Bug Description

After logging into GNOME session, the system crashes when user generates some activity - even the simplest one like opening a text file with gvim. I expected to conduct my work, but instead, the system crashed in an unusually hard way.

The system crashes so hard, that even numlock doesn't blink (the keyboard doesn't work) and when the on/off button is pushed (which is the only way out), the system shuts down, even though normally, when I push this button, the system restarts itself.
Another weird thing is that the screen sometimes disbands itself (?some graphics-related issue..?), last time the screen only went blank. And the (cpu) fan starts to work harder (is making more noise).

Extra info:
When the user doesn't do anything after logging in, the system doesn't crash/freeze, at least during the first five minutes.

release: Lucid beta, on 5.4.2010
system: Asus F5RL
graphics: Ati radeon X1100, using open source ati driver

The problem disappeared. May have been caused by setting CPU mode to "Performance", which lead to crash due to high temperatures.
