How do I change the wallpaper in LightDM?
I have been trying to find an answer to this, but it doesn't seem to be possible to find someone who has had a similar issue, although I find that hard to believe. Nonetheless, here's the issue.
When I work on my computer, I like having a picture of my better half on the screen, so that every now and then, when I take a short break, I can look at her, smile, and go back to work. But when I lock the screen, that picture remains the background picture, and quite frankly, I wouldn't appreciate other people looking at her when I'm not on the PC.
Any pointers into the right direction would be greatly appreciated! It's 12.10 btw.
