Recently, I wanted to change my background login image on Manjaro, but no parameters like changing the desktop background.
It's already been several times that I reinstall a Manjaro instance, and each time I forget how to do it. So here is a post of how I did it. You'll see it's very, very easy.
Open your terminal and get SUDO perms, you can copy your beautiful photo to another folder like
Documents/ with the command
Help ? How to use cp command
With the terminal,
sudo nano /etc/lightdm/lightdm-gtk-greeter.conf
You have something that looks like this :
[greeter] background = /usr/share/backgrounds/illyria-default-lockscreen.jpg user-background = false font-name = Cantarell Bold 12 xft-antialias = true icon-theme-name = Adapta-Papirus-Maia screensaver-timeout = 60 theme-name = Matcha-sea cursor-theme-name = xcursor-breeze show-clock = false default-user-image = #manjaro xft-hintstyle = hintfull position = 50%,center 57%,center clock-format = panel-position = bottom indicators = ~host;~spacer;~clock;~spacer;~language;~session;~a11y;~power hide-user-image = true
Edit the background line with your file, and it's done !
