Subject: gdm: erratically switches off computer without asking
Date: Sat, 12 Sep 2009 11:05:27 +0200
Package: gdm
Version: 2.20.7-4lenny1
Severity: normal
The system is powered down immediately at unforeseeable times without even proper
shutdown, causing data loss and destroying recordable media being burned. This happens
around once or twice daily at irregular times. It is of no importance which programs are
running or if a screensaver is configured. It happens regardless of user activity, even in
the middle of the night.
It does not happen, however, as long as:
- GDM and X are not running at all
or:
- GDM is showing the greeter (i.e., X is running)
(I tested this for about a week each.)
--- i.e., it only happens in a user session
Once it has happened, the computer may even switch off once or twice a few seconds after
restarting. Then things calm down.
There are no discernable hardware problems such as overheating, fan failure or harddisk
failure. I have installed monitors.

This is a kernel or X driver bug.
What is your graphics hardware (it appears in lspci) and what is the
driver you are using?

I don't believe the problem is X's fault because it does not occur in GDM's graphical
login screen even if I leave the computer in this state for days; neither can it be the
kernel's fault because it does not happen in console mode (i.e. without GDM and X). It
only occurs in a graphical user session.

I attach my /etc/X11/xorg.conf.
I'll test some things to narrow down the list of suspects:
1. GDM configuration settings --- I'll leave the computer on not in GDM's login screen
nor while I'm logged in in GDM but in a newly created default user's session
2. power management (although I'm not using this)
3. the window manager
Of course, I am open and grateful to any suggestions.

Actually it could be your CPU or RAM. Please run a full memtest86, at
least.
In all cases a hardware lockup cannot be caused solely by userland.

I have narrowed it down: it only occurs in _my_ GDM session. If I create a new user and
login as this user, the problem does not occur.
> Actually it could be your CPU or RAM. Please run a full memtest86, at least.
The memory checked out alright. It would seem like a hradware problem, though --- if it
were not limited to my sessions. It has nothing to do with load, either --- the memory
test put the CPUs under quite some stress, and temperatures soared --- without causing any
problems. Then I did some video encoding with a lot of load as well as memory and harddisk
usage --- again without any problems.
> In all cases a hardware lockup cannot be caused solely by userland.
I do realise that. That is why I believe it must be some program with suid rights --- like
GDM.
Best wishes,
Axel

Even for programs running as root, a power down without proper shutdown
should never happen. Do you still have this problem today? If so
maybe dmesg or syslog has a clue?
Cheers,
Julien

Thanks for the followup, I'll close the bug as unreproducible then.
Happy to hear you don't have this problem any more.
