Change the Background of Gnome 3 GDM Login Screen

We cannot change the theme of Login screen of Gnome 3 GDM. We can only change the background image of the login screen. If you change that frequently then you will get a fresh feel of the operating system.

I tried this on Fedora 15 and worked well

GDM Customization

# su - gdm -s /bin/bash
$ dbus-launch

This command will print DBUS_SESSION_BUS_ADDRESS and DBUS_SESSION_BUS_PID. We need to export them

$ export DBUS_SESSION_BUS_ADDRESS=unix:abstract=/tmp/dbus-Jb433gMQHS,guid=fc14d4bf3d000e38276a5a2200000d38
$ export DBUS_SESSION_BUS_PID=4283

Check to see if dconf-service is running and if not, start it like this

$ /usr/lib/dconf/dconf-service &

Wallpaper

$ GSETTINGS_BACKEND=dconf gsettings get org.gnome.desktop.background picture-uri
$ GSETTINGS_BACKEND=dconf gsettings set org.gnome.desktop.background picture-uri "file:///usr/share/backgrounds/gnome/SundownDunes.jpg"

You will need to point to a file where the gdm user has permission to read, not in your home directory.

Start program automatically after login to GNOME 3

You can specify which programs to start automatically after login using the gnome-session-properties tool, which is a part of the gnome-session package.

$ gnome-session-properties

Turning off the sound

$ GSETTINGS_BACKEND=dconf gsettings set org.gnome.desktop.sound event-sounds false

Start program automatically after login to GNOME 3

You can specify which programs to start automatically after login using the gnome-session-properties tool, which is a part of the gnome-session package.

$ gnome-session-properties

There is lot more tweaks at Arch Linux Wiki about gnome 3.
