[Problem]
While on the console, within a few seconds it gradually fades to green. 
Corruption is also seen on the desktop.  With KMS disabled or vesa in use, no
such corruption is seen.

[Original Description]
I upgraded to Lucid and finally use the ati driver.

Every 5 seconds, my screen freezes and starts to become corrupted. It becomes
lighter and a light pink/green glow comes from the bottom of the screen and
starts to eat the screen until I move the mouse. When I move the mouse, it
takes 2 seconds to go back to normal but moving the mouse does not prevent the
corruption from appearing. (it's just needed to stop it once it started).

There's also some light garbage everywhere on the screen and the screen looks
striped.

Interestingly enough, the green/pink glow also appeas in console in X is
started.

This is for sure a ATI bug as there's no problem when using the VESA driver.

I've upgraded to kernel 2.6.32-17-generic and the freeze/glow disappeared.

Instead, the brightness is blinking and I can see some horizontal white lines
filckering on the screen. But at least, it is not freezing anymore.

(This is without the nomodeset option, still using the default kernel on grub.
I will reboot to try with nomodeset)

2.6.32-17-generic with nomodeset option : no problem, the bug disappeared.

(but the boot is ugly ;-) )
