<div>
<pre>On my Dell XPS 9560, and Linus post-5.3 git tree, my Dell U3415W is no longer
driven from X. The screen goes into standby, and attempting to use it shows:
$ xrandr --output DP-1-2-8 --above eDP-1 --auto
xrandr: cannot find crtc for output DP-1-2-8
Note that the screen lights up during boot, as it always did. Once lightdm is
started, the screen turns off. When I shut the machine down and X terminates,
the screen lights back up.
I will be adding attachments shortly.</pre>
