Hmm, that's odd.  No clue why that would be.

Take a look at /opt/ltsp/i386/etc/inittab

only the first 3 screens are used by default.  If you want more, you
need to enable them, by setting the additional lines to 'respawn'.

We found the 8 extra screen sessions to be causing a ton of NFS traffic,
as they all wake up at the same time, and check the lts.conf file to
see if they are supposed to do anything.

It turns out to be very dependent on the video chipset.  Some of the
drivers and chipsets are very fussy when it comes to switching away from
them, and then immediately re-initializing a 2nd (or 3rd) screen.

What chipset do you have?
