Comment 8 for bug 512387

Thanks for reconfirming it's still an issue for you for lucid. It sounds like this is an issue with the kernel drm code, which is not handing the video output correctly. Since 319717 has been closed, I'm assuming your issue is somewhat different from that one so rather than reopening it, we'll move *this* bug to the kernel team to look into.

One thing you could try as a possible workaround is to turn off KMS (i915.modeset=0 in grub).
