[e-users] X crash when switching

It's not uncommon to run two or more X window managers (WM) or desktop 
environments (DE) such as a main one and testing others, which is what 
I've usually done with Enlightenment (E)... but lately while running a DE 
then opening another pure (non-X) terminal to run E on, then switching 
back, E drops/crashes back to showing the command that started it, which 
mine is below.

#!/bin/sh
# Start second X session, using a xinitrc, in this case FreeBSD/E
#xinit /usr/local/etc/X11/xinit/xinitrc.enlightenment -- /usr/bin/X :1>/
dev/null 2>&1
# Start second X session, using a xinitrc, in this case GNU/E
xinit /etc/X11/xinit/xinitrc.enlightenment -- /usr/bin/X :1>/dev/null 2>&1
