How to remove users from login window?

[abcuser]

arepaking, this is the same solution that was described on above link, I don't like this solution. It removes whole list and enables login with userid window to enter manually.

I would like ot have a user list (like it is now), but without some users listed on it.

As a workaround, user IDs can be changed to remove users from the login list. Users with IDs under 1000 will not be displayed. I used the following to remove a user from the list:

sudo usermod -u 999 [username]

Not ideal, but it works without much hassle.

Solution in above thread is to remove all users from the list and enable username login window instead.

But I don't want to remove user list. I would just like to remove some users from the list.

This is what I would up doing. I made the gconf-edit changes, but they did not changethe interface, so...

* Consider going in as root...then...
1. System/Administration/Users and Groups
2. On the Advanced tab of user Properties...
3. Change the User ID to a number that is less than 1000.

Far as I can tell, this also takes the user account out of the Users and Groups screen, thus removing your ability to administer the account outside the terminal, but who doesn't use the terminal to admin users anyway?

windowsdown,
I did in the way tristano suggested, so lower ids of users and problem is solved.

Before I have changed the IDs I have checked the IDs of exiting users, to not having any kind of conflict.

Check the users IDs:

cat /etc/passwd | gawk -F: '{print $3, $1}' | sort -n

Lower users IDs (tristano suggestion):

sudo usermod -u 999 [username]

Thanks a lot for help,

I am trying to remove the list of users from the gdm welcome screen

in the configuration editor
/apps/gdm/simple-greeter/disable_user_list

or by typing
sudo -u gdm gconftool-2 --type bool --set /apps/gdm/simple-greeter/disable_user_list 'true'

I have tried making this change by launching the configuration editor from the application menu, from TTY1 before login by launching the editor, and using the above terminal command.

thanks for the help

/apps/gnome-system-tools/users/showall
toggle that and you can see all users

I have two remarks about this thread AKA my $0.02 (USD)

First:

Tristano supplied this exceedingly cool tidbit of hacker knowledge:
As a workaround, user IDs can be changed to remove users from the login list. Users with IDs under 1000 will not be displayed. I used the following to remove a user from the list:

sudo usermod -u 999 [username]

That looks like a winning solution than everything else I have seen in this thread. I was wondering if I could add postgres to the login menu (also if I should - I decided against). Just one fly in the ointment: You would have to track down every blessed file in the system whose UID matches the current UID and change it to the new one.

I see abcuser has already accounted for the concern of duplicating a UID. I just wanted to raise this little warning.

Next, HiImTye suggested to windowsdown:

/apps/gnome-system-tools/users/showall
toggle that and you can see all users

Which tool is that? I have 9.10 and I do not even have an /apps directory, let alone the three directory levels below it. A quick check of Synaptic shows I do indeed have a package named gnome-system-tools installed but is seems to be a directory in /etc; it's only claim to fame (AFAIK) is the file
/etc/gnome-system-tools/users/profiles.

Care to rephrase that command line, Tye? (Gee, that sounded threatening.. )

so still no solution NOT SOLVED I want a login screen just like in 9.04

boot
enter user name
enter password
ta da!!!

I don't want to have a list for everyone to see of all users on my machine. also an advantage of ubuntu no root user enabled, I don't want to enable it because well then everyone now knows my user name.

so I have tried everything I have seen on every forums. any new suggestions will help.

Thanks in advance
