OpenSUSE :: Gtk-WARNING **: Cannot Open Display: :0

For example, the gparted application menu item doesn't work; using it means that there is almost no filesystem support. The only way to get it to work is to open a terminal, run 'su -', and then open it from there.As another example, I tried creating a nautilus script to open files as root with a command like this:

Code:

for uri in $NAUTILUS_SCRIPT_SELECTED_URIS; do
gnomesu -c "gnome-open '$uri'"
done

When I try using it, it just fails. Typing out the command in the terminal gives this (tested on a text file):

Code:

No protocol specified
(gedit:13672): Gtk-WARNING **: cannot open display: :0

I'm pretty sure the problem is that it's granting privileges, but not using the full root environment, or something along those lines.
