Anyone know how to do $SUBJECT? I've tried running both gnome-control- center and dconf as the gdm user, but neither one had any effect.

TIA

Hi,

Best way to-do this and one that is reversible if needed.

• Open terminal.
• Do: 'cd /usr/share/gnome-shell/theme'
• Do: 'sudo cp -f noise-texture.png noise-texture.png.orig'
• Pick a wallpaper that is 'png' and the same resolution as your screen.
• Do: 'sudo cp -f /path_to/my_image.png noise-texture.png'

You may need to experiment with the size of the image to match your resolution.

To reverse the changes:

• Do: 'cd /usr/share/gnome-shell/theme'
• Do: 'sudo cp -f noise-texture.png.orig noise-texture.png'
• Do: 'sudo rm -f noise-texture.png.orig'

Regards

Phil

Side note:

Why I say same resolution as screen is that the noise-texture.png that is used is smaller than the screen and then tiled. If you wished, you could create a funky smaller patterned image that will tile to make for a more consistent background. Hmm... something like a (hint hint) darker blue CentOS inspired look rather than the grey - god who chose drab grey. :-(

Regards

Phil

You probably want to read over ->

and

Essentially you just need to jam the right voodoo in a local dconf config file and 'dconf update'.

Actually, the first paragraph at your first link says:

.... Note that the login screen background image cannot be customized.

Pretty unbelievable. Hopefully kdm, lightdm, sddm, or even xdm will pop up in EPEL soon.

Searching on Google turns up this:

http://www.webupd8.org/2012/11/how-to-customize-gdm-36-login-lock.html

and states that: ==> You can manually change the GDM 3.6 grey background image. The image used by default is located under /usr/share/gnome-shell/theme/ and is called noise-texture.png.

Like its name says, the grey image used by GDM 3.6 is a pattern, but you don't have to use a pattern and a regular wallpaper image works too. To change it, open Nautilus [or Dolphin file manager] as root:

gksu "nautilus --no-desktop /usr/share/gnome-shell/theme/"

then make a backup of the original "noise-texture.png" image and replace it with the image you want to use as a background for the GDM 3.6 login / lock screen. <==
