Bug Description
Binary package hint: gdm
Hi,
I ain't quite sure if this is a gdm problem, it might also be x.org... please reassign if necessary (or ask me for any additional info you may need).
This has already happened a handful of times. Some times (e.g. when I have a lot of unfinished work and open windows) I leave my work PC on and logged in during the night, and when I come back, it is at the gdm login screen.
Inspecting /var/log/wtmp (using "last") I notice that tty7 is marked as "gone - no logout"... my pts/X are shown as all logged out at the same time.
Looking at that time in /var/log/syslog I find the following:
############### /var/log/syslog ###############
Mar 26 21:38:06 kamchatka gdm[12964]: WARNING: gdm_slave_
Mar 26 21:38:07 kamchatka kile: *** glibc detected *** kile: corrupted double-linked list: 0x08eae7f0 ***
Mar 26 21:38:08 kamchatka acpid: client connected from 24269[0:0]
Mar 26 21:38:10 kamchatka kernel: [738623.073704] mtrr: type mismatch for d0000000,10000000 old: write-back new: write-combining
Mar 26 21:38:10 kamchatka kernel: [738623.562071] set status page addr 0x00033000
############### /var/log/syslog ###############
(the "kile" error only happens if kile is running, I've seen similar logs without it)
I find that these errors are correlated to an error like the following in /var/log/gdm/:0.log
############### /var/log/gdm/:0.log ###############
X: ../common/
############### /var/log/gdm/:0.log ###############
The only other log I could correlate was auth.log stating that my gdm session was closed:
############### /var/log/auth.log ###############
Mar 26 21:38:07 kamchatka gdm[12964]: pam_unix(
############### /var/log/auth.log ###############
I'm using Intrepid with gnome in a Dell Optiplex 755 ultra small factor with an Intel graphics card.
Stuff (that I can remember) that was running at that time:
gdm 2.20.8-0ubuntu3
firefox 3.0.7+nobinonly
thunderbird 2.0.0.21+
gnome-terminal 2.24.1.1-0ubuntu1
kile 1:2.0.1-1ubuntu1

the issue seems rather an xorg one
