Today my laptop froze after it waking up. I rebooted my laptop, saw the grub screen, hit enter, and then everything got scrambled as seen below: (sorry, not enough karma to embed)

This scrambling is not confined to the splash screen. It persists after logging in. I restarted and booted windows 7 without issues. This leads me to believe that the cause is some funky driver update.

Has anyone else experienced this? I've tried running 'dpkg-reconfigure -phigh xserver-xorg' from the command line. I've also purged the xserver-xorg package and resinstalled it. Any ideas? Can I maybe roll back the driver to a previous version (assuming that is the case)? If so what package contains the Intel graphics drivers?

can you check whether the shape of the distortion changes when you change resolution? I guess it is an unsupported resolution / refresh rate, or better a not functioning one in your driver version. – Michael K Feb 1 '12 at 12:45
Nope, same distortion just at a lower resolution. – circlingthesun Feb 1 '12 at 13:27
I just re-installed Ubuntu. Everything worked fine. Then I updated it, restarted, and now I'm back at square 1. This is a freshly updated base install with no 3rd party packages. – circlingthesun Feb 1 '12 at 15:32
I've narrowed this down to a problem with the kernel. It happens after upgrading from the to kernel. I've filed a bug report here: – circlingthesun Feb 2 '12 at 0:39
