gentoo-change-gdm-background

This script automates the process of setting an image or color in GNOME Display Manager 44 background on Arch/Gentoo Linux

Warning

I've let most of the README intact, however I could not test it on Arch. I guess it should behave the same... Feel free to open an issue on any problem

This script wont work with older versions of GDM because they have a different way of dealing with gdm settings.

It also won't work if your system is set to a custom gdm3 theme. You will have to reset to the default configuration of gdm3 before using the script.

This tool was made specifically to work with Arch/Gentoo Linux as it now bundles all configuration files inside a .gresource file

If you are going to set an image file that has spaces in its file name or folders, remember to scape them with backslashes.

Installation (Arch)

First, you will need to install with pacman -S glib2 Then, you can download the script with the command below:

wget -O arch-change-gdm-background github.com/Loatchi/gentoo-change-gdm-background/raw/master/gentoo-change-gdm-background

And set it as an executable with chmod +x arch-change-gdm-background

Installation (Gentoo)

Simply use my overlay:

eselect repository enable loatchi
emaint sync -r loatchi
emerge change-gdm-background

Usage

It will be called change-gdm-background but it should work the same either on Gentoo or Arch

Run the script with root privileges such as change-gdm-background /path/to/image.

If you see a message login image sucessfully changed, then, when you restart gdm or reboot your computer, your gdm background should be covered with the image you selected.

You can restore your original gdm theme any time with change-gdm-background --restore.

Change Color

Now you can change that dull grey color to any color you like. Just type change-gdm-background \#yourhexcode and voilá, you changed it. Your color hex format should be of six characters like \#407294 or three characters like \#6ac.

Feel free to see the project gdm-settings. I've translated their 44-support branch patch for this script to work.
