Well thats not good.
I wonder whats messed up.
OK... double check you dont have anything weird forcing some config in
(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
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/
