I’m just back on Gnome in the past couple of days, after being away from it for awhile.
I have really never liked GDM much, and in particular I’ve really disliked the “lock shield”.
I was pleasantly surprised at first boot after a fresh install, to see such a refreshing looking login screen, and was similarly happy to see the lock/unlock screen. Had I been doing the setup myself I would never have thought to step outside of GDM for gnome.
The nvidia issues almost had me changing to gdm anyway, but I seem to have fixed them with the advice from https://forum.antergos.com/topic/2235/locking-and-switching-user-problems/11
Anyhow, that’s it. Thanks!
