I seem to have the same problem here. I was running ubuntu 12.04 with kernel 3.2.0-26-generic-pae just fine on my laptop (Samsung NP530U4B) when a kernel update came along. It updated to 3.2.0-27-generic-pae and the flickering began. At first it all seemed fine, until the screen was dimmed because of inactivity and the screen started flickering. All this flickering blocked everything (I could move the mouse but the clicks were not responding). The flickering seemed to stop at random (sometimes playing with the brightness buttons) or not at all (I had to power off my laptop). This also happens with the recent kernel version (3.2.0-29 -generic-pae) which I've just installed.
At the moment I'm stuck with running in 3.2.0-26-generic-pae where this flickering is not an issue... hopefully this gets fixed soon in the kernel (or the video drivers, whichever is the problem here...) -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
