Well thats not good.
I wonder whats messed up.
Hm.
OK... double check you dont have anything weird forcing some config in
/etc/X11/[xorg.conf.d,mhwd.d]/
(you will probably see something for keyboard .. thats fine)
Lets try to start over.
Lets remove the prime profile.
sudo mhwd -r video-hybrid-intel-nvidia-440xx-prime
And reinstall video-linux
sudo mhwd -f -i pci video-linux
And make sure to use modesetting
sudo mhwd -i pci video-modesetting
Then reinstall the prime profile
sudo mhwd -i pci video-hybrid-intel-nvidia-440xx-prime
(reboot)
Note - we prefer text here whenever possible. It saves bandwidth, is searchable, and is easier to read.
Just copy/paste here, highlight, and use the </>
code button to format it.
Note2 - if that still doesnt work we might want to look at SDDM:
cat /etc/sddm.conf && echo && ls /etc/sddm.conf.d/
