Pardon my jumping in, but is turtle available from the interactive
shell? The turtle module should be in /usr/lib/Python2.6/lib-tk on an
Ubuntu 10.4 installation. If it is, then it should work fine from your
scripts. Is it available for you when you log onto the machine directly?

   Well, I set up 25 PCs in my classroom on a gigabit LAN.  Each PC is
   running Ubuntu Desktop 10.04 - so, yes they have gnome and yes they
   have a GUI browser (Firefox).

   I took one of these PCs and called it the "server/teacher station."
     On this PC I added vsftp to share files with my students and
   openssh so they can login to my PC as a server to save their work.

   I call my PC the "teacher station" because I use it with a PC
   Projector and a Slate (bluetooth remote mouse) mimicking a
   SmartBoard setup to demo code and give notes and even show some
   educational YouTube!  I recently added python and IDLE to this server:

   apt-get install python
   apt-get install idle

   We tried IDLE but prefer python scripts.  So, I have my students
   login to the server via ssh from their "student stations" and write
   python scripts like hello.py which they chmod to make executable

   chmod 755 hello.py

   which works fine if the first line in the script is

   #!/usr/bin/python

   I tried to import turtle in a script using this environment but
   turtle was not found.

   You say VPython works well with IDLE?  I was hoping to add VPython,
   GASP or turtle graphics to my scripts.

   What do you think?

>From what I've read so far, the students are SSHing into a sever, and writing their scripts from there (nano, vi, etc?). AFAIK, SSH is usually just shell, which means no GUI from the host, and they can't use turtle because it is a GUI app, using Tkinter IIRC.

Right, the turtle and Tkinter are GUI apps, but the OP said they connect with the -Y parameter for X11 forwarding, so it should open an X11 window on their machines - this is standard behavior for ssh. And the OP said turtle was not found, not that a screen couldn't be opened.

Cheers,
Vern
