Dovrei utilizzare un'applicazione java.
Quando la lancio mi risponde :
java.awt.HeadlessException:
No X11 DISPLAY variable was set, but this program performed an operation which requires it.
Allora ho provato con
export DISPLAY=:0.0
A questo punto l'errore si è modificato in
Invalid MIT-MAGIC-COOKIE-1 keyException in thread "main" java.lang.InternalError: Can't connect to X11 window server using ':0.0' as the value of the DISPLAY variable.
Cosa posso fare ?
