dmesg output after trying setting monitor on via xrandr
I'm running latest Debian sid/buster on a Dell XPS 9370 laptop (Kabylake-R
graphics).
I've connected an external DisplayPort monitor to my laptop over USB-C through
a Lindy USB 3.1 Type C Docking Station.
It works fine it seems normally, the DisplayPort is recognized as DP-2-2 in
xrandr.
After suspending the laptop, and wake it up again, the monitor is blank, but
xrandr says it's still connected and a mode is selected. After setting monitor
"--off" and "--auto" again no picture comes up, and I get the errors shown in
the attached dmesg.</pre>
