Oh right, you don't have Xorg, Forgot KDE uses Wayland now...
Well, tough luck buddy, don't know the command for starting wayland.
Try to fix your broken display manager, see if it's running, then if it's not running run it and see if it's started and if it's giving errors:
sudo systemctl status sddm.service
sudo systemctl start sddm.service
sudo systemctl status sddm.service
