Comment 7 for bug 537640

I see a similar problem on a HP Pavilion dv2 after upgrading from 9.10. The video card as reported by lspci is:

01:00.0 VGA compatible controller: ATI Technologies Inc Mobility Radeon HD 3400 Series

The problem also appears using the live CD. I followed the instructions for removing fglrx and reinstalling the ati driver, but it didn't help. Using the radeonhd driver the flicker goes away, but rendering is very slow.

The flicker also appears during startup and shutdown when the splash screen is shown, even if radeonhd is selected in xorg.conf.
