Debian :: Log Off/log On As Different User Breaks X Apps Under 5.0.1?
Jun 26, 2009
I've just installed Debian 5.0.1 (i386; network install) and I've run into a bizarre issue that I have no idea how to troubleshoot. If I log on as (e.g.) User1, log off, and then try to log on again as User2, X-based (i.e. not terminal) software will fail to load until I reboot. After logging on as User2, all X software (including the Gnome interface) will display its interface for a fraction of a second before vanishing from the screen and the task bar. One time the Gnome interface wouldn't load after log-on: the taskbar and menubar repeatedly flashed on and off the screen as Gnome repeatedly tried and failed to load.

I have two internal partitions that I auto-mount at startup using fstab. This works fine & I can unmount/mount as a normal user no problem in the terminal (umount /dev/sdb1) but using thunar (or nautilus) I receive a message saying "not authorised to perform operation" (I use the DWM window manager, in gnome it pops up with a password prompt).
If I open thunar as root then I can mount/unmount.
The strange thing is I can mount/unmount usb sticks or mtp devices as a normal user no probs from thunar! So, I'm assuming it must be my fstab that's the problem?
Code:
Select allLABEL="DebianLive" / ext4 errors=remount-ro 0 1
/dev/sda6 none swap sw 0 0
/dev/disk/by-label/Vault /media/Vault ext4 users,auto,exec 0 0
/dev/disk/by-label/LiveJob /media/LiveJob ext4 users,auto,exec 0 0
This used to work fine on my wheezy install, only started having problems when I switched to Jessie ....

In Karmic, I could run an app as user gdm by issuing the following command (assume the app is gconf-editor)
Code:
gksudo -u gdm dbus-launch gconf-editor
Now that I've switched to Marverick when I issu the same command I get this:
Code:
towheed@GA1A4CH:~$ gksudo -u gdm dbus-launch gconf-editor
No protocol specifiedNo protocol specified
** (gconf-editor:19812): CRITICAL **: Failed to parse arguments: Cannot open display:
I checked my environment variable DISPLAY using:
Code:
towheed@GA1A4CH:~$ echo $DISPLAY
and it returned:
Code:
:0.0
Now I ran the command:
Code:
gksudo -u gdm dbus-launch gconf-editor --display=:0.0
and got the same error as before.Has either or both dbus-launch or gksudo changed their behavior os is this a bug. Note that the command does not work with any applications being run as the user gdm.

I'm running a java app when my specific user (not root) login. It's running fine.The problem is that profile.local are calling my app twice ... The first call, it's blocking Linux environment until I close java app. After that, occurs the second call, then it's free Linux for usage.I tried to change my java app for gedit, and I can see the problem too.I tried with profile.local and /home/<my user>/.profile, the result is the same.

Using opensuse 11.1 64 bit with kde 4.1.3, apps like k3b, or any multimedia apps can not see the optical drives unless I run the apps as root. I also found that to run bladeenc, I have to do it in a root terminal. Is there a way to set permissions for the normal user? Firefox or any text editor work fine as normal user.

yesterday I updated my squeeze amd64 on my Phenom X4 and now it is not booting anymore. Have you experienced the same problem?
After that I noticed the shutdown was not working anymore, it just restarted instead of powering down. This morning it wouldn't boot squeeze anymore, when grub starts and prints "Welcome to grub" (or something like that) the list of operating systems is not shown.
I noticed the updated also included grub and I saw it correctly detected my operating systems.
I am planning to boot knoppix soon and try to reinstall grub from chroot, but currently I am at work.

I just upgraded to lenny (stable) from a working etch system. It went pretty nicely but I'm having a problem with the print system.
Ok, I have an HP Laserjet 4M+ connected to my system by USB. (I have another color printer too and a scanner but I don't use them often).
I use CUPS. I never bothered with the HPLIP packages because straight cups has always worked well.
What happens now is that I'll send a job to the printer and nothing will happen. The printer won't get it. Looking at CUPS on the localhost:631 page I can see that the printer is on, connected, ready; the job is there too but just stuck on "processing".
Now here's the thing. If I manually load the ehci_hcd module with "modprobe ehci_hcd" then the job will make it to the printer and it will print.
I can't just make that module load at boot time because if I do and the printer is off, it doesn't work. (I have to unload it and reload it). For whatever reason, I have to make sure that module gets loaded AFTER the printer is turned on, or nothing gets sent to the printer!

Enabling kernel modesetting on my computer breaks graphics, but Xorg.log and syslog don't tell me much, because they don't log any error.
The symptoms are the following: boot goes on normally, then the KDM login screen is corrupted. On the login screen there is a big square instead of the cursor, and that square does move as I move the mouse. If I press Ctrl+Alt+F1 I'll get a black screen instead of the terminal, and from there I cannot go back to virtual terminal 7 for login. The only thing I can do is to issue sys-requests for read-only remount and reboot.
Where could I start looking for the problem? What does it seem to be related to, Xorg, kernel, radeon driver?

I have installed the latest virtualbox 4.1 on my desktop and laptop. It hosed suspend and hibernate.
The laptop is A Dell D630 with Intel Core2 Duo CPU, the desktop is an AMD based ASUS M3N78-VM mobo with Athlon II x2 250 CPU. Debian Testing 32-bit (same results with the 2.6.39 and the 3.0 kernels). Both have nvidia cards though - the desktop an integrated 8200, the laptop a NVS 135M. But suspend/hibernate was working before with the 4.0 series virtualbox.
The workaround is to clear the vboxpci vboxnetadp vboxnetflt vboxdrv modules from the memory before suspend/hibernate. I added the
service vboxdrv stop
rmmod vboxpci vboxnetadp vboxnetflt vboxdrv
lines to my sleep script (i dont use power managers, just the acpi powerbutton/lid scripts modified). Everything is ok now.

Today I find myself in need of a good gapless cd player for linux, again. I've recently made the switch from gentoo to debian and I really like it. I used aqualung as my cd player while using gentoo , but the version of aqualung in Debian is currently broken. I've tried compiling and installing a newer version, but that one couldn't play audio cd's at all, probably due to older dependancies.
I can't install packages from squeeze or sid without having to upgrade a lot of things (like libc6) and that's not something I want to do. Are there any other gapless audio cd players out there for linux? All of the major audio players I've tried so far (rhythmbox, mplayer, totem, etc.) insert gaps in between the tracks - which to me is really annoying, but from the look of things it must not bother other people that much.

Note: I use debian testing.GUI very frequently completely breaks for me, it looks like this:URL....It usually happens after a short freeze or after going back to GUI from TTY (which doesn't display because of a known Nvidia proprietary driver issue).And sometimes my laptop goes into sleep state by itself while it's being used. This is lenovo ideapad z510 laptop, with intel+nvidia GPU (nvidia Optimus). To use nvidia GPU I use bumblebee.

I upgraded testing today on my intel laptop. During the upgrade I got the message that the new kernel would require additional firmware, see attached. Is the solution for this to install the driver from Realtek? [URL] If so, the instructions said to check if the driver was already installed, but what does the output below mean?
conor@con-u3s:~$ lsmod | grep r8169

I have just updated my Squeeze system. The update included a newer version of network-manager (and it can not be more than a few hours old). After the update all network functionality on my machine (via knetwork-manager) is broken. The GUI applet has no effect.
Hence can anyone help me: a) Downgrade network-manager by one version; b) Find out what is causing knetworkmanager to break; c) See if the problem is with knetworkmanager or network-manager.

I just updated my Debian testing as usual (apt-get update && apt-get dist-upgrade), and it totally screwed up Nvidia drivers. I had to revert to integrated graphic card to start Xorg.
After that, I noticed that libgl1-nvidia-glx is missing, and when I tried to install it back, it produces the following:
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
libgl1-nvidia-glx : Depends: libgl1-nvidia-alternatives but it is not going to be installed
E: Broken packages
Any ideas what's going on with it?

I'm trying to install Atheros AR9485 wireless card driver on debian, and I had no luck.
I followed this [URL] .... to install backports kernel version. The wireless card worked, however, intel display driver displayed the color in the wrong way.
Red pixels are green, and green are yellow. It was displayed like when someone try to connect a PAL system to a TV that supports only NTSC.
This is my lspci output:
Code: Select all00:00.0 Host bridge: Intel Corporation Haswell-ULT DRAM Controller (rev 09)
00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 09)
00:03.0 Audio device: Intel Corporation Device 0a0c (rev 09)
00:14.0 USB controller: Intel Corporation Lynx Point-LP USB xHCI HC (rev 04)
00:16.0 Communication controller: Intel Corporation Lynx Point-LP HECI #0 (rev 04)
[Code] ....
Is there is a way to compile only AR9485 module from the kernel?
Add the following
Code: Select alli915.i915_enable_fbc=0 to your GRUB_CMDLINE_LINUX_DEFAULT= in /etc/default/grub so you would have something like that
Code: Select allGRUB_CMDLINE_LINUX_DEFAULT=" i915.i915_enable_fbc=0 nomodeset quiet splash"

OS: Debian 5.0.4
Server: Apache2
I've used mod_rewrite to rewrite my apache2 root (my.server.com/) to point to /var/www/drupal6/ instead of /var/www/. I also have a script installed in my cgi-bin (/usr/lib/cgi-bin) but since the rewrite I can't seem to access it. When I go to my.server.come/cgi-bin/test.pl, I get a page not found from my drupal.
Is there a way I can access my cgi-bin without resorting to accessing my drupal through my.server.com/drupal6/?
Background: I have installed drupal CMS which has a base address of my.server.com/drupal6/ as it resided in /var/www/drupal6/. However I wanted users to be able to access it as my.server.com/ so I added the following into my httpd.conf
Code:
NameVirtualHost *:80
<Directory /var/www/drupal6>
RewriteEngine on
RewriteBase /
[Code].....

I'm trying to get compiz setup but it is not having any affect at all. I installed it and went to the synaptic system manager and added all the compiz plugins that were there. I restarted several times before and after going to the synaptic system manager. It said installed successfully, however it has no effect so it isn't "on" whatsoever. I have watched ..... tutorials on how to set it up. It looked easy enough but did not work for me. I have tried commands from tutorials but I don't know enough or how to edit folder contents. I think they were old tutorials anyways, I am running the newest squeeze debian distro. The 3d desktop was one reason I wanted to try linux. If I can't get the basic apps like this to work then there is no reason for me to use linux.

it was difficult for me to get it set up. So, when Squeeze became the stable release, I strayed. Tried Ubuntu, Mandriva, PCLOS, Mepis, both KDE and Gnome, and after using Lenny for several months, they all sucked. So I'm back, and although it took me several hours, over a few days, and 50 searches, I have Squeeze set up just how I want. I love how fast and stable it is!!
I've become a big fan of Gnome over the past year, because of how simple, fast and stable it is. But, there are a few KDE apps I prefer over the ones available for Gnome. I want to install K3b, KTorrent, digiKam/showFoto, and probably Amarok (although I haven't given Rythembox a fair chance). I realize this will install the KDE base, but other than the space taken up, is there any disadvantage to doing this? If there's a chance it will affect the speed and stability of the system, I'll learn to live without them.
Is there a way to extract the MD5 SUM from a .iso I download in Gnome?? K3b does it automatically before the burn. Does Brasero do this and I'm just missing it?
I've tried using Transmission a few times before to download torrents, but never with success, yet with KTorrent, I just click on the file and it starts downloading it.

If I wanted to avoid installing certain i386 apps from the repository, could I somehow compile my own (generic compiling, or for deb packages) with an i686 architecture in mind?Would this be congruent with the rest of the Debian OS, or would the extra instructions cause instability (if even possible)?

I have read this simple instruction to get me tweetdeck into my desktop computer (AMD Athlon X2, 2GB ram, 160gb HDD - Debian SID)[URL]
I'm not sure what happened but installing Adobe Air in Debian is like installing in Windows XP -- I used the .bin file instead of the .deb because the .deb say's Adobe Air is 32 bit application.
So it is installed (sucessful or not I still don't know) -=- I go to tweetdeck site and got to its desktop page where there should be an install button -- however, there aren't any or it wont show -- it partially show like a running circle but it's not running. Then when I click on it -- it disappears.
I tried installing other air app like livebrush but the same -- the button is not shown. My Sid is updated as of now. I also have google chrome browser -- the behavior is the same as with iceweasel v3.5.10

I'm having a problem getting a winTV card working. Looks like the card installs correctly and I know the card works ok. I get "no device" when trying to use TV apps (kdetv, tvtime, xawtv). They look for the device at video0 but mine gets configured as video1. How can I change that? I have tried using ivtv-ctl -d /dev/video1 to change the device but that didn't help.

I installed Debian lenny amd64 a couple days ago and I have only got a few things figured out thus far. I got libdvdcss, and adobe flash along with some neat little games and apps. Well I had no sound at all because I couldn't get my audigy ls working with lenny so I'm useing my onboard sound (a realtek). I changed all my sound options to ALC 880 Analog now I have sound for movies and mp3's but not in games or on the web (ie ....., farmville).

Running Lenny in my plain vanilla x86 box since Lenny went final. No video card. System is completely up to date with the 26-2 kernel. All apps are Deb stable from repos.
chkrootkit, rkhunter, and clamav have all been run within the last 24 hours (clean). Firestarter is the firewall.
I left the box with about 10 apps running over all 4 virtual desktops (KDE). Came back in a couple of hours to find all apps closed except Gkrellm. Boinc, which had been dormant for lack of work, had gotten some jobs and was running in background. All apps reopened normally except Iceweasel did show the "closed unexpectedly" notification. I don't use a screensaver.
System did not shutdown and auto reboot. Uptime clock and syslog had chugged along right through it. Syslog seemed normal except for the exerpts below that looked curious to me.

I recently upgraded my Debian kernel to 2.6.35 via backports and reinstalled my graphic driver. But when I try to use certain apps, it just sits there in the taskbar trying to load for a couple minutes, then automatically closes itself. Specifically I've noticed the nvidia x-server menu and open office doing this, while they both worked fine before I upgraded the kernel. some apps will do this, while others will work fine.
