Hello,
I am trying to start remotely an application with a GUI (for example xclock)
and I am getting the error 'Connection to ":0.0" refused by server'. I have
the following cases:
laptop1 and laptop2 with ubuntu 7.10
Case A.
- login to laptop1
- login to laptop2
- open terminal window on laptop1 and type:
...laptop1:~$ ssh laptop2
...laptop2:~$ export DISPLAY=:0.0
...laptop2:~$ xclock
- result: xclock window appears on laptop2 :)
Case B.
- login to laptop1
- DO NOT login to laptop2 (remain at gdm "login screen")
- open terminal window on laptop1 and type:
...laptop1:~$ ssh laptop2
...laptop2:~$ export DISPLAY=:0.0
...laptop2:~$ xclock
- result:
"Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified
Error: Can't open display: :0.0"
The reason I am posting this here is because we had the same problem when
starting eqPly on our lab computers. At that moment we just took the first
solution: login and then xhost + ... But Stefan told us that on the cluster
used by the Equalizer team they managed somehow to display the eqPly window
over the login screen. So there must be a way to set/tell X Server to accept
the connection to :0.0 . My question is HOW ?
Thanks in advance.
Regards,
Anca
P.S.: I'm happy to see that the PBuffers came already with version 0.5 :D
