<pre>After few more tests it looks like every single docking attempt on 4.6.0 ends
up with inability to use DP1-2. When on DP1-1, $ xrandr --output DP1-2 --auto
returns "xrandr: Configure crtc 0 failed"
However, with command:
xrandr --output DP1-1 --off; sleep 2; xrandr --output DP1-2 --auto
I am able to switch to DP1-2. But then I am no longer able to use DP1-1:
$ xrandr --output DP1-1 --off; sleep 2; xrandr --output DP1-2 --auto; xrandr
--output DP1-1 --auto
xrandr: Configure crtc 0 failed</pre>
