Thanks.

I want to start an X server in the background, with no visible
clients, if it's not already running, whenever I launch a mintty
session. X should continue to run even if the mintty session that
started it is closed.

Currently I have the following in my .bash_profile

   ps -ef|grep -q XWin || nohup setsid startxwin 2>startxwin.log&

This now works again after adding "exec sleep infinity" in
.startxwinrc, but I can't help feel my whole approach is a bad hack.
Both nohup and setsid seem to be required. Without setsid the mintty
will hang if I attempt to close it with exit or ^D, and without nohup
the X server terminates whenever the first mintty session is closed.

Is there a cleaner way to accomplish this objective?
