Re: SDDM/Xorg Issues

Looking at your logs, my impression is, your system doesn´t load the amdgpu kernel module and does not load the amdgpu Xorg driver.
Does lsmod | grep amdgpu give any output? If not, the kernel module is not loaded at all.

I would try the following:

Go to /etc/X11/xorg.conf.d/
Is there a file with "device" in its name, like 50-device.conf?

If yes:
look at the line with Driver at the beginning and make sure it looks like this, with the quotation marks.
Driver "amdgpu"

If there is no such file with "device" in its name, create it, call it e.g. amd.conf with this content:

Section "Device"
  Identifier "Card0"
  Driver "amdgpu"
EndSection

The above thing makes sure, Xorg loads the amdgpu driver.

Now manually load the amdgpu kernel driver:

modprobe amdgpu dc=1

Now try to start X.
