain alsa, it is the same, if something
opens the soundcard through alsa, /dev/dsp becomes busy... (even when
using dmix in alsa, because /dev/dsp is handled by a kernel modules,
dmix is userspace).

 There is however a way to amke oss work with dmix through aoss (a small
program that preloads a binary, that 'hijacks' calls to open /dev/dsp
and 'reroutes' that to alsa, works most of the time, but can have
problems if the program does some weird things...)
In that case aoss opens the alsa device "pcm.dsp" (or dsp0, i'm not sure
right now), which you can easily point to dmix...

from my /etc/asond.conf:

pcm.dsp {
type plug
slave.pcm "duplex"
}
pcm.dsp0 {
type plug
slave.pcm "duplex"
}
pcm.!default {
type plug
slave.pcm "duplex"
}
pcm.duplex {
type asym
playback.pcm "dmix:0"
capture.pcm "dsnoop:0"
}


Then you can run (even multiple) 'aoss mpg123 file.mp3 ...'


You can also make this to work alongside pulseaudio, if you configure
pulseaudio to use the dmix device instead of directyly using the hw
device.
Nnote that this might cause problems, you have to disable pulseaudio's
autodetect and configure all soundcards manually, and using dmix
introduces some additional overhead and probles, also such setup is most
probably not supported by pulseaudio etc... However it also enables you
tu run plain alsa apps alongside PA (officialy you should just configure the
!default device to use the PA alsa plugin is simpler and it should work
better, though I had some problems with some apps) and more importantly
to run multi PAs simultaneusly (ie for multiple users...)

My usual suspect for disk space in /usr/share/doc is kdelibs, with the
doc use flag turned on it installs the whole kde api documentation,
which takes a lot of space ...  so I either set -doc for
kde-base/kdelibs, or just set -doc globally and just enable it for
things i now I might need... (note that that won't remove all of the
/usr/share/doc dirs / files, but removes most of the large ones...)

For quick commandline viewing I use  xv, it is simple, just shows the
image, can show multiple images (space, backspace to go through them, q
to quit,) and  a few other resize / rotate options, if you rightclick on

Windows has (should have in a standard install ;) its own 'boot loader'
in its partition, it usually only installs a simple 'select the active
partition and boot from that' loader to the MBR, so in 99% it is enough
to just add 

title Windows
rootnoverify (hd0,0)
chainloader +1
makeactive


to /boot/grub/grub.conf, change (hd0,0) to whatever your windows
partition is ( hd0,0 is /dev/sda1, in hdX,Y  X is the disk number
(sda -> 0, sdb ->1, ..), Y is the partition number, counted from 0, ie
sda4 -> hd0,3)

it should be "(hd0,0)" and not "hd(0,0)"

that would explain the Error 11, which means the string describing the

I use an ext2 partition in a 500MB file image on most of my computers.
Its important to check the inode count on such small filesytem, as
mke2fs' default inode ration for such size is 4096, which is too
low for portage:

dd bs=$((500*1024*1024)) count=1 if=/dev/zero of=/usr/img_portage
mke2fs -f -b1024 -i2048 /usr/img_portage

fstab:
/usr/img_portage/usr/portage/   ext2loop,noatime
0 0
(this is from desktop, on servers I usually only mount it manually when
emerging)

don't know anything about the assus packages/drivers, but the general
direction in all such drivers is to move these things where they belong:
to the input subsystem, so my guess is the new driver doesn't produce
acpi events, but insted create a "input device" and produce key
press/release events on that device...

(note that sleep / hibernate actions are usually still reported also
throgh acpi, because some programs expect them to come from there, that
would explaing your Fn-F1/sleep working)

to test this, just run as root on the linux console (not in a termnal in
X):

showkey -s

and then pres the keys (ie Fn-F4,) to stop showkeys, just don't press
anything for 10 seconds...
if you see numbers appearing after each keypress / release, then the key
directly generates keyboard ivents  and its possible you will see them
directly in X, for that jus run (now under X)

xev

and (the window that appears must have focus / be active) press the keys
again, xev will print the X keycodes/keysyms to its output...
if you see reasonable names there, then you should be able to map those
keys in the programs you are using (ie global hotkeys in kde, etc...)
note however that qt/kde doesn't recognise some of the more exotic
keysyms...  (in my case XF86TouchpadToggle produced by Fn-F8 on
thinkpads ;)

if you can see the key in showkey -s  but not in xev, the problem might
be in kernel keyboard map (though i'm not sure if the x's evdev driver
uses that) or in the evdev driver not mapping that key

basically the kernel driver reports scan codes (what showkey -s shows),
kernel translates that to keycodes (showkey -k to see them) and then X's
input driver (ie evdev) translates those to the X keycodes X server
again trasnlates them to keysym-s

hmm, pppd  seems to bring the connection up ok and also to get the DNS
servers, however it might not set them correctly...

what's in /etc/resolv.conf after you connect ?

can you ping directly the other side of the ppp connection (ie
161.184.0.199 according to your logs):

ping 161.184.0.199

can you ping anything on internet through ip addresss:
ping 8.8.8.8

(8.8.8.8 are the google public dns servers)

you gave the same link for the last 3  ;)

but 50-initd.sh takes care of the case, when pppd is run through gentoo
scrips... in that case, when you run /etc/init.d/net.ppp0 start, the
net.ppp0 service is marked as 'inactive' istead of 'started' because
pppd didn't connect yet... when it connects, this script marks the
net.ppp0 service as started...


btw, i  newer used pon, i either used gentoo initscripts, or directly
started pppd ;), or  sometimes used kppp from kde3

but if your problem is with dns, maybe the pon script / program doesn't
start pppd with the usepeerdns option... (you might consider also adding
the debug options to pppd options..., but you have to find out how to do
that with pon)

with ppp connections you are not using a dhcp client, pppd gets the
nameserver ip addressess as part of the connection negotiation (if
peerdns is set) and the aforemetioned script in
/etc/ppp/ip-up.d/40-dns.sh writes those to /etc/resolv.conf

Are you using konsole ? As walter said, emerge sets the title of the
shell/terminal window to include the current package, however konsole
does not (by default) show the titles set by programs, but is configured
to only show the working dir and command name...

Just go to Settings -> Edit current profile -> Tabs  (tab ;) and 
you will see two things: Tab title format and Remote tab title format
(the defautl for the first is '%d: %n' == 'current dir: current
command', which is exactly what you wrote), just change them to '%w' and
you will get what every other decent terminal app shows ;) (you can
click the "Insert" dropdown to see other options)

use -p -f   (pretend and fetchonly)

emerge --pretend --fetchonly package...

it will output a line per each file/url you need to fetch (and put in
the distfiles dir), one line can contain multiple alternate urls (if there are
alternative mirrors etc...), you need to fetch only one of them

IIRC, it has a small downside, that it also lists the files you allready
have downloaded in distfiles (ie those for which emerge -pv would show
0kB as size of downloads...) so you might check the list against what
you allready have...

There are 3 solutions I can think of:

1. Get a cross compiler for i686 working under fedora (have no idea
about that, except manually setuping and compiling gcc) and setup the
Fedora's distcc to use that correctly (this should go more or less
according to the docs on the gentoo wiki regarding cmake and i686 vs
amd64)

2. Create a gentoo chroot on the Fedora OS. Much "lightweight" that a
virtual machine, you can setup the cross toolchain and distcc according
to the wiki, you just have to play a bit with how to start the distcc
inside the chroot (a plain /etc/init.d/distcc start inside the chroot 
won't work). Note that you can run a i686 chroot in an amd64 system, so
you actually don't need to set up any fancy crosscompiler inside the
chroot. Just run the chroot as 'linux32 chroot /mnt/chrooot ...' to make
sure uname and similar get correct info...

3. Mount the laptops root filesystem through nfs on the fast computer
(use no_root_squash on the laptop export to have correct root access to
files) bind-mount something local (disk or tmpfs if you have enough mem)
over /var/tmp/portage, chroot into it (don't forget to mount /proc,
maybe /sys and maybe bind-mount /dev, though that should not be needed
and don't forget 'linux32 chroot') and run emerges there... you will
actually be running everything on the fast computer, only the access to
the laptops disk will be through the network. With a fast network it
should be a lot faster then working ont the slower notebook (note that
if you bind-mount /var/tmp/portage inside the chroot, most of the
compilation will be working with a local disk...) Compared to the distcc
method, even the configure phases will be much faster...  I do this
often with my Pentium M 1.6Ghz thinkpad laptop and my quad core amd64
desktop...

Seems that the mic works, but is not selected for capture... (routing it
to speakers recording from it are two different things ;)

You basically need to tell alsa which sources to record from, which may
be different from which are just unmuted in the mixer (and thus playing
from the speakers). I've seen a few different sets of alsa controls on
different sound cards that control the record sources, these are the two I 
remember:

Run alsamixer, pres F4 (capture) and either look for
- a "mic" control (along with CD, Line, Aux,... controls), then make sure it 
has a red "CAPTURE" text (spacebar
  toggles CAPTURE)
- if you dont't have separate Mic, Line, ... controls, try looking for a
  "Input source" control, you should be able to use up/down arrows to
  change it to mic

Also in both cases make sure a "Capture" control has CAPTURE on too..
You might have more Mic sources two choose from, or you might also have
a "Mic Select" control, with which you can switch between different
mics, so you might have to experiment to find which is the correct
one...

btw, if I need to check if the network is up in a script, I usually do

ping -q -c1 -w4 some.remote.host >/dev/null 2>&1 && 
command-to-run-if-remote-host-reachable

It the advantage that it checks directly connection to the host
you wish to connect to, so it also won't run the command if your network
is up, but the remote host is inaccessible...

If your server doesn't respond to pings, just use some other server
(eg google's public dns 8.8.8.8)

The -w4 paramater controls  how long to wait for reply if the network is
up, but the reply is not comming (ie a network problem, if your network
connect is down, ping will return immediately with a "network
unreachable" or "unknown host" error)

Might be that something happens to X's DPI settings during the
suspend/resume...
You can try to comaper the outputs of 
xdpyinfo | egrep "dimensions|resolution"
and maybe 
xrandr
befor and after the suspend.

Also all the applications you metion are GTK V(well, I'm not sure about
opera...), does the same happen to qt, qk, plain xlib applications also?

It seems like X didn't switch the keyboard to raw mode or something like
this... The win key on linux console swithes to a previou vt (don't know
if it is intentional, or just a side effect of the kernel not correctly
handling it)

Sometimes, when an app freezes the whole X (usually when it grabs the
keyboard and freezes) I have to use the magic sysrq keys to "unraw" the
keyboard, which means I can that use alt-fX to swtich to text VTs, kill
the app and return to X... however from that moment on until I restart
X, the keyboard is not in raw mode and alt-fX and also the winkey switch
consoles (like you describe)

that console-kit-daemon is running doesn't mean your session is
'registered' with it, you can check with ck-list-sessions

yoyo@tabletka ~ $ ck-list-sessions 
Session18:
unix-user = '1000'
realname = '(null)'
seat = 'Seat18'
session-type = ''
active = FALSE
x11-display = ''
x11-display-device = ''
display-device = '/dev/ssh'

on-since = '2011-06-06T07:48:11.669544Z'

remote-host-name = ''
is-local = TRUE
on-since = '2011-06-01T17:09:37.282998Z'
login-session-id = ''

the defaults for disk mounting should be that only active (local?) sessions
can do it...

here it seems that a normaln console (text) / ssh  seesions
are registered in ck through pam, but X session's have to do that
manulally, which i guess is done either in DM's xsession script or in
the startup script of the chosen DE ...

if your session is not thare, then just add ck-launch-session to the
script you use to start the X session (~/.xinitrc in your case i guess, or
the script you specify to startx)

kernel modules are CONFIG_PROTECTED, so they are not automatically
removed when you uninstall / remerge the package (you have to remove
them manually), so you just have to remerge the package after you change
the /usr/src/linux symlink
there is also the module-rebuild utility, that automatically remerges
packages that installed a kernel module

i.e.

ln -sfn linux-VERSION1 /usr/src/linux
module-rebuild -X rebuild
ln -sfn linux-VERSION2 /usr/src/linux
module-rebuild -X rebuild
...

you might have to do 
module-rebuild populate
before the first time...

from the man page, this seems to do  what you want
(never tried, i use dhclient and its /etc/dhcp/dhclient.conf):

 -C, --nohook script
 Don't run this hook script.  Matches full name, or prefixed with 2 
numbers optionally ending with .sh.

 So to stop dhcpcd from touching your DNS or MTU settings you would 
do:-
   dhcpcd -C resolv.conf -C mtu eth0

[ 24703.710] (II) UnloadModule: "evdev"

you defined a (new) keyboard in the config, which doesn't actually point
to a device (the old kbd driver didn't need a device, but it didn't work
for other reasons...) so that X basically ignored that section
and your "real" keyboard device did get added automatically later
albeit without your settings...

the most correct way with a newer xorg is to create a file in
/etc/xorg.conf.d  where you put an entry, which would  *match*  your
keyboard device (that gets automatically created) and add the options to
it, basically something like:

Section "InputClass"
Identifier "pl keyboard layout"
MatchIsKeyboard "on"
Option "XkbModel" "evdev"
Option "XkbLayout""pl"
EndSection

can't find gentoo specific doc / page for this stuff, but
man xorg.conf (search for InputClass) and google for 
xorg.conf.d and/or InputClass should give you something usefull

locale.gen is in the install docs, because it allows you to choose which
locales should be built, ie after emerging libc, which locales you can
choose from... if you don't modify it, you get a lot of usual locales
built...

/etc/env.d/02locale is used to actually choose which one of the built
ones will be used as the "default" locale for (almost) everything that
runs... I gues it might deserve a mention in the install guide... 
though it actullly isn't any special file... the actuall locale is set
by setting an enviroment variable (LANG or the specific LC_...), you
could set it in your .bashrc / .bash_profile only for your user, or
anywhere where it would apply to most programs, ie /etc/profile ...
Gentoo has the mechanism, that anything that gets put into /etc/env.d is
then (through env-update, which you have certainly run from time to time
;) merged together to /etc/profile.env, which is in turned sourced by
/etc/profile (and posibly other things) so that it is just logical to
put it there... but the actual name of the file doesn't really matter ;)

as neil wrote, it is
nvidia-settings -c :0

nvidia-settings connects  to the remote xserver to communicate
with the graphics card (through a special nvidia xtenstion to the x
protocol), so you need to be able to access the remote xserver, if you
are logged in as the user running the xserver, you should be ok

To connect to an Xserver, you need to know its "address", which is
something like machine_or_ip:NUMNER for tcp/ip connection or just
:NUMBER for (local) unix socket connection.

BTW, as any other browser (well, new enough..), firefox starts
downloading as soon as you click on a link (ie, it dowloads it while you
are choosing where to save it, so that by the time you choose the
dir/filename, smaller files are allready downloaded ;).
You can easilly see this if you have some kind of network traffic monitoring
widget/applet/app...
I guess it starts to download it to a temp file, than moves it to the
file you choose (never looked into it)... so the problem would be most
likely in that operation..

You can mount --bind  a dir from a large partition to /var/tmp/portage
before an emerge, but you can't do that during a running emerge. However
with a reasonable buildsystem, you could in theory stop the emerge, copy
over the files in /var/tmp/portage to new location (preserving
timestamps) and then try resuming the emerge with FEATURES="keepwork
noclean", though i don't know if that works well with openoffice...

Also you don't have to mount anything to /var/tmp/portage, you can just
change the dir by setting PORTAGE_TMPDIR to a directory on a partition
with enough space (I normally have my DISTDIR, PKGDIR and PORTAGE_TMP set
on a different partition...)

Not "on a second partition" but under another "mount point" i.e. another
path... When you try to access a file by its filename, the kernel takes
the absolute file name, compares it to all the moutend "mount points",
takes the best match and tries to find (create)  the file in that
 filesystem/partition...

Lets say you do something like:

mount /dev/sda1 /  (well... you don't actually do this... ;)
mount /dev/sda2 /mnt/sda2
mount --bind /mnt/sda2/bigtmp  /tmp 

Then path "/home/yoyo/something" is accessing file "home/yoyo/something"
on partition sda1.

The path "/mnt/sda2/somedir/somefile" is accessing file "somedir/somefile"
on partion sda2.

The path "/tmp/somedir/somefile" is accessing file
"bigtmp/somdir/somefile" on partition sda2.


The files (and free space) under /mnt/sda2  and /tmp are actually on
partition sda2, everything else is on sda1...


So if sda1 runs out of space (by writing to other places than /mnt/sda2
and /tmp), it doesn't in any any way affect /mnt/sda2 and /tmp which
have their free space from sda2. Conversely if you fill up sda2 by
writing to /tmp, your "system" partition still has free space ;)

BTW, I was emerging libreoofice yesterday, and it took ~3.5 hours,
although OOo usually took ~1 hour. It seemed as if it wasn't doing
anything paralell, so I blamed my MAKEOPTS="-j -l4" (to which I changed
some time ago, but all the OOo compiles were before that). I just tried
today again with MAKEOPTS=-j4 and it took only ~1 hour ;).
Guess dmake doesn't know the --load-average stuff ;)

can't give a nice genlop -t output, as the first time i was building it
first with FEATURES=buildpkgonly and then installing with --usepkg (just
after i removed OOo), as portage didn't wan't to resolve the blocker,
and i didn't want to be without it while it compiled ... ;)


# genlop -t libreoffice

 Fri Jul 29 13:55:42 2011 >>> app-office/libreoffice-3.3.3
   merge time: 1 hour, 7 minutes and 25 seconds.

the first one is for the --usepkg binary merge ;), but I checked the

3.0 seems to be still ~, so i guess that for unstable kernel you might
need unstable drivers...

Also it seems that  modules_ethX shouldn't be an array, modules_eth0="!plug
!iproute2" uses ifconfig, modules_eth0=( "!plug" "!iproute2" ) uses
iproute2 ;)



As to why you have iproute2 installed... I always install it, so I can't
say which packages might be pulling it in, but you can use equery to
find out:

tableta ~ # equery depends iproute2
 * These packages depend on iproute2:
net-misc/openvpn-2.2.0-r1 (iproute2 ? sys-apps/iproute2[-minimal])

What about the env or echo $PATH output?

Might be that some files used to set up the enviroment are broken.
If PATH and maybe some other things are not set up correctly, that would
explain why login into KDE or anything graphical doesn't work...

You can try 
env-update && source /etc/profile

if that doesn't help, you will have to check the files that are read by
bash, mostyle /etc/profile (which should source /etc/profile.env among
others)


Check also files in users/roots homedir
(~/.bash_profile  / ~/.bashrc), but if the problem happes both with root
and regular user, I don't think the prob. is in those files.

NFS doesn't like when it looses connection to the server. The only
problems I had ever with NFS were because I forgot to unmout it before a
server restart or when I  took a computer (laptop) off to another
network...
Otherwise it works well, esp. when mounted ro on the clients, however
for distfiles it might make sense to allow the clients download and save
tarballs that are not there yet ;), though I never used it with many
computer emerging/downloading same same stuff, so can't say if locking
etc works correctly...

And with NFS the clients won't duplicate the files in their own
distfiles directories ;)

Nvidia driver doesn't use the xrandr protocol when dealing with multiple
monitors... they have their own extension and they say that it is better
and that xrandr is bad, and they report through xrandr only one output
(monitor) that covers all nvidia outputs. Thhat's the 'default' output
in your xrandr output, it's widht is the sum of widhts of both monitors
etc..

They report the physicall layout of monitors through the xinerama
extension, but  I guess that wacom uses xrandr (xinerama only numbers
the display, it doesn't have names, reports only a subset of randr
information and is generally older...)

I guess your only chance is to find parameters in the wacom display that
allow you to restrict the tablet to a certain area by setting the
coordinates... (and that would ofcourse work only for a specific
resolution...)

The usual way for linux on removable usb sticks / disks is to use LABEL
or UUID to identify the disks and not the device names, because they
will be different in different computers ;) The downside is that you
need an initrd to mount the root partition... I think that the usual
initrd generated by genkernel works...

If you created the rootfs with:
mkfs.ext2 -j -LUSBGentoo  /dev/sdXY

then you can change the kernel parameter to 
root=LABEL=USBGentoo

and your fstab to:
LABEL=USBGentoo /   ext3 ...

You can also use the uuid of the filesystem, find it out with
dumpe2fs -h  /dev/sdb2 | grep UUID
and then use UUID=XXX instead of LABEL=XXX

I never really played around with grub and  USB booting, so I use
syslinux. I create a small FAT partition with syslinux, kernel and
initrd image  (it gets also pretty handy when you sometimes need to copy
something from a windows machine ;) and a second "regular" ext3
partition for the rootfs.

Basically you would do:
- partition the stick, mark the FAT partition as bootable/active
- format the partitions:
  - mkfs.vfat -nUSBData /dev/sdX1
  - mkfs.ext2 -j -LUSBGentoo /dev/sdX2
- install syslinux (on the FAT partition):
  - syslinux /dev/sdX1
- mount /dev/sdX2, install gentoo in the usual way
- compile the kernel and initrd, make sure required USB stuff is in the kernel

To rule some other things out, you could also try:
unset DISPLAY
su -

DISPLAY is one of the differences between a text konsole and anything
under X... Might be that some bashrc/profile script tries to do
something with X if it sees DISPLAY, but isn't able to connect to X  under
root... (maybe some xauth stuff..)

Just to make it a bit more clear:
xrandr is used to setup the resolution and position of the monitors
(you can make them clone each other, overlap, be alongside / above /
below the other...)

How the windows / panels behave depends on your windows manager/desktop
environment (or on the panels themselves). X server provides them with
enough information about the layout of the monitors, and they have to
use it. So it depends on which DE or window manager you use...

In kde3,  there was a configuration option for kwin, whether windows
should be maximized across all screens  or on single screen...
I can't find it in kde4 settings right now, but I have only single head
card here and I guess it would be under "Multiple Monitors" option in
settings, which just says "You don't appear to have this configuration"
for me ;)

Plasma in kde4 manages things per monitor, so panels should be only
on one monitor (and you can't get them across multiple monitors, you
have to have a separate panel on each)...

Recent versions of fluxbox allow you to have the toolbar on a certain
monitor (head) or across all heads... Don't know how it is when maximizing
windows (some time ago I used to patch it to make it an option, didn't
play with it lately...)

I can't say anything for gnome or other DEs/WMs...

Intel drivers (for my thinkpad notebook) had a similar problem. If you
didn't use an xorg.conf, they would set up the max screen size to the
maximum possible resolution on one of the monitors... I haven't found a
way to change that without an xorg.conf... (didn't have much motivation
as I just always used an xorg.conf, event with hal... and I'm on ~arch,
so its not much of an issue now...)

PS right now, the current intel driver I have seems to have a hard maximum of
2048x2048 on my card, though I remember going above that in the

>From what I know (but I may be completely wrong ;) its this way:
the maximum size xrandr reports is what X thinks is the maximum possible
framebuffer size... Its reported by the graphics card driver, which (I
think) should be the maximum resolution the graphics card supports.
This depends on the card, the amount of memory it has (which gets a bit
complicated with cards with shared memory, that can dynamically allocate
how much they actually need) etc...

AFAIK this value is "constant" for X (it can't change without restart),
and X will never allow you to have a large 'virtual screen' (i.e.
the space in which all outputs have to fit)
