https://bugzilla.kernel.org/show_bug.cgi?id=83331 --- Comment #5 from Klaus Kusche <klaus.kusche@xxxxxxxxxxxxxxx> --- Any news on this one? Some more info's: 1.) Still there on 3.16.2. 2.) My workaround (disabling and re-enabling the internal output) takes ages: ~: time xrandr --output eDP --off ; time xrandr --output eDP --auto real 0m0.516s user 0m0.003s sys 0m0.004s real 0m7.832s user 0m0.000s sys 0m0.003s Times are very reproducible, almost constant (+/- 5 ms only). During these commands, the system is more or less blocked, in spite of the CPU being idle. Also, the first timing is not displayed after half a second on the external monitor as one would expect from its real time, but after 6 seconds, one second before the second timing. What are these commands doing that long? 3.) A similar problem seems to affect switching from VGA to FB console during kernel bootup: * It takes ages (I counted more than 5 seconds on a really fast machine). * It sometimes shows the same strange white moving stripes during the switch. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
