I am using UbuntuTweak on Ubuntu 12.10. I have installed a very nice icon theme. It doesn't appear to work when I select it from Tweak, but as soon as I start e.g. Nautilus running as root, I can see it has all the new icons.
So if I start Nautilus 2 times, once with my user and once with root, they look differently.
Does anyone have any idea about how I could fix this?
