Can confirm that worked with kernel 4.16.7-300 on Fedora 28 Gn=
ome with wayland
and the right boot arguments. However this worked when I had the R9 390
installed alone. When I used both the R9 390 and Rx 550 on the same system,=
the
display plugged on the R9 390 did not work correctly and produced broken UI
elements from time to time. Furthermore UI was very slow on response.
When tried Fedora 28 KDE, SDDM was constantly crashing when it tried to sta=
rt
and stuck on a loop try-to-start->crash->try-to-start.
Kubuntu 18.04 KDE worked, but had the same issues as Fedora 28 Gnome.
So it seems the dpm bug is at last solved despite the other problems that m=
ight
be unrelated to dpm.

if you installed the kernel manually, then try to install the
kernel-modules-extra package of this kernel version as well.
