Confirmed. My LCD screen started to flicer after installation of graphic drivers (Nvidia).
It seems the problem is somwhere before graphic driver initialization. After switching from Auto to fixed rate 50Hz or 60Hz (Refresh rate => NVidia XServer settings) flickering stopped. -- 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
