Today I did a clean install for ubuntu 11.04. Having seen the power of Gnome 3 (with Fedora) I installed it right away. Some minor problem arose and I had to deinstall accessibility themes and install the "standard" gnome themes.
However there is one more problem and I've added a screen shot to show the problem. As you can see, the gnome desktop seems pretty cool but however the tweak tool doesn't show properly (empathy and other apps neither).
Besides the fact that the themes don't properly show in this screen I also get the error "User Theme extension not enabled" now I get the feeling these problems are related, but how do I fix it?
If anyone can give any idea's I'd be very grateful, I've searched everywhere but as far as I know I seem to be the only one with this problem. I would love to take the full advantage of a Gnome 3 desktop but this is getting to be a big "bump" in the road.
