GDM logout or crash wont restart X server

delerious010 · 2008-11-12 03:33:53

Got a wierd problem here and I sure could use some help.

GDM starts up fine.
I can log into Gnome without any issues.
I can lock screen with gnome-screensaver and unlock without issues.

However, if I Ctrl+Alt+Backspace or logout of my gnome session, I see GDM shut down which brings me to a black screen. Then, the screen powers off and I'm forced to reboot.

Trying to get to a console with Ctrl+1 or Ctrl+Alt+1 will not do anything.

nvidia 177.80-2
gdm 2.20.8-2
xorg-server 1.4.2-2

xorg.conf generated by nvidia-xconfig
only modification :

What happens when switching between X and the consoles?

I don't use gdm, but my intel card won't let me switch between graphic and console. My system freezes up.

Finding this out will help you narrow down the problem to being an Xorg issue or a GDM issue.

Pretty sure it's a GDM issue.
Switching doesn't generate any issues.
All problems revolve around restarting GDM

Hmm I'm not sure, however I don't know if you typo'd but to switch you should be using CTRL+ALT+F1

Have you checked your X logs?

Um, ya, ctrl+alt+F1 .. stupid typo.

Found the problem, seems like it was a conflict with uvesafb.
Removed it from my initrd and now I'm golden.

Thanks fo rthe help pyther

I've had this exact problem. Booting into GDM is fine. Even using user switching is fine. However, once I logout and it has to restart gdm, it fails and I get the failed to start X message. I tested to see if it was GDM or X, and its definitely GDM since startx works fine. I checked the GDM logs but all it shows is the normal X logs, which have no problems.

I first realized I was started gdm as a daemon in rc.conf as well as trying to run it through inittab. I removed gdm in the rc.conf and made sure my inittab is set to default runlevel of 5 and had gdm as my login manager. Still no go. Any help would be appreciated.

Hi, have you solved this problem? I have exactly the same problem with you, but i'm with fglrx driver. I'm not sure if this is a gdm problem or X, but logout is fine when using xf86-video-ati driver.

Really annoying problem to me, I DO NOT want to restart PC just to have a X related configuration taking effect.

EDIT: well, after a little experiment, I can confirm that it's not GDM's problem, it might be X Server or Graphics card driver's problem. I set inittab to not boot into gdm, but start gnome via startx (modify .xinitrc). The first time(I mean after boot into console, then type startx for the first time) X server start up correctly, then I logged out, and type startx for the second time, then caused a kernel panic, I have to shutdown laptop by pressing power button for 3 seconds. Since GDM didn't run at all, so I say it should be X server or graphics driver's fault.

Any idea?

I'm getting this too, except it also happens with KDM.
