yes its exactly how it happens, one minute i'm  reading the wikipedia 
(or simply staring ate the screen) the next minute its garbled. It
never happens at server startup and i dont know if it happens in
3d apps since i dont use 3d (cant enable dri thanks to unsuported agp)

when the screen is corrupted, any XV movie that i put (via mplayer) show 
corrupted also and if i switch to the console (vt0) and back
both are corrupted.

my console is a radeon fb set at the same resolution i use in X 
(1600x1200-85)

when this happend the first time, i even tought of hardware problem
but a simple shutdown -r now
clear all display corruption, so i sort of ruled out a problem in the card 
(the card is also visualy ok )

that left me stuck :)

will try your tips and see if the corruption goes away
this machine has 3Gb of memory, can it have anything to do with it ?

thanks a lot
