This problem will occur with kernel version 3.1 or higher on my 2730p. For the 2730p, this seems to have been fixed, according to https://bugs.freedesktop.org/show_bug.cgi?id=43123. The patch mentioned there also solves another video issue, see https://bugs.launchpad.net/gentoo/+bug/796030.
Please test the kernel in the proposed repository. ** Bug watch added: freedesktop.org Bugzilla #43123 https://bugs.freedesktop.org/show_bug.cgi?id=43123 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
