<pre>Kernel mode setting seems to detect resolutions not supported by the screen, so
you may be stuck in out of range screen error while using certain applications.
Later I tested the installation of xorg-x11-drv-amdgpu Fedora package, and
indeed the problem disappeared
Note: in both tests the machine has been started with grub command line
argument amdgpu.dc=0 due bugreport
