Good Morning, I tried to install from the Travis build on to Fedora 28_64.
This feels related to #63 , but I'm not smart enough to know how.

EDIT2: Using X11 rather than Wayland, while having Secure boot disabled did the trick. This should probably be added to the docs? Is there an easier way and I got lucky here?

Any thoughts or more info I can provide?

Result of journalctl -f -n 0 is:

I don't have a lot of additional information, but I wanted to confirm that my experience mirrored that of the original poster (clham). I started off on Fedora 28 with KDE (the spin, not added later) and X11 (Wayland isn't quite ready to go with KDE so that was never in the picture) on a recent Dell XPS 13 9370.

Disabling Secure Boot in BIOS/UEFI allowed this to work.

Usually the error on modprobe evdi with Secure Boot enabled should be modprobe: ERROR: could not insert 'evdi': Required key not available, and not Operation not permitted. That happens most likely when the user does not have permission to use modprobe.

If you still want to benefit from Secure Boot, you will have to follow steps to enroll a MOK (Machine Owner's Key) into your chain of trust. You can follow my comment here #48 (comment). For a more high-level explanation I have an answer on askubuntu that is totally transposable to Fedora: https://askubuntu.com/a/797442/12049

just following up on my post from above. I disabled wayland from the custom.conf file in /etc/gdm3/

WaylandEnable=false

and now it works.

I'll mark this as closed since everyone here seems to have worked this out.

I had the same issue, my third monitoring didn't work. I was able to make it works thanks to the previously mentioned link. I'd like to give a shout-out to everyone who helped here
