When I sue command "sudo gedit xx", it appeas several warning:
gedit:2714): IBUS-WARNING **: The owner of /home/ecomu/.config/ibus/bus is not root! (gedit:2714): Gtk-WARNING **: Calling Inhibit failed: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SessionManager was not provided by any .service files
Actually, the correct command should like this:
gksudo gedit xx
PS: difference between commands "sudo" and "su"...
