I've got a theme set up for my root account in Gnome, but when I'm running as a normal user and run an app while logged in using 'su' the root app doesn't use either my theme or the root theme. Any idea how to get the root theme to show up?

that's because you're still "acting" as the normal user, for instance the $USER env-variable is still the normal user. Use 'su -' instead to fully become root.

What happens if you run an application with gsudo?

When I use "su -" intead of just "su" got this message when I tried to run an app: Gtk-WARNING **: cannot open display:

so I did this:

export DISPLAY=:0.0

and that fixed that problem so it's at least running, but it's still not using the root's theme.
