There are two general ways I'm aware of to test the other display driver option:

1-uninstall xf86-video-amdgpu (if installed; or amdgpu-install_22.20.50205-1_all.deb
if that's where your amdgpu_drv.so came from), then restart X

2-create /etc/X11/xorg.conf.d/50-device.conf containing:

	Section "Device"
	    Identifier "DefaultDevice"
		Driver	"modesetting"
	EndSection

then restart X.

If the monitor's EDID is a problem, create /etc/X11/xorg.conf.d/50-device.conf
containing the same specifications you would feed GTF or CVT to create a specific
modeline, so that Xorg can do the same automatically for any similar monitor you
might wish to connect:

	Section "Monitor"
	    Identifier "DefaultMonitor"
		HorizSync	29-94
		VertRefresh	49-86
		Option	"PreferredMode"	"1920x1080"
	EndSection

Substitute the values from your monitor's docs for the HS & VR values in this template.
