Disabling or re-Enabling the Gnome 3 user list in Fedora 22

Yet another variation on the long search for a way to hide my system's user list from casual crackers who might get access to the device. All previous posts on the topic of disabling or re-enabling Gnome 3's login screen's user list are obsolete as of Fedora 22. The Red Hat Enterprise Linux 7 Desktop Migration and Administration Guide addresses this here. Those instructions are mildly incomplete, at least for Fedora 22. Here is the complete recipe: 1. Create /etc/dconf/profile/gdm with the following contents: [code language="bash" gutter="false"] user-db:user system-db:gdm file-db:/usr/share/gdm/greeter-dconf-defaults [/code] 2. Create /etc/dconf/db/gdm.d/00-login-screen with these contents: [code language="bash" gutter="false"] [org/gnome/login-screen] disable-user-list=true [/code] 3. This is important: Delete /etc/dconf/db/gdm. 4. As root run "dconf update". 5. Restart gdm with "systemctl restart gdm". To reverse the effect edit 00-login-screen and replace "true" with "false" and then repeat steps 3, 4 and 5. If you take these steps and the changes have no effect, try rebooting. Should that not do it, su to root and delete /var/lib/gdm/.config/dconf/user.
