I think I know what it was for me. I installed Gnome-settings manager based on a recent post. I did not like it and purged it from the APT package manager. However, for whatever reason, GDM remained as a default in some capacity.
Yes, it’s packaged and used on laptops. It’s not used on phones.
Check /var/log/apt/.

checked the apt and dpkg logs no gdm mention so not sure. I installed libglib2.0 but it doesnt list that it installed gdm3.
Is it safe to remove gdm3 from the L5?
I think Gnome-Tweaks installed it.
huh i don’t see the gdm3 in the dependency list though https://packages.debian.org/bullseye/gnome-tweaks, how did you figure out that is what installed gdm3?
Oh wait it is through the dependency https://packages.debian.org/bullseye/gnome-shell-extension-prefs with https://packages.debian.org/bullseye/gnome-shell dependency which requires gdm3 package, good catch my friend!
Oddly enough gnome-tweaks works just fine without gdm3! Lesson learned here since a lot or most users install gnome-tweaks on their L5 is to then un-install gdm3.
