(In reply to Alex Belykh from comment #46) > Funnily enough, if I boot with either of monitors detached, it boots and > works fine, and if I then reattach the second monitor and connect it with > xrandr, everything keeps working fine. I can confirm the effectiveness of this workaround. Booting with only one monitor attached and adding the other one later results in being able to force performance levels and also in correct automatic level adjustments (when not forced). Maybe this workaround is the key to solving this issue. Now I can run the system in both the working and the screwed-up state with otherwise the same hardware configuration and log internal information. There has to be some loggable difference between the two. I just don't know, what to look for (never did any kernel development), so I'd need someone to provide the log statements and interpret their output. -- 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
