Hello,
I have a laptop that I use exclusively for work. When I bring it to the office, I plug a second screen in, via the HDMI port directly on the laptop itself, and I try to plug in a third screen via the HDMI port that is on the USB-C hub that I use.
That third screen is never detected, and never turned on when plugged via the hub. It works well if I plug it in directly via the HDMI port on the laptop, so it is neither the screen or the cable. I also tried with other USB-C hubs and it does not work either, so it is unlikely that the hub itself is at fault.

After reading how to generate the report log file, I read that I should start the X server with specific parameters. So I tried, and this is what I got:
$ startx -- -logverbose 6
/usr/lib/xorg/Xorg.wrap: Only console users are allowed to run the X server
^Cxinit: giving up
xinit: unable to connect to X server: Connection refused
xinit: unexpected signal 2
Couldn't get a file descriptor referring to the console.
So I tried again with sudo:
$ sudo startx -- -logverbose 6
