[SOLVED] GDM Wayland not working at login

Hello, I'm working on latest Arch Linux version with GNOME 44.1 and GDM as Display Manager.

On my system I set "/etc/gdm/custom.conf" as the following for having Xorg as default:

# GDM configuration storage

[daemon]
AutomaticLoginEnable=False
WaylandEnable=false
# Uncomment the line below to force the login screen to use Xorg

In this manner, the "gear" icon on GDM at login time is not shown. Then, I decided to re-enable again Wayland and I changed "custom.conf" as:

[daemon]
AutomaticLoginEnable=False
WaylandEnable=true
# Uncomment the line below to force the login screen to use Xorg

In this manner, when I reboot, I see again the "gear" icon, I set "GNOME on Wayland" and when I type my password and I press enter, it returns back to the username view on GDM instead of login.

Why is it happening? Is a GDM issue?

Re: [SOLVED] GDM Wayland not working at login

when I type my password and I press enter, it returns back to the username view on GDM instead of login.

Means the session fails - most likely not a GDM issue.
Check the system journal, the usual suspects are 3rd party extensions which usually break w/ every gnome update.

Re: [SOLVED] GDM Wayland not working at login

The weird behavior is still there. I just add I'm working on a VM on VMware. From the journal, if I grep "gdm" and "wayland", I have the following:

░░ A start job for unit gdm.service has begun execution.

Re: [SOLVED] GDM Wayland not working at login

I solved. The problem was in "/usr/bin/gnome-session". In practice, my $SHELL variable was /usr/bin/bash, and it is not inside "/etc/shells", so I added it in this file, then reboot and it has been fixed.
