It fails with all programs.
The problem is that the DISPLAY variable is not getting set. After
logging into both machines with ssh -X machine_name
-----------------------------
[EMAIL PROTECTED]:~$ echo $DISPLAY
localhost:10.0 ** Ubuntu machine where everything works
-----------------------------
[EMAIL PROTECTED]:~$ echo $DISPLAY
** Xubuntu machine where nothing works
[EMAIL PROTECTED]:~$
------------------------------
The /etc/ssh/sshd_config files are the same in both machines.
I don't know how DISPLAY gets set
