Gnome 45 refuse to start Wayland

Help
1

Hello, so my problem is simple gnome is launching x11 window system instead of wayland this make no sense… here is the content of my “journalctl” : error w - Pastebin.com

What i tried to fix the issue ? First i thought mutter was causing the issue : GNOME - NixOS Wiki so i removed mutter in my config.nix but it’s still doesn’t work… For more information i’m using the kernel hardened maybe the issue is coming from this ? By the way i’m on the unstable channel

Here is my config for gnome :

services.xserver = {
enable = true;
displayManager = {
gdm.enable = true;
defaultSession = “gnome”;
gdm.wayland = true;
autoLogin = { enable = true; user = “user”; };
};
desktopManager.gnome.enable = true;
libinput = {
enable = true;
};
};

Thanks in advance for any help :slight_smile:

After this i checked the gdm.service and i see it’s masked ?.. user@user ~ [4]> sudo systemctl status gdm
○ gdm.service
Loaded: masked (Reason: Unit gdm.service is masked.)
Active: inactive (dead)
