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. 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 signature.asc Description: Digital signature

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.

Bug#546291: gdm: erratically switches off computer without asking
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.
