Hello,

I'm using gnome 3.0 from gnome overlay and I want to exclude some users from gdm login list.
Let's name user1 and user2 unwanted users, from now on.
What I already did:
1. I tried via recomanded way. In /etc/gdm/custom.conf:

Code: Select all

[greeter]
Exclude=user1, user2

2. I tried to eliminate them directly from /usr/share/gdm/gdm.schemas

Code: Select all

    <schema>
      <key>greeter/Exclude</key>
      <signature>s</signature>
      <default>bin,root,daemon,adm,lp,sync,shutdown,halt,mail,news,uucp,operator,nobody,nobody4,noaccess,postgres,pvm,rpm,nfsnobody,pcap,user1,user2</default>
    </schema>

3.

Code: Select all

usermod -s /sbin/nologin user1
usermod -s /sbin/nologin user2

But... the users are still in the list.
I have no idea what else to try to acomplish my goal. Any hints, please ?

Hi,

Sorry, I can't help with this. I was interested if you got anywhere solving it. I have a similar issue and actually being able to make changes to the gdm3 config at all. E.g. I wanted to change the background (in addition to excluding some users)

I can't remove any users from gdm list. I patiently decided to wait for gnome 3.2.

I will stick with gdm3. A bit strange it takes so long getting an updated gsm. Most other gnome components get updated all the time. Haven't actually had any problems with this one, just want to be able to configure the damn thing...

Hi, still there Costel?

I have solved both problems finally. The answer is on the arch forum in this post.

Changing the background using gsettings, as in the first part of that post, didn't work for me (gdm-3.0.4). The second version worked (copying these things into the /etc/gdm/autostart/LoginWindow). I could then change the background and many other settings.

The part of hiding some users, I solved a different route. I remember seeing somewhere that users with a UID number below 500 will not be shown login list. So I changed the user I wanted to hide to 499, and finally it disappeared from the login. I found this on how to do that: http://it.toolbox.com/blogs/locutus/how ... -gid-26368 Also remember to change the owner of that users files (e.g. using chown). I had to run groupmod before usermod (usermod throws an error if the group doesn't exist.

Hi,

I was facing the same problem, and was not able to remove only some users. Nevertheless I found out here a solution to remove the user list.
I copy it in case someone would be interested :

As root, create and edit a file e.g. "/etc/dconf/db/gdm.d/01-local-settings". Minimally, it should contain:

###
# local system-wide customizations

[org/gnome/login-screen]
disable-user-list=true
###

and then run "dconf update".

Hope this help
