Hey Joachim, Could you supply us with some more information, like: - The output of `echo $DISPLAY` - Verbose output of you're display manager - The version of the software you are using(Gnome, xorg and gdm) Can you also answer a few extra questions such as: - Are you running the program from a vtty or a terminal inside your desktop environment(If yes what terminal are you using?) - Can you supply us with a list of the applications that do not work and could you also try running them trough `gnome-do`? I will await your answer.
