Hi there!

I used the GDM Wayland option in Garuda Assistant to enable wayland, and it works, but only after logging out and logging back in.

On the first login (from boot), there are only two options for sessions when logging in with GDM, Gnome, and Gnome classic. Logging in brings me to an X11 session (I've checked with loginctl show-session number -p Type), where all extensions have been disabled, including reverting the theme back to Gnome's white default.

After logging back out, GDM starts again and this time will have three options for choosing a session, Gnome, Gnome Classic, and Gnome on Xorg. Logging in with the Gnome option brings me to a Wayland session (checked with loginctl again) where all of the extensions are properly enabled and everything works fine.

I've tried enabling KMS Early Start, which appeared to already be in /etc/mkinitcpio.conf. I've also tried disabling gdm and launching a graphical session with the following, XDG_SESSION_TYPE=wayland dbus-run-session gnome-session, which worked perfectly and took me directly to a wayland session, which leads me to believe its an issue with gdm.

Here is the output of my /etc/gdm/custom.conf:

# GDM configuration storage

[daemon]
AutomaticLoginEnable=False
# Uncomment the line below to force the login screen to use Xorg
#WaylandEnable=false
DefaultSession=gnome-xorg.desktop

[security]

[xdmcp]

[chooser]

[debug]
# Uncomment the line below to turn on debugging
#Enable=true

Any help would be much appreciated, thank you!

Remove this line.

Thank you for the reply!

I've removed the line, but I'm still experiencing the same behavior as before.

That's strange :thinking:
I am not the Gnome guy anyway :sweat_smile:
Maybe more experienced gnome users would help.

I'll need to have a look.
