I have looked around and could only find this link. I have read it and still don't under stand if I can fix it.
This is the only thing I have found:
I have been trying to install a theme called ZixSaw2 I installed it when I installed Linux. It is in $/usr/share/themes/ZixSaw2 but when I go to gnome theme manager I don't see it in the list... so I click install new theme and install it but I still don't see it in the list.
Any one know a way to fix it?
