This is the issue.. Using sudo on a GUI program. It is stripping DISPLAY environmnent variable. You should avoid to run graphical program as root, but if you really must, either use "xdg-su -c program" or using "sudo -E" but the second one might cause a lot of issues with interaction with other desktop components (dbus socket, etc..) -- Frederic Crozat Enterprise Desktop Release Manager SUSE -- To unsubscribe, e-mail: [email protected] To contact the owner, e-mail: [email protected]
