Most recent test was conducted in a similar fashion as before, and the results
are as before.

Two screens connected (via HDMI and DP).

During inital boot, both screens are showing some output.

When reaching gdm, DP-screen goes black.

(xrandr run via ssh-session)

xrandr --output DP2 --mode 1920x1200  makes DP-screen show picture again

xrandr --output HDMI3 --off  disables HDMI-screen, does not affect DP-screen

xrandr --output DP2 --mode 2560x1440  DP-screen goes black

xrandr --output DP2 --mode 1920x1200  DP-screen show picture again


Output from xrandr command:

Screen 0: minimum 8 x 8, current 1920 x 1200, maximum 32767 x 32767
DP1 disconnected (normal left inverted right x axis y axis)
