Description of problem:
On my Inspiron 8500 laptop using an ATI radeon mobility 9000 card selecting screen resolutions of 1280x720, 1024x768 or lower results in the LCD panel display breaking up, as if it is failing to sync properly. Resolutions of 1280x768 or higher up to the maximum of 1920x1200 are fine.
This makes it problematical to to switch to a lower resolution for the benefit of driving a data projector.
Reverting to xorg-x11-drv-ati-6.6.3-4 fixes the problem.
The same problem is present when installing Fedora 8 from DVD, the graphical installation mode was unuseable.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Select a display resolution of 1024x768 (by any means)
2.Watch the display fail to sync
