This has also hit me on fresh 12.10 AMD64 install with a Thinkpad T530 with Intel HD4000 and SSD.

The listed workaround of restarting lightdm also works for me. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1070150 Title: Intermittent black screen or low graphics mode message To manage notifications about this bug go to: https://bugs.launchpad.net/lightdm/+bug/1070150/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
