Changing GDM background

The Beefy Miracle wallpaper is not very pleasing to the eye so I looked into changing GDM background on Fedora 17 Linux. In order to accomplish this feat, we can use gdm3setup.

To get gdm3setup, clone its git repository:

git clone

Then run script as root to install. It will install a shortcut (.desktop file) so the application is accessible from the Applications list as GDM3 Settings.

Apart from changing the wallpaper, it offers a few more options for customization of both GDM and Gnome Shell, like cursor theme, GTK theme, logo, etc.

On Fedora 17, 64-bit. I tried following your how-to and the application installed OK. However, when I chose my settings and hit "OK", my desktop locked up completely. On reboot, I can't access my desktop any more - at the point where the GDM login screen should appear, I just get a flash of my wallpaper and then the GNOME "Oh No! Something went wrong" message... and I can't get any further.

I've gone to the terminal and tried switching to KDM, but same problem. I checked out the /home/(username)/gdm3setup directory, but theres no "uninstall" script I can run. I've tried removing /usr/bin/gdm3setup.bin... still no joy.

Any ideas?

@itsjustarumour: Hi. There is no uninstall script but it should be relatively easy to undo the installation by reversing the commands from the Below are the contents of the install script:

cd po
cd ..

install --mode=755 -D /usr/bin/
install --mode=755 -D /usr/bin/
install --mode=755 -D start-gdm3setup-daemon /usr/bin/
install --mode=755 -D /usr/bin/
install --mode=755 -D /usr/bin/
install --mode=755 -D /usr/bin/
install -D gdm3setup.desktop /usr/share/applications/
install -D apps.nano77.gdm3setup.service /usr/share/dbus-1/system-services/
install -D apps.nano77.gdm3setup.service /usr/share/dbus-1/services/
install -D apps.nano77.gdm3setup.conf /etc/dbus-1/system.d/
install -D apps.nano77.gdm3setup.policy /usr/share/polkit-1/actions/
install -D gdm3setup.ui /usr/share/gdm3setup/ui/gdm3setup.ui
cp -r locale /usr/share/


However, removing gdm3setup might not be the solution to the issue you are having. You have already modified a certain setting that is now crashing Gnome.
What happens if you log in to a console terminal (Ctrl+Alt+F2 or F3...) and try to run 'startx'?

If you want an installable package, have a look at file in the cloned repository. There is a way to package gdm3setup into a package.
However, I did not do that.

Hi Alen,

OK, many thanks for the help - all working now! :-)

Keep up the good work, I've found your other posts on Fedora 17 64-bit to be very useful, and I'm sure they're helpful for many other peopole too.
