If you cannot explicitly specify a display number, I would say, use the '-displayfd' X server option [1], for example: xinit -- -displayfd 3 3>~/.display export DISPLAY=:`cat ~/.display` Unfortunately, while this works with xinit, it seems there are bugs not noticed until now which prevents this from working correctly with startx (startx ends up supplying both :display and -displayfd, which doesn't work correctly, and the xauthority generated may reference the wrong display number, leaving clients unable to connect) [1] http://x.cygwin.com/docs/ug/using-terminal-server.html -- Jon TURNEY Volunteer Cygwin/X X Server maintainer -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
