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. -- video problem flicker unreadable hp compaq nx9420 ati radeon https://bugs.launchpad.net/bugs/537640 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
