Sorry if this has been asked before, but searching the forums for "background image" or "login screen" gave me too many results to be useful.
I would like to change the blue Debian screen that appears while booting LMDE. I liked the previous Debian screens, but not this recent spacefun-splash thingy, it looks like a Christmas card with those red and white stars. So I searched for the images on my computer, and found these files in my /usr/share/images/desktop-base folder:
I think the easiest way to change the screen would be to replace the contents of these files with another image, but isn't there another way? Is there maybe a .cfg file in which those files are referenced or what is the proper way to do this?
Also, do the images have to be in svg format or can I use another format as well?
