I tried netrunner, but it was buggy to a degree I am currently not willing to deal with (although I loved its appearance). Is it possible to use the netrunner desktop manager for linux mint 17?
What do you mean exactly by desktop manager?
The thing where you login and choose which DE you want.
We use the lightdm userbar theme for lightdm. You can get the wallpaper from the livesystems /usr/share/wallpapers directory.
