<pre>Everything worked fine on 4.18 and 4.19 was ok but fickle. As of 4.20, GNOME
shell won't recognize the external display at all. I plug it in and the main
laptop screen goes black and the monitor continues to be in power-save mode.
If I unplug, everything goes back to normal on my laptop. Maybe the link just
never trains?
I've tried with two different Dell monitors with two different USB-C HDMI
adapters (Cabel Matters and a Kensington dock) and with and without my KVM
switch. None of it makes a difference.
Hardware: Dell XPS 13 9360 (KBL-R)
Kernel: 4.19.13 is okish, 4.20.15 and 5.0.4 are broken. All kernels are Fedora
builds
Userspace: Fedora 29 with GNOME Wayland, everything updated</pre>
