Comment 117 for bug 745112

Current Precise still has this bug. I also tried with the current drm-intel-next kernel from <http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-next/2012-01-05-precise/> and I had the same problem.

Bug 906086 is about a kernel oops when trying to use the external display. I have not seen that recently, but the description from the upstream suggests it may be intermittent (it's a use-after-free bug.)
