I installed KDE 6 from the ISO (Plasma Desktop, 64-bit Intel/AMD). By default it installed open source Nouveau but I followed this wiki and installed non-free Nvidia drivers.
But the thing is the KDE Login screen / SDDM is badly freezing up. The mouse barely moves. I can type in the password but the cursor barely moves. How to make the login screen work normally?
This is my configuration.nix

Ok thanks.
Can you pleas try follwing:
services.displayManager.sddm.wayland.enable = false;
And if that does not work try this setting with true.
