The biggest difference between the way Ubuntu has implented LTSP and how
we've been doing it, is they don't use Xdmcp.
They use a local display manager that they've named 'LDM' == Ltsp Display
Manager. It's just a gui wrapper around ssh. You enter your username and
password, and LDM passes them on to ssh, which then invokes the xsession
script on the server. the Xsession script then launches gnome. At this
point, the DISPLAY env variable is something like 'localhost:10.0'. So,
Robert's technique of looking for 'ws001:0.0' breaks when using Ubuntu's
I'm sure there are other things in Ubuntu-ltsp that can cause problems for
Teachertool, but that's the big one.
