https://bugs.freedesktop.org/show_bug.cgi?id=76483 --- Comment #8 from Damien Diederen --- (In reply to comment #5) Hi Ilia, Ben, I gave a shot at drm-next as of the following commit: > commit bc1dfff04a5d4064ba0db1fab13f84ab4f333d2b > Merge: c1a6e9f 1ae5a62 > Author: Dave Airlie > Date: Wed Jun 11 16:28:10 2014 +1000 > > Merge branch 'drm-nouveau-next' of git://anongit.freedesktop.org/git/nouveau > > display rework fixes lots of displayport issues. I have been running that kernel for a large part of a work day, and, so far, it has worked pretty well. Many thanks! Below are a couple remaining issues, none of which are blocking in my case (GeForce 9400/DP/Dell U2711), but which may be worth investigating if they also happen with other hardware combinations: 1. The display does not wake up from (timed-out or forced) sleep on keypress or mouse move as it used to. Activating the OSD menu wakes up the panel; Nouveau seems to pick that up as a hint to get going; 2. The panel's backlight flickers very noticeably after a soft power cycle. It also flickers, but less noticeably, after a hard unplug/ re-plug. Force-switching to an unconnected input source and back makes it stable again. Let me know if there's any way I can assist you further. In the meantime, thanks again—it seems I'm not stuck with 3.8 anymore!
