Using Ubuntu 10.04.1 Desktop (Latest)
After the boot process, GDM shows the graphical login screen along with a list of users that can log in. Clicking a name will ask for its password.
I would like to modify that list and show only a restricted list of users.
(i.e., the other users may still be able to log in via the terminal access or 'su' - after Control-F4 for instance - but their login name should not appear on the Gnome login page).
Please let me know where to find that file(?). I would like to perform the change from the terminal window (not the graphical environment), after a ssh for instance.
