Well I boot up a client and log into ctrl+alt+f1 and log in.  I installed htop into the
client chroot for easier troubleshooting.  I run htop and find x11vnc running owned by
root.  I then switch back to ctrl+alt+f1 and log in.  I check screen 1 and htop still
shows x11vnc running.  I switch back to screen7 and logout, then back to screen1, now
x11vnc process is gone and I cannot use vnc modules of fl_teachertool.  

I thought that maybe xterminator was the problem, so I removed it (along with the
/etc/X11/Xsession/10-xterminator gotcha).  I rebooted the client and am still seeing the
same issues, so xterminator can be crossed off the list.  So for some reason logging out
is killing the process.

More later, have to pick up my kids :-)
