i'm still running suse 10.2, when i set it up i made some notes so i thought i'd post some here. if you run a program as root on the default 10.2 install it doesn't use your normal theme, you can fix that like this -
make root apps use your theme -
sudo ln -s /home/USERNAME/.themes /root/.themes
you can make root apps use your icons too, but i don't do that because i like root to look different so i don't forget i'm using it. but, here's how to do it -
sudo ln -s /home/USERNAME/.icons /root/.icons
so, this is how nautilus looks before it uses my theme -
this is it using my theme (i didn't link me icons, that's so it's easy to tell the difference between root and a normal user) -
and this is how natuilus looks normally in user mode.
