I recently installed Arch Linux and have it mostly set up. With many other Linux distributions, there is a tool that is used to configure the look and feel of the login screen. I would like to change the wallpaper used, the date/time format from something like Sat 6:27 PM to 26 Feb 11 18:27, and the refresh rate of the monitor (it's fine when I'm logged in, but not at the login screen).Where can I find these configuration options or (preferably) a GNOME application to allow for me to make these configuration changes?
How do I configure the GNOME gdm login screen?
