[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 ;-) )

There's also a couple videos, probably too large to attach in bugzilla, but here's launchpad links:

Some further comments from the reporter:

"""
With the latest upgrade (changelog says that DKMS is now enabled by default), the bug happens all the time, even with the nomodeset option or an old kernel. It looks like the nomodeset option is not working. (= The computer is totally unusable on Lucid)

Also, it happens in recovery mode in console, as soon as the driver is loaded, without starting X!

Finally, it seems to be related to the heat. In the morning, it doesn't happen for hours then it starts and become more and more frequent. Even full shut down are not sufficient. Shutting down the computer for one hour make it bug free for a couple of hours again.
