Different behaviour handling NFS mounts after login
I've recently replaced Linux MINT on 3 machines with Debian Wheezy and GNOME3.4. All of my "shares" are mounted with NFS. For this purpose I use the following options (on all installations): rw,_netdev,hard,intr,user,nosuid,exec,async,auto Two of the machines opens Nautilus after each login. Neither the other installation of Debian nor a remaining MINT installations shows this behaviour. What's the problem here? Should I change something in the mount options?

I will try it this evening. I'm no NFS expert and I've "created" the mount entries a long time ago. The option "hard" was added because of the weakness of my first WLAN (years ago... now it is stable). Why do you think that changing this option influences the behaviour of GNOME?

How to mount a LUKS partiotion with Nautilus with option discard?
I'm using a separate LUKS encrypted partition on my SSD, which I only mount after login. Since there is now way to to this with crypttab/fstab, I have to use Nautilus to do this. I'm running a regular Debian Wheezy. After clicking on the (unmounted) LUKS partition, the system asks for the LUKS passphrase and than for the admin password. Now the partition is mounted as expected. The only problem is the missing 'discard' option, so I can't use fstrim with this partition. Does anyone knows some tricks how to add discard support?

Whats your way of sharing data between PCs?
Hi. I'm using Debian Wheezy on two Notebooks and one Desktop. All systems are using NFS to access a NAS. While the notebooks have all data on there local SSDs, the Desktop is working directly on the NFS share. I currently use Unison to sync the data between the notebooks and the NAS. This is very time consuming even with enabled "fast checking". I choose this solution because I need to take the notebooks with me. So I must have the data always up to date.

Debian8 is not playing with Synology using NFS/CIFS
It drives me crazy. Really. The company I'm working for is switching from a Dell server running Ubuntu to a Synology HA solution. On my desktop, I'm using Debian 8 and only Debian (Yes I know, I can be lucky ;-)). My first try was to mount the new shares using NFS4 and taraa... imapd. This fails because the ID mapping does not work. On both sides, the (same) domain is inserted into "/etc/imapd.conf". Without any changes. For now, I'm not really sure what ipmapd is for. A hoax? Fun? The second try was the ugly solution using CIFS. The bad insight this morning... Synology disables the "unix extensions". The second... There is no ID mapping too. My hope with CIFS was, that die total user and group stuff is done using "names" and not IDs. So, if anybody out there is running a Synology server. Is there a working solution to get uid/gip mapping, unix access flags and symlinks? I'm happy for every (positive) answer. ;-)

I think the whole NFS stuff is a really ugly and partly broken dinosaur. I'm using NFS (v3) for decades now, and all the glitches are still not really solved. And CIFS for Linux clients seems to be no way to go. I'm afraid I have to setup Kerberos to work-around the broken ipmapd stuff. More than a little bit "oversized"... Thanks for the help!
Difference between LUKS drives with cryptsetup and Disks?
I've created a LUKS partition which I mount on demand. This partition was created using cryptsetup. While mounting the partition, GNOME asks me first for the passphrase and than for the "admin" password. A while ago, I've created a LUKS partition on an USB thumb drive using GNOME Disks. In this case, mounting requires only the passphrase. And that doesn't depend on the used computer! What is the difference? Can I change the behavior of my older LUKS partition too?

Just a thought... I'm running Debian Jessie and I see the same behavior with my Thinkpad T500. In my case the reason is the Network Manager. I have 2 NFS shares mounted over Wifi. The Network Manager stops Wifi before unmounting the NFS shares. This leads to a long time out. After that, I see the "Reached target Shutdown" message and the system in still powered. I have to unmount the NFS volumes first and than I can shutdown the system.
problems with moving the toolsbars of Inkscape
I'm using Inkscape from Jessie and have some trouble with the arrangement of the toolbars. I've written a bug report (#797148) two weeks ago, but without reactions for now. The positioning of the toolbars is only in some (rare) cases possible. It is very hard to find a place where the moved toolbar snaps into a position. Most bars doesn't snap to any position. A second effect is the length of the bar. While moving the toolbar, the length of the bar is not truncated to the space needed, so that dragging a bar in fullscreen mode is not possible. What are your experiences with moving the toolsbars? Are there any solutions or work-arounds?
Wie restauriert man alte NetworkManager Konfigurationen?
Ich habe nach meinem Upgrade von Wheezy auf Jessie die VPN-Konfiguration aufgeschoben. Nun wollte ich das nachholen und habe (ganz blauäugig) die alte Datei unter /etc/NetworkManager/system-connections wieder einsortiert. Leider erkennt der NetworkManager die Datei nicht. Zumindest zeigt er die Verbindung nicht and. Muss ich sonst noch etwas machen?

gnome-power-manager compatible with systemd?
I have installed a standard Debian Jessie (with systemd and GNOME3) on my older T500 (dual core). For some reasons, the *power statistics monitor* is not installed by default. Is there a reason for that? Is it save to install gnome-power-manager (only to get the monitor) or does it may cause an conflict with the power management (if any) of systemd? If have installed gnome-power-manager now without warnings. After that, the T500 doesn't shutdown completely. I had not have the time to debug this on the weekend, but as far as I remember, this wasn't the case before the installation of gnome-power-manager.
VPN connection no longer available for me as user
I run into a bug where nm-connection-editor doesn't read the password out of the settings. And without password it doesn't save changes. I hadn't recognized this first, so that I tested editing the setup as root. The console outputs leads me to a solution. After saving my changes as root, I no longer have access to the VPN. Even the entry isn't visible. Within the configuration file, I have found the following line. permissions=user:root:; I've changed it back to my login name, but it still doesn't work. How can I change the permissions back to me as owner?

System freezes after update to Jessie 8.4
I have an extremely hard problem after upgrading Debian Jessie from 8.3 to 8.4 today. The system is a Dell Vostro with an AMD/ATI Turks PRO [Radeon HD 7570]. The free radeon driver is used for X. Desktop is GNOME3. The resolution is 25560x1440. I've used this resolution for about 3-4 weeks now. After the upgrade (and a restart), the system freezes from one second to the other. It seems to be independent from the used application. As a work-around, I'm running GNOME classic now. Without the EGL features, the desktop is running now. Currently I avoid using Firefox, because I don't know if the renderer uses EGL. Can someone help?

Re: System freezes after update to Jessie 8.4 [workaround]
My personal workaround... yesterday, I had used GNOME3 Classic which reduced the freezes down to "every3 hours". ;-) Today morning, I've downgrades the kernel back to the previous version and I'm back to GNOME3 and Firefox for 2 hours now. No freeze so far... What I've done is: aptitude install linux-image-3.16.0-4-amd64=3.16.7-ckt20-1+deb8u4 linux- headers-3.16.0-4-common=3.16.7-ckt20-1+deb8u4 linux-headers-3.16.0-4- amd64=3.16.7-ckt20-1+deb8u4
Bug: updating Debian9 not "allowed".
I'm still running Debian 8 on all of my systems. Since it is time to switch to Debian 9, I've tried to have a first look at it. So I've installed the nonfree DVD-Image 9.2 within a VirtualBox container. All went fine, until I've tried to update the APT database. Both, apt and Synaptics updates fails. In both cases the error reports, that /etc/apt/trusted.gpg is not accessible by user "_apt". The recommendation I've found was to delete trusted.gpg. OK, this was a workaround for using apt. Both update and upgrade works without errors. Trying Synaptics leads to the previous behavior. The file trusted.gpg appears again and with this file, the error returns. By the way... Why is the VirtualBox Guest Utils package not available in the official repositories?

It is hard to believe that this bug is known since June and that there is neither a fix nor a solution. Deleting the file has worked for me, but I can't say that there are no side effects. How should a newbie solve this? Without a work-around there are no updates possible.
how to enable trim for an external encrypted SSD?
Normally I would enable TRIM support in the /etc/fstab or the /etc/ crypttab by add the discard option. Now I have bought a SanDisk Extreme Portable SSD. My goal is to add a LUKS encrypted partition without an explicit fstab entry. I've done this with some USB thumbdrives before, but not with TRIM support. The drvie should be plugged into any Linux device without the need to change the configuration. What is the correct way to add TRIM support to an external SSD with LUKS encrypted partition?

Thanks for your detailed and extensive answer. That's exactly the answer I was afraid of. ;-) So I will add an entry to the /etc/crypttab and hope that fstrim will do it's job. All system without a modified crypttab should mount the device but fstrim will fail. I think I can live with that solution. > You could ask the LUKS developers to include an additional flag in their > headers that allows you to specify that this volume should be opened > with discards allowed by default That is a good idea. I think I will write an ticket for that. Thanks again.

I've used a ext4 formatted, unencrypted (!) 64GB SanDisk Extreme USB 3.0 thumbdrive together with Unison. I sync a collection of documentation, some application configurations and a bunch of git repositories to it. The sync was done 4-5 days a week. The amount of changes was less than 5MB a day. IMO SanDisk is a trustful company with products of high quality. But the thumbdrive has not even lasted a year! By the way... hdparm reports that the thumbdrive supports TRIM, but I was never able to use it! So much for the topic "the firmware will do that". ;-)

I want to use fstrim in favour to the discard option. But I've tested it with an Arch Linux installation with a more fresh kernel. There both vairante (fstrim and discard-option in fstab) fails too. In case of the discard option, the error is written to the logs. > What does the command > findmnt | grep /media/jd/TEST $ findmnt | grep /media/jd/TEST ├─/media/jd/TEST /dev/sdg1 ext4 rw,nosuid,nodev,relatime,data=ordered $ sudo lsblk -D [sudo] password for jd: NAME DISC-ALN DISC-GRAN DISC-MAX DISC-ZERO sda 0 512B 2G 0 ├─sda10 512B 2G 0 └─sda20 512B 2G 0 sdb 00B 0B 0 sdg 00B 0B 0 └─sdg100B 0B 0 In this case, sda is a internal SSD (Samsung EVO) with working TRIM and sdb is a HDD.

Arch Linux (that I tried) comes with a recent kernel and this still not work. Unfortunately I can't say much more about that, I've never had an external SSD. I had the same situation with my Sandisc Exreme thumb drive before! Here heparin reports TRIM too, and fstrim failed too. At that time I thought that the problem is the thumb drive controller. A thumb drive is no SSD. As a result of the missing TRIM, the drive shows IO errors after just 1 year of usage. That could become an expensive hobby. :-/
