Revision history [back]

I always use ssh to connect to my remote pc running ROS.

I suppose that: - you are using -X flag starting shh ($> ssh -X user@host) to forward X - XForwarding is enabled on your remote PC (X11Forwarding yes in /etc/ssh/sshd_config)

Try to type

echo $DISPLAY

probably it will return nothing and this should be the cause of failed string parsing.
