Request for help implementing Edubuntu and LTSP

[Jeremy Fluhmann]

Something else to throw out there is DRBL.  We're deploying a VDI 
solution from Virtual Bridges, which runs on a Linux infrastructure and 
can provide us Linux desktops, as well as Windows desktops.  We have 
numerous old machines similar to yours (anywhere from 6-9 years old) 
that we're setting up to run a basic Ubuntu desktop that will allow 
users to access our VDI portal and run their virtual desktop sessions.  
I've gone with DRBL instead of LTSP as we wanted applications to run 
locally on the machines (and I realize this can be setup as well with 
LTSP).  This has worked pretty well so far for us.  I still have some 
tweaking to do so that the machines auto login and run Firefox in full 
screen when they boot.

And since DRBL runs an image locally on the machine, you may find no 
issues with running a Windows virtual machine on it (other than the 
potential performance hit).

If looking at running both Windows and Linux desktops on these machines 
and want to centrally maintain a single image for each, I would 
recommend something like Virtual Bridges VERDE (licensing per concurrent 
session).

Our computer lab has about 20 wintel boxes that are about 8 years old. At present, the computers in the computer lab are used by students of all ages: nursery school to seniors in high school.

This setup is fine for most administrative duties but not necessarily for training (where students need to be able to break things and the teacher needs to be able to repair them). Also, in the computer lab we may have a wide variety of applications installed that either can't be installed on the Terminal Server or aren't appropriate there (since all users would then have access to them). In short, we're exploring ways to improve the efficiency of the computer lab and edubuntu + ltsp is a likely candidate.

I'm asking because for the youngest users it is a logistical nightmare to ask them to remember their own username and password and we'd like a single username and password we can use for all of them.
