The whole point of that script is to provide those two filesystems in case the user "forgot" to specify them in /etc/fstab. If this is reproducible (say, after next reboot devpts still doesn't come up, while devfs is started), then something is wrong. Filing a bug report likely won't help because it works on mostly everyone else's system; you should probably ping the list again to find out what the source of the problem is. A work around would be to just add the appropriate line to /etc/fstab. the devfs script is smart enough to check if the devpts and tmpfs are already mounted, so it should break anything additional.

It seems that ext3 doesn't support > anything larger than 4K? The problem is not when you are making the filesystem with mke2fs, but when you partitioned the disk using fdisk. I'm sure I am making some small mistakes in the explanation below, but it goes something like this: a) The harddrive with 4K sectors allows the head to efficiently read/write 4K sized blocks at a time. b) However, to be compatible in hardware, the harddrive allows 512B sized blocks to be addressed. In reality, this means that you can individually address the 8 512B-sized chunks of the 4K sized blocks, but each will count as a separate operation. To illustrate: say the hardware has some sector X of size 4K. It has 8 addressable slots inside X1 ... X8 each of size 512B. If your OS clusters read/writes on the 512B level, it will send 8 commands to read the info in those 8 blocks separately. If your OS clusters in 4K, it will send one command. So in the stupid analysis I give here, it will take 8 times as long for the 512B addressing to read the same data, since it will take 8 passes, and each time inefficiently reading only 1/8 of the data required. Now in reality, drives are smarter than that: if all 8 of those are sent in sequence, sometimes the drives will cluster them together in one read. c) A problem occurs, however, when your OS deals with 4K clusters but when you make the partition, the partition is offset! Imagine the physical read sectors of your disk looking like but when you make your partitions, somehow you partitioned it This is possible because the drive allows addressing by 512K chunks. So for some reason one of your partitions starts halfway inside a physical sector. What is the problem with this? Now suppose your OS sends data to be written to the block. If it were completely aligned, the drive will just go kink-move the head to the block, and overwrite it with this information. But since half of the block is over the phsical sector, and half over , what the disk now needs to do is to pass 1) read pass 2) modify the second half of to match the first half of pass 3) write pass 4) read pass 5) modify the first half of to match the second half of pass 6) write Or what is known as a read-modify-write operation. Thus the disk becomes a lot less efficient. -- Now, I don't know if this is the actual problem is causing your performance problems. But this may be it. When you use fdisk, it defaults to aligning the partition to cylinder boundaries, and use the default (from ancient times) value of 63 x (512B sized) sectors per track. Since 63 is not evenly divisible by 8, you see that quite likely some of your partitions are not aligned to the physical sector boundaries. If you use cfdisk, you can try to change the geometry with the command g. Or you can use the command u to change the units used in the partitioning to either sectors or megabytes, and make sure your partition sizes are a multiple of 8 in the former, or an integer in the latter. Again, take what I wrote with a grain of salt: this information came from the research I did a little while back after reading the slashdot article on this 4K switch. So being my own understanding, it may not completely be correct. HTH, W -- Willie W. Wong ww...@math.princeton.edu Data aequatione quotcunque fluentes quantitae involvente fluxiones invenire et v

My personal experience has been the opposite: cfdisk writes (and demands) better formed partition tables, so sometimes crap that fdisk can read/write will not work with cfdisk. But of course, YMMV.

It is possible you can use some of those; I never tried. That's a negligible amount of space on modern harddrives anyway. And actually, starting on sector number 63 means that you are skipping 63 sectors, not 62, since LBA numbering starts with 0. Historically there is a reason for all drives coming with default formatting with the first partition at section 63. Sector 0 is the MBR, which you shouldn't overwrite. MSDOS and all Windows up to XP requires the partitions be aligned on Cylinder boundary. So it is safest to just partition the drive, by default, such that the first partition starts at LBA 63, or the 64th sector, or the first sector of the second cylinder. Actually, this is why Western Digital et al are releasing this flood of 4K physical sector discs now. Windows XP has been EOLed and Vista and up supports partitioning not on cylinder boundary. If Windows XP still had support, this order of magnitude inefficiency wouldn't have been overlooked by most consumers. > I bought this 500GB drive for my laptop recently and did a fresh partitioning > scheme on it, and then rsynced the filesystems of the old, smaller drive onto > it.

Are you sharing the harddrive with a Windows operating system? Especially Windows XP? There are reports that Windows XP supports partitioning not aligned to cylinder boundary. However, if you are dual booting you will almost surely be fscked if you try that.

I've always assumed by default that computer programmers starts counting at 0.

[gentoo-user] Two problems with xdg-open
Hi list: What exactly is xdg-open and how to I configure it to do what I want? The question came up because I am using jabref, a Java based bibtex management system. On my home machine, when I tried to open a PDF file, java throws a file-not-found error on "xdg-open". But I have xdg-utils installed, and xdg-open is found in /usr/bin. Right now I have gotten around the problem by configuring jabref explicitly to use xpdf to load PDF files. For all I know this is probably a environment/PATH issue in the load script for jabref. I took a look at the man page for xdg-open, and find the concept intriguing. The idea seems useful. But how does one go about "setting the default" programs for various documents? If I try to issue "xdg-open file.pdf", it tries to load firefox, which then asks me where to save the pdf file. This is rather obviously not the desired behaviour. Maybe I'm blind or something, but I don't see anything in the man page about how it determines what is the user's preferred application. Cheers, W -- Willie W.

I am getting rather confused by this back and forth (I thought I understood what you wanted and Dirk and other's answers should be right, but now I am not so sure). Can you answer the following for me just to make sure we are on the same page? (a) What is mpdscribble?

Can you give me a description of what commands you want to execute and what you want to accomplish with those? (c) I noticed that in your previous e-mail you spelled it mpdscrible with only one b. Is that a typo in the e-mail, or is it actually how you have it in /etc/conf.d/mpd? emerge --search suggests that mpdscribble is spelled with two b's.

In Gnome at least you can high-light with mouse, right click, hit copy, and go to another window, right click, and hit paste Is visual mode even suppose to work for this purpose?

So basically the problem is OO then. Can you copy and paste from other applications to OO? Perhaps it is a problem with encodings? Years ago I had trouble occasionally when I try to copy and past stuff from Firefox to Vim in a rxvt terminal. Then I found out the hiccup is due to 'proper' apostrophes, commas, and en- and em-dashes. Unicode characters does not want to be pasted into a non-unicode terminal. try emerging (if you don't have it installed already) the little program 'xsel'. You can use it to manipulate the selection buffers. Try trouble shooting with it to see what the problem is. http://www.vergenet.net/~conrad/software/xsel/xsel.1x.html HTH, W -- Willie W.

Okay, so OO does smart pasting where it also treats formatting I guess.

It is trying to be too smart with the paste-buffer. Somehow it is not treating the selection as pure text as it ought to. Out of curiosity, does this happen for any text file in gvim or only those with certain file extensions? I assume it is also a problem when you just open up vim with an empty buffer and type some random junk and try to copy and paste that? No, I don't use OO at all, and much as I'd like to help, I'm not about to try to install *that* on my underpowered netbook. Actually, I don't even use gvim: vim in a terminal is good enough for me. Hum, just a thought! Do you have vim compiled with the vim-with-x USE flag? Try toggling it. Part of the flag is supposed to help behaviour with interaction against X clipboard.

If you are interested, take a look at less `which xdg-open` and you will be enlightened as to why it is a complete piece of crap unless you are using KDE, GNOME, or XFCE. (Hint, notice how nowhere in the script does it read whatever you modified with xdg-mime.) A possible way to work around it (depends on your application, which, in your case, is beagle, which I am not familiar with) is to go into the offending application that is calling xdg-open and see if you can configure MIME types in there yourself.

But it works. It is my pdf viewer of choice at home. One thing I am waiting to see is epdf from the enlightenment libraries. It is still masked, and is in the enlightenment overlay. In the sunrise overlay there is a program called apvlv. I have never tried it myself, but the codebase is small and it has a UI based on the VIM UI (for better or for worse).

Ack, let's do this one step at a time then. First let's try to figure out the problem with the gpg-agent. This time, run the command from gpg-agent, not inside a eval statement. Just by itself on the commandline. It should spit out the environmental variable GPG_AGENT_INFO. Copy the content of that variable (so copy the whole thing GPG_AGENT_INFO="..." ) In a new prompt, first paste the variable, then type gpg -vv *file* So it should be GPG_AGENT_INFO=".." gpg -vv DATA/filename.ogg Quick explanation: gpg finds out where the agent is by looking at the environmental variable GPG_AGENT_INFO. We want to try to make sure it is in fact looking at that variable. Take a look at the man pages for gpg-agent and gpg for more information. Now look at the output again to see if it is still connecting to the "wrong" socket. W -- Willie W.

I'd file it against gpg-agent and hope that if it is something related to the qt3-qt4 transition, one of the bug-wranglers will cc the qt team.

Did you change the block size? You mean the other way around, right? reiser defaults to tail-packing, which can cause problems with GRUB and LILO, which is why notail is an option which turns off tail-packing for those crazy enough to use reiser on /boot. If you use notail on the portage tree, you get rid of that advantage, then Neil is absolutely correct: there's not too much point in journaling the portage tree, and if you actively make reiser not-competitive on the storage-space direction, the only metric left to compare is speed, and ext2 is faster. Incidentally, if you are willing to sacrifice speed for space, then a sparsefile for /usr/portage may also be an option. W -- Willie W.

I am rather curious what application you are using to get battery

/proc/acpi/battery/BAT0/state is 0444 on my netbook/laptop since

For builds, is it really wise to do all updates unattended? Also, for builds, there is such a thing as elogs (which allows you to save all messages to /var/log/portage for ease of reading at your leisure. You can even configure it to select what types of messages are saved): I neither need nor want to scroll through pages and pages of mostly useless output only to find the ewarn messages. I'm sure you have a good reason for wanting to do things your way, and I do not claim mine is better.

When the filesystem fills up, services can start failing left and right because they cannot write logs, cannot write temp files, etc. At this point human intervention is necessary: root has to log in and clear out the disk. But if the $ROOT filesystem is completely full, one may not even be able to log in and/or that one cannot do any sort of maintenance that is needed. So you have some sort of circularity. (In which case you have to reboot, perhaps using another medium...) The way out is to reserve some breathing room for root so that when everybody else is having problems he can still get in and fix the problem. The 5% is historical from days when disks are much smaller. If you have a sensible partition scheme you only really need to reserve the blocks on the $ROOT filesystem. If the partition in question (IIRC) is only for /home, then you can just turn off the reserved blocks all together. Cheers, W -- Willie W.

Just as an aside, my issue with the 2.6.32 kernels turns out to be a bios bug: the bios reports the lid to my netbook is closed even when it is open (cat /proc/acpi/button/lid/LID0/state shows 'closed'). Now starting kernel 2.6.32 apparently the KMS was 'fixed' to trust the bios reporting, hence it does not think *any* computer display is attached to the computer. This leads to a kernel error on boot and a blank screen. Anyway, Pablo (whoever you are: thanks!), a gentoo user, commented on a Ubuntu bug report https://bugs.launchpad.net/ubuntu/+source/linux/+bug/515246/comments/55 and provided the RTFM response: apparently we can override the bios by passing a suitable boot parameter to explicitly enable the LCD display on the laptop. With this now I'll be able to upgrade to a newer version of the kernel and test out the new intel X drivers. Cheers, W -- Willie W.

I see, I was trying to figure out what they meant by deprecated and how they determined it. It seems that the only thing common to those packages is that their ebuilds are no-longer in the tree.

Precisely. But the exact version that is installed is no longer in the tree. Seeing that I don't recall the portage system introducing a deprecated flag (short of the removal notice and package.mask), I was curious how eclean determined that those packages are deprecated. And also seeing that for many of the ones I listed, neither emerge --update --deep world nor emerge --update --deep --with-bdeps=y world suggest their updates, in my case they are probably just cruft that ought to go away once the system is brought up to date and I can run depclean. But am I wrong in my impression that with bdeps, the common thing to do is to update them only when absolutely necessary? So in this case the deprecation warning might introduce unnecessary cycles spent on building those packages (among those who don't want to track down the origins of those packages and just want the block of text to go away).

With the intel driver and X, he needs to have kernel mode setting enabled. I seem to remember that it doesn't play well with the vga mode setting for framebuffers. But Walter: you should be able to add a line on your lilo/grub prompt for the Intel KMS to set the display resolution at boot time. See the Kernel documentation in /usr/src/linux for the Intel GMA driver for more info on that. (Technically you should be able to rung the console at a different resolution than X; there may require another tweak at the kernel level to make the switch to VT after starting X play nice. See the gentoo-wiki article on Kernel Mode Setting.) Also, have you tried just using larger fonts on the console? If you emerge sys-apps/kbd, there should be some fonts in /usr/share/consolefonts. You can use "setfont " to test which one you want to use (some of them are bigger fonts). You may also want to try media-fonts/terminus-font (what I use), it claims to have a 16x32 variant which is twice as large as the default console fonts. After finding a font you like you can set it in /etc/conf.d/consolefont to automatically load at boot time. Cheers, W -- Willie W.

Are you sure there's no kernel trouble _very early_ in the boot process? I don't know about the Dell model you have, is it a laptop? Some motherboard BIOS/ACPI are known to have a bug where they mis-report the lid status of the laptop, and so on boot the computer "thinks" the lid is closed and turns off the screen.

So the in-kernel configuration parameter should be k (=18 in your case), and the boot-time parameter should be 2^k (=262144). Cheers, W -- Willie W.

No, the link in your sig didn't work, it returned a 404. In any case, if the gentoo maintainers don't want to deal with it, and if you really need it, and if you can't convince them to switch, then maybe it is time to try a new distro? Also, just because it is not *sanctioned* by the maintainers doesn't mean it cannot go in an overlay somewhere. W -- Willie W.

Hum, do this for me, would ya? (1) what happens when you run AUTOSSH_POLL=100 /usr/lib/autossh/autossh .

It only happens with interactive scripts that display a menu using 'dev-util/dialog'. Most of the time it works, sometimes it doesn't: after the previous dialog clears the screen, screen just sits there blinking and not loading the next one. I'd be interested in a solution too, if there is one. W -- Willie W.

Another vote for fvwm2. Like someone else said, fvwm does almost nothing by default, but boy is it configurable :) And yes, it does support multiple desktops... the only limit to how many I think is your RAM. You mentioned keyboard useable. I dunno if it will help, but my old mouse/keyboard config is available here http://www.math.princeton.edu/~wwong/fvwm/MouseKeyboardConfig.fvwm2rc With my definitions I *can* use fvwm without using the mouse at all, but I still use it to access the menu for convenience (the Menu key on my laptop is not where one normally expects it to be).

It may help if you point us to the screen shot. But quite a few X applications allow drawing directly to the root window.
