I have this same issue with both 12.04 and 12.10... don't think it's a kernel problem. Using ctrl-alt-F1 at boot-up black screen and using terminal to issue these: sudo service lightdm restart immediately brings up the desktop, Unity3D, Intel HD3000, dual SSDs, 8GB RAM.
Seems the parsing of tests for hi-res video card is the issue. frank -- 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 low graphics mode with Intel HD graphics To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1070150/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
