dmesg

When I unplug and replug DP connector the screen becomes corrupted (until I
restart X).

I attached dmesg file. At 266s I plug DP connector, so that part of dmesg
corresponds to screen corruption. Then at 386s I restart X, so that part
corresponds to the working state.

I suppose nouveau DDX is doing something wrong because this only happens with
X. E.g. everything is fine if I start Wayland.

I'm running:
Linux kernel:        3.14.1
xf86-video-nouveau:    1.0.10
xorg-server:        1.15.0
