I tried to edit ‘/etc/gdm/custom.conf’ to ‘WaylandEnable=true’, I add ‘MODULES=(nvidia nvidia_modeset nvidia_uvm nvidia_drm)’ to ‘/etc/mkinitcpio.conf’, I add ‘nvidia_drm.modeset=1’ to ‘/etc/default/grub’, I even did sudo ln -s /dev/null /etc/udev/rules.d/61-gdm.rules but nothing change. SDDM does have Wayland option right out of the box. GDM other hand used to work for CachyOS iso installer but as I know, doesn’t work anymore.
