This page is dedicated to installing the 'thin-client-manager-gnome' package on LTSP servers, and installing the 'x11vnc' package in the thin-client chroot environment to allow viewing, controlling, broadcasting, messaging, etc. on thin-clients.
This is the quick HowTo to get x11vnc running on thin clients so you can connect to them using a vncviewer or the thin client manager app. note that this doc doesnt take security into account, if you want a safe solution enable a password for x11vnc
First, install the management application on the server:
sudo apt-get install thin-client-manager-gnome
Before installing in the ltsp environment, make sure that apt-get sources in ltsp are consistent with the base install:
sudo cp /etc/apt/sources.list /opt/ltsp/i386/etc/apt/sources.list
Now, chroot into the ltsp client environment on the server.
sudo chroot /opt/ltsp/i386
Update the repositories that the ltsp environment uses for apt-get:
apt-get update
Install the x11vnc package (it's in the universe repository, possibly you must add it in /etc/apt/sources.list; in this case don't forget to apt-get update):
apt-get install x11vnc
Now edit the rc.local file to add x11vnc to the system startup (note: make sure this is all being done in the chroot environment and not the root of the server)
vim /etc/rc.local
Add the following line before the exit 0 statement in this file and save it:
x11vnc -display :6 -forever -loop -shared &
Now lets make sure rc.local gets actually executed:
cd /etc/rc2.d
mv K99rc.local S99rc.local
Exit the chroot environment:
exit
Ubuntu/Edubuntu 7.10 and onwards - Make sure that the ltsp image gets updated:
sudo ltsp-update-image
If you are using an i386 image on an AMD64 build the command is:
sudo ltsp-update-image --arch i386
Reboot your thin clients and you should be able to connect to them via vnc now.
