dmesg
4.14.14-300.fc27.x86_64 (Fedora 27).
Thinkpad X1 Carbon (5th gen). Using GNOME on Wayland.
When I plug in a monitor to the HDMI port... nothing happens. It does not show
up in the display panel, and is not lit up.
Thunderbolt/USB-C port through USB-C->HDMI adapter also does not light up
display.
