IIRC, it’s not entirely deterministic (but it fails most of the time). I don’t have any leads on this yet. > Since I prefer to use Wayland, and would rather not have a separate Xorg > session running that I never use, this means that currently I must avoid > using 'gdm-service' entirely. Yes. The service does not currently support Wayland. I believe that Wayland support will require a few modifications to GDM itself. At least, we ended up modifying the X session startup a little bit, and I would guess that the Wayland session startup would need similar changes. > Note that this is on a system running fairly recent 'master', but before > 'staging' was merged.
