After installing LEAP 42.2 beta2 from an USB stick, my ASUS RX480 was not
detected and KDE ran in 1024x768 resolution on my 1920x1080 display.

After upgrading kernel and X11 the monitor used native resolution and MESA 3D
was working.

So, kernel and MESA(4.4.21 and 11.0.8) are quite old and do not support the AMD
graphics cards[1] released this summer. Are there any plans to backport that
AMDGPU support to 4.4.21?
Or, are you recommending future LEAP 42.2 users to directly switch to the
Kernel:/stable and X11:/XOrg repositories?
