Bug Description
When using the new fast user switch applet to login a second user on my system, X restarts when left at the login screen for more than a few seconds. The error in my syslog is:
Oct 14 15:26:45 localhost gdm[13647]: WARNING: gdm_slave_
Steps to reproduce:
1 - Log in user 1 on first display
2 - Select a second user from the user switch applet
3 - Leave GDM screen showing for a few seconds without entering password

Hi there
Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Can you try with the development version of Ubuntu, Hardy Heron?
Thanks in advance.

Basilio - I was just about to respond to say that I haven't seen this bug for a while on Gutsy, and I that I hadn't seen it at all on Hardy- but it just happened on Hardy beta for the first time. My girlfriend logged in first, then I switched user using fast-user-switch (which is set to leave screen unlocked), then several minutes later - her Xorg dies on screen :0, causing GDM to restart and a login screen to reappear. I then logged in, and returned to my session where I left off before I was rudely interrupted by the crash.

If it's any help, this crash occurs when the screensaver activates on the inactive screen. I've got the screensaver set to 10 minutes, and it always crashes 10 minutes after switching users. If I lock screen and then switch users, Xorg crashes on the inactive screen as soon as the second user logs in.

After doing some debugging, it seems that this crash only occurs when 'BackingStore' is enabled in my xorg.conf. With the option commented out, I can log in multiple users without a crash (so far, so good), so I'm marking it as invalid now.

One other thing, I notice from your .nvidia-settings-rc that you are overriding applications FSAA settings. Do you actually load your nvidia-settings-rc (using nvidia-settings --load-config-only, usually added to session preferences)

When I debugged my crashes, I found that there were 2 problems causing them:
1) 'BackingStore' option in xorg.conf causes crashes when switching user every time.
2) OpenGL applications (glxgears, googleearth) cause Xorg to crash every-time when overriding FSAA settings in nvidia-settings. To fix this, I added the 'UseCompositeWr

I've run out of ideas, and thereby am forced to use 'nv' until any progress/change. ):
Maybe the bug isn't in NVIDIA itself, but in it's combination with Xorg 7.3. btw, Xorg states it's a pre-release and is not supported by original maintainers in any way; and we have that in LTS (!).

I get this problem with only 1 user. The computer crashes at random - no matter if I'm at the computer or not. My graphics card is an ATI 9800XT (with the proprietary drivers enabled).
The error started to appear after I installed a new SATA2-drive (samsung, 500Gb) to my machine. Before this there were no problem. Until yesterday I hadn't found any clues in the logs but yesterday my computer crashed twice and on both occasions the following log entries were found in daemon.log

i have this bug too. just started to happen today.
i am on 7.04 i386 desktop (running on a file server). the server is headless, so i log in via vnc on screen :1.
since today, when i log in to the desktop using vnc, then close the vnc session, the next time i log in, i am not getting back to the desktop where i left it, but to the login screen again. when i close the vnc session, it crashes X and restarts it, with the above error message.
therefore i doubt it's a nvidia driver issue.

If you don't need any 3D features you can also disable the nvidia

doesn't suffer from this problem.

Hi all,
Unfortunately, while the title of this bug looks technical and specific, in truth all it means is "X crashed for some reason". You'll see this message in gdm logs for any variety of different crashes, but I'm afraid people are finding this bug report and since the error message is the same are assuming they have the same bug. So I'm going to close this bug report so it doesn't continue to mislead people.
By default the information displayed in the log files when a crash occurs is insufficient to debug the issue. Instead, you'll need to collect a full backtrace - see http://

Actually, it still appears to crash even after logging in the second user. This is up-to-date Gutsy RC with nvidia 100.14.19 drivers
