Follow the below instructions to install Robert's fl_teachertool.  I think you'll be
very happy with it. Jim


1. Setup x11vnc on clients:

sudo cp /etc/apt/sources.list /opt/ltsp/i386/etc/apt/sources.list
sudo chroot /opt/ltsp/i386
apt-get update
apt-get install x11vnc
vi /etc/rc.local
x11vnc -display :6 -forever -shared -bg

# I didn't have to do the following since I had already moved K99rc.local to get 
cd /etc/rc2.d
mv K99rc.local S99rc.local

2. Download fl-tt source and install


apt-get install build-essential libfltk1.1 libfltk1.1-dev libxpm-dev vnc4server
xtightvncviewer zlib1g-dev libjpeg-dev xscreensaver

tar -zxvf fl_teachertool-041-ltsp5.tar.gz
cd Fl_TeacherTool-0.41
sudo make && make install

sudo chmod +x /etc/X11/xinit/xinitrc

sudo vim /etc/X11/app-defaults/XScreenSaver

*mode:                  random

replace the word "random" with "blank" on the line that matched the above (no quotes)

3. Download and install vnc-reflector


tar -zxvf vnc_reflector-1.2.4.tar.gz
cd vnc_reflector
sudo make
sudo cp vncreflector /usr/bin

4. Create vncuser on server and .vnc tree

sudo adduser vncuser
answer user options and set password

5. Logout and login with new vncuser, then run vnc4server 


Kill vnc4server

vim /home/vncuser/.vnc/xstartup

Uncomment the following 2 lines:
exec /etc/X11/xinit/xinitrc

Logout vncuser

6. Set vnc password and copy .vnc

sudo /usr/bin/vncpasswd
sudo cp -a /home/vncuser/.vnc /opt/ltsp/i386/root/

7. Run fl_teachertool and play away

sudo fl_teachertool
