Bug Description
I finally was able to recreate the problem.
My laptop is running Gutsy (though this problem also occurred with Fiesty).
Every time the system was idle for several hours, with nothing but screen saver running, the system froze completely.
No kbd/mouse/
I though it might be a heating problem, but it turned out not to.
I checked it with a 3D game "TuxKart". I brought the system to 50 deg but still working.
Then I tried to run 2 GLXGears simultaneously.
I almost instantly caused the system to freeze (few seconds). Temperature at freezing point was 46 deg.
I did that check several times. It still is the case.
I saw a bug here related to large memory usage which causes the system to freeze, but I was not sure if this is the case.
Anyway, I can recreate the problem again.
some details about my machine:
LG laptop. Model F1.
cpu: Intel Core Duo T2350, 1.86 GHz
RAM: 2GB

I am not sure which extra data is needed (not sure how to report a bug), so please inform me and I will supply it.
Ok.
My apology.
I cannot recreate the bug.
The checked it for 3 consecutive times (each time running 2 GLXgears at the same time and each time I had to forcefully restart the system due to complete freezing).
But now I checked it again and I was able to run 6 GLXgears without any problem.
But the system still freezes after long period of idle (screensaver).
Oh well ... back to the drawing board.
