[SOLVED] GDM doesn't allow me to log into wayland session

I use GNOME and I want to log into wayland session, but wayland requires KMS and with nvidia it's should be manualy enabled. "nvidia-drm.modeset=1" kernel parameter is set, but it seems like KMS is not enabled. GDM doesn't show me the option to log into wayland session. I think that problem is with KMS because it "allows for instant console (tty) switching" and for me it is not instant at all.

That's not KMS by DRM KMS, check

cat /proc/cmdline; lsmod | grep nvidia

You'll also need some nvidia 4xx.xx driver - the 390xx series won't support wayland.

GDM has a udev rule that doesn't really work as designed and will falsely remove the Wayland option even if KMS is enabled. Check https://wiki.archlinux.org/title/GDM#Wa … DIA_driver for how you can disable the rule to offer you Wayland anyway.

That worked, thank you.

Btw, should I change the title of the topic, to what the actual issue was?
