Login screen users - hide - ?

[lejeczek]

Hi guys.

Is it possible to hide somehow a user from Login screen, so 
such user/account would not show up in that list of users?

many thanks, L.

Probably depends on the login manager. I use sddm and have
this in /etc/sddm.conf

# Comma-separated list of users that should not be listed
HideUsers=backup

In my case "backup" is a rsync only user I have for doing backups.

I'd guess other login managers have similar features, though perhaps
configured entirely differently.

Gnome/gdm has this:
-> $ dconf read /org/gnome/login-screen/disable-user-list
true

so not selectively but choose users all, yet that too does 
not seem to work.

thanks, L.

I concur.  Long ago, I'd used one with very old Gnome that did allow
you to hide some users, then they took that feature away.  I don't know
if they put it back, because I use Mate, now, and I haven't tried to
see if it hides some users.

Some installations provider a configuration app for modifying the login
screen, some do not.  At times I'd done that kind of thing by adjusting
a config file by hand.

In the past various features have come and then died, like being able
to put user face pictures in the list of users on the login screen (the
feature still being there, but didn't actually work).  Sometimes I'd
removed the list of users, and just had a login screen where you typed
your username, then typed your password.

You don't have to use the default login manager for your desktop. 
Though you may find your desktop made use of some features that only it
set triggered.
