Bug 847580 – gnome-base/gdm-42.0: gdm fails to start at boot when autologin is enabled

• Product: Gentoo Linux
• Status: RESOLVED WORKSFORME

[Description Pacho Ramos 2022-05-26 11:00:58 UTC]

If I enable autologin, gdm will fail to start at boot (also the system will be unusable as systemd will keep restarting it and failing forever :S

The failing start is due to this error when trying to start my X session:
(EE) NVIDIA(GPU-0): Failed to acquire modesetting permission

But that error only happens at boot time, if I disable gdm.service and later start it with systemctl start gdm it works fine. Also works fine if I disable autologin

I wondered if maybe we should do like Arch and package a snapshot including the round of fixes they added for nvidia setups:

https://gitlab.gnome.org/GNOME/gdm/-/commits/main

I wonder why upstream didn't open a 42.0 branch :/

We don't have that vt.handoff handling... but I had:

Dead symlinks for tty2 to 6... I removed them (only kept the tty1 one pointing to the right location)... and the problem got fixed finally :O
