Hello, I've had the identical problem (to 18 & 31) on several attempted installations of Ubuntu 12.04. Actually, no flickering but the wrong screen resolution until I change the refresh rate from 60 (incorrect) to 75 (correct). Then uncontrollable flickering. The wrong screen size I can live with but the flickering disables the machine (Dell Optiplex 745). Intel Corporation 82Q963/Q965 Integrated Graphics Controller (rev 02) video 20623 1 i915
I dual boot with Ubuntu 10.04 (where the graphics card works perfectly). The 12.04 file system is still intact. If anyone could advise me where I can change the refresh rate in 12.04 from 10.04, I'd be grateful for the workaround until a better solution is available. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/945006 Title: Screen flickers heavily after upgrading to 12.04 beta 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/945006/+subscriptions _______________________________________________ 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
