Lock screen causes X to crash

[Luc Stroobant]

Binary package hint: gnome-screensaver

Well, it's all in the subject. When I hit "lock screen" or my screensaver activates and wants to lock the screen, X crashes and after a few seconds I get a new gdm login prompt.

This is on an HP Compaq nc6320 in a docking station with an external HP1740 17" screen. I guess the issue might be related to the dual-screen setup.
VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03)

I don't think I'm the only one with this problem, check http://ubuntuforums.org/showthread.php?t=60671 , but I couldn't find an existing bug report for the issue.

Please, can you attach your .xsession-errors file located in your home directory?

[Luc Stroobant (ubuntu-stroobant)]

As requested, my .xsession-errors.

I also experience this crash. This was after i updated the kernel to 2.6.22-14-generic from 2.6.22.13-generic. I upgraded yesterday ( 10/09/2007 )at around 9:00AM - everything still worked. This morning (10/10/2007) around 10AM i upgraded again. This broke the screensaver. My .xsession-error look similar to the one already posted. I am using an ATI X700 with binary fgrlx driver.

Thanks in advance.

I am also seeing this crash. I am using a Dell Latitude D610 laptop on a docking station with a 17" Dell M770 CRT Monitor. I have a onboard Intel 910 video card and using the 910 driver (not the default settings, the only way I found to get multiple monitors working). I have dual monitors/xinerama setup. I'm able to preview the screen saver fine, but when I attempt to lock the screen with GLMatrix, X restarts. If I choose a blank screen saver the screen locks fine. This problem may have to do with OpenGL and xinerama. This worked fine with Edgy, this problem started today when I installed Gutsy RC (fully updated).
