I've reviewed the aforementioned bug reports. It is striking they have such similar symptoms and are mostly Arrandale/x86_64 specific, but there are subtle differences in symptoms so I'm unsure they're all duplicates.
There are a variety of Arrandale (aka Ironlake) kernel patches proposed upstream at http://lists.freedesktop.org/archives/intel- gfx/2011-April/010071.html. Some of those patches are experimental bits, others are merely shuffling code around for refactoring, so it's difficult to spot the actual fixes we should care about. In any case, I think the next action for this bug report is that we need people to test this intel-drm-next-proposed branch and tell us whether it fixes the issue; if so then the actual fixes can be git-bisected, or if not we should forward the bugs upstream. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/747205 Title: [arrandale] Black screen on all outputs when external VGA is connected -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
