[Bug 42156] gdm

[ozonehole]

Public bug reported:

Affects: abiword (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed


Description:
On an IBM ThinkPad X31 (laptop), whenever I log out (and thus reach the
gdm-based login screen), if I move the mouse cursor the screen will
crash. The screen becomes garbled, the mouse cursor disappears, and I
can't log back in. Only way out of this is to hard reset, though since
the laptop lacks a reset button, that means pulling the plug and
removing the battery (the power button is frozen too).

Note that this is not a problem at the initial login screen. I must
first log in, then log out, and then I'll experience the crash. If I
don't touch the mouse, I can log back in again as the same or another
user. It's only if I touch the mouse at this point will I experience the
crash.

I tried to reproduce this problem on my desktop machine, an AMD64-based
computer with an ATI Radeon card. There was no problem. It seems to be
limited to the laptop.

Let me know if you need any log files for more hardware info.

I've considered that possibility that it's the xorg package and not gdm,
but I never experience this issue after I'm logged in. It's only at the
login screen that I encounter this. I have updated to the latest xorg
package.

cheers,
Robert (ozonehole)
