Occasionally, the LCD display on my Presario notebook "dissolves" to a white
screen while running X. The only recovery is to shut it if off for a while.
It seems this happens when the computer gets very hot as if the video card
is overheating (?). But it has never happened under Windo$e. Any ideas how
to prevent this? Maybe sync rates that are too high or otherwise set
I am running xfree 4.02 (although the same happened under 3.x). I have an
ATI Rage Pro Mobility with Mach64 chipset, and I selected the default Mach64
driver and settings when I (auto) configured X.
Thanks for any ideas,
