When I set a solid color as desktop background (like black), which I like far better, then the login screen shows the default purplish picture (warty-final-ubuntu.png). How to I make it also show a simple black screen?
Btw, I educated myself about lightdm settings and access rights to pictures in /usr/share/backgrounds, so I specifically ask for an answer that does not involve any picture files, since I want a simple, single color, no gradient.
In response to first comment, I think I still need more specific knowledge about lightdm.
First of all, im using Ubuntu 14.04 and the configuration files I am looking at are in this directory:
Is it supposed to work in a way that all these files are always read, when lightdm starts (maybe in lexical order)? Is there something else I would have to look at? I specifically tried setting this:
but it had no effect whatsoever (still showing warty-final-ubuntu.png), that's why I came here.
Edit: @kenn Actually, in my case that file does not exist.
