Hello,
ssh sets the DISPLAY variable itself provided that :
- the X11 forwarding is enabled in the remote sshd server :
in /etc/ssh/sshd_config : you must have : X11Forwarding yes
(man sshd_config)
- you start the ssh connection with option -X, or you enable the X11 forwarding in your local /etc/ssh/ssh_config or in your
personal $HOME/.ssh/config setting the option : ForwardX11 yes
(man ssh_config)
Besides, the display syntax is :
:displaynumber
(man Xserver)
Regards
