Hi, In former times it was possible to disable the user list of GDM by setting /apps/gdm/simple-greeter/disableuserlist to 'true' with the help of gconf-editor. The dconf-editor doesn't offer this option. How do I disable the user list in GDM 3.6.2?
cat > /etc/dconf/db/gdm.d/01-mysettings <<EOF
[org/gnome/login-screen]
banner-message-enable=true
banner-message-text='WARNING!!! You have accessed a private network.\nUNAUTHORIZED ACCESS IS PROHIBITED BY LAW\nViolators may be prosecuted to the full extend of the law.\nYour access to this network may be monitored and recorded for quality\nassurance, security, performance, and maintenance purposes.'
disable-restart-buttons=true
disable-user-list=true
EOF
rm /etc/dconf/db/gdm
dconf update
Recompiling the /etc/dconf/db/gdm file such as: dconf compile gdm gdm.d recreates the file, that otherwise is left untouched by dconf update if it already exists. The solution above works around this by deleting it. This may be helful if you are scripting this procedure. Worked for me with Fedora 23.
Shouldn't the title here be changed to "UNSOLVED"?
Has anyone had any success getting the warning banner to work in Fedora 20 Beta using the file (/etc/dconf/db/gdm.d/01-mysettings) method ? I am able to disable the user list, but cannot seem to get the banner text to display.
On my Fedora XFCE spin, I was able to remove users from the login screen by changing their login shell to /sbin/nologin. (It is a property of the user account in Users & Groups.)
UPDATE:
apparently this isn't working at the moment. I will dig to find how and update this answer as soon as I get a better one!
To view the current status run
gsettings get org.gnome.login-screen disable-user-list
and the output should be "false".
To disable run the following command
gsettings set org.gnome.login-screen disable-user-list true
Then logout and see if it works.
