Comment 20 for bug 255601

Mickey: Thank you for posting your results after your (probably) time consuming research.

This used to work flawlessly with nouveau and (apparently) never with the blob. I'm using your suggestion now.

For now, the nouveau drivers (apparently) suffers from the same issue. But only after I upgraded to a new userspace (not the kernel).
