This guide is based on Ubuntu 12.04
There are two parts to this guide. One part will have commands to install a 32-bit client, the other part will have commands to install a 64-bit client.
When you see this
root@ltsp-server:~#
It means the commands should be executed on the LTSP server.
When you see this
root@ltsp-server-chroot:/#
It means the commands should be executed on the LTSP server, but after you have run the chroot command ltsp-chroot. Chroot is type of isolated environment.

Assumptions
- Your mythtv server has an IP address of 192.168.1.100
- Your mythtv frontend is diskless, it will use a dhcp client address of 192.168.1.150
- You will create a new user called mythltsp
- Your mythtv server resolves DNS queries
- Your default router IP is 192.168.1.1
- Your mythtv server is not already serving DHCP
- You mythtv frontend has a mac address of 87:01:2a:ab:08:56
Install the LTSP Server Software
root@ltsp-server:~# apt-get install ltsp-server-standalone
Configure DHCP
Installing the ltsp server software will create a dhcpd config file /etc/ltsp/dhcpd.conf
You already have dhcpd running, this new file will override it.
Dhcpd is used to provide the client frontend with an IP address.

Your server must have an interface serving this range. subnet 192.168.1.0 netmask 255.255.255.0 { range 192.168.1.150 192.168.1.200; option domain-name "example.com"; option domain-name-servers 192.168.1.100; option broadcast-address 192.168.1.255; option routers 192.168.1.1; # next-server 192.168.0.1; # get-lease-hostnames true; option subnet-mask 255.255.255.0; option root-path "/opt/ltsp/i386"; if substring( option vendor-class-identifier, 0, 9 ) = "PXEClient" { filename "/ltsp/i386/pxelinux.0"; } else { filename "/ltsp/i386/nbi.img"; } host mythfront { # tftp client hardware address, mac address of your LTSP client hardware ethernet 87:01:2a:ab:08:56; # Dedicated IP address for your LTSP client fixed-address 192.168.1.150; # Uncomment the line below if your client is 32-bit # filename "/ltsp/i386/pxelinux.0"; # Uncomment the line below if your client is 64-bit filename "/ltsp/amd64/pxelinux.0"; } }
Restart DHCP
root@ltsp-server:~# service isc-dhcpd-server restart
Build client settings

# ubuntu-desktop and edubuntu-desktop are tested. # Ubuntu 12.04 LTS working perfectly with Unity and Unity 2D. FAT_CLIENT_DESKTOPS="ubuntu-desktop" # This uses the server apt cache to speed up downloading. # This locks the servers dpkg, so you can't use apt on # the server while building the chroot. MOUNT_PACKAGE_DIR="/var/cache/apt/archives/"

#configuration file for ltsp-update-image # Do not compress the client image. Comment out the line below to enable again. NO_COMP="-noF -noD -noI -no-exports"
Set up Thin Client user
This account is created on your LTSP server. The LTSP client will use it to login.
root@ltsp-server:~# useradd -m mythltsp -G sudo mythtv root@ltsp-server:~# passwd mythltsp root@ltsp-server:~# su - mythltsp $ mkdir .mythtv $ cd .mythtv $ ln -s /etc/mythtv/mysql.txt mysql.txt $ ln -s /etc/mythtv/config.xml config.xml $ exit
Create the initial client image
root@ltsp-server:~# ltsp-build-client
Start of 32 bit LTSP Client Instructions
Boot the LTSP client
Try to login, if you get an error that gnome failed to load
root@ltsp-server:~# ltsp-chroot root@ltsp-server-chroot:/# apt-get install gnome root@ltsp-server-chroot:/# exit
Create a new image
root@ltsp-server:~# ltsp-update-image --arch=i386
Boot the LTSP client
Client boots and can now login. MythTV is not installed
Update repositories the client can use
root@ltsp-server:~# cp /etc/apt/sources.list /opt/ltsp/i386/etc/apt/sources.list root@ltsp-server:~# cp /etc/apt/sources.list.d/* /opt/ltsp/i386/etc/apt/sources.list.d/
Install MythTV Frontend
root@ltsp-server:~# ltsp-chroot root@ltsp-server-chroot:/# apt-get update root@ltsp-server-chroot:/# apt-get install mythtv-frontend root@ltsp-server-chroot:/# exit
Create a new image
root@ltsp-server:~# ltsp-update-image --arch=i386
Boot the LTSP client
This time mythtv frontend will be available
Now configure it
root@ltsp-server:~# ltsp-chroot
Update the settings for your backend, DBHostName and DBPassword will have to be changed.
root@ltsp-server-chroot:/# vi /etc/mythtv/mysql.txt
This assumes you have a link from your local user home dir to the /etc/mythtv config dir
eg.
/home/mythltsp/.mythtv/mysql.txt -> /etc/mythtv/mysql.txt
root@ltsp-server-chroot:/# exit
Create a new image
root@ltsp-server:~# ltsp-update-image --arch=i386
Boot the LTSP client
This time, mythtv frontend should connect to the backend.
Enable auto login
root@ltsp-server:~# vi /var/lib/tftpboot/ltsp/i386/lts.conf

[Default] # Auto Login LDM_AUTOLOGIN = True LOCAL_APPS = True LDM_SESSION = "lightdm-gtk-greeter" [192.168.92.120] LDM_USERNAME = mythltsp LDM_PASSWORD = mythltsp
Boot the LTSP client
This time, mythtv frontend should automatically login and connect to the backend.
End of 32 bit LTSP Client Intructions
Start of 64 bit LTSP Client Instructions
Create the initial client image
root@ltsp-server:~# ltsp-build-client --arch amd64
Boot the LTSP client
Try to login, if you get an error that gnome failed to load
root@ltsp-server:~# ltsp-chroot root@ltsp-server-chroot:/# apt-get install gnome root@ltsp-server-chroot:/# exit

Install MythTV Frontend
root@ltsp-server:~# ltsp-chroot root@ltsp-server-chroot:/# apt-get update root@ltsp-server-chroot:/# apt-get install mythtv-frontend root@ltsp-server-chroot:/# exit
Create a new image
root@ltsp-server:~# ltsp-update-image --arch amd64
Boot the LTSP client
This time mythtv frontend will be available
Now configure it
root@ltsp-server:~# ltsp-chroot
Update the settings for your backend, DBHostName and DBPassword will have to be changed.
root@ltsp-server-chroot:/# vi /etc/mythtv/mysql.txt
This assumes you have a link from your local user home dir to the /etc/mythtv config dir
eg.
/home/mythltsp/.mythtv/mysql.txt -> /etc/mythtv/mysql.txt
root@ltsp-server-chroot:/# exit
Create a new image
root@ltsp-server:~# ltsp-update-image --arch amd64
Boot the LTSP client
This time, mythtv frontend should connect to the backend.
Enable auto login
root@ltsp-server:~# vi /var/lib/tftpboot/ltsp/amd64/lts.conf

[Default] # Auto Login LDM_AUTOLOGIN = True LOCAL_APPS = True LDM_SESSION = "lightdm-gtk-greeter" [192.168.92.120] LDM_USERNAME = mythltsp LDM_PASSWORD = mythltsp
Boot the LTSP client
This time, mythtv frontend should automatically login and connect to the backend.
Optional: Install NVIDIA drivers
Note: if your main LTSP server is 64 bit and your LTSP client is also 64 bit this step will work. If your LTSP client is 32 bit you will need to work out how to install the 32 bit version of the nvidia driver.
root@ltsp-server:~# ltsp-chroot
You must mount proc or you will get errors when you install the nvidia drivers
root@ltsp-server-chroot:/# mount -t proc proc /proc root@ltsp-server-chroot:/# apt-get install linux-headers-`uname -r` root@ltsp-server-chroot:/# apt-get install nvidia-current nvidia-settings root@ltsp-server-chroot:/# nvidia-xconfig
Boot the LTSP client
This time, the LTSP client should be using the NVIDIA drivers. If you can't see the edges of your screen, you have a condition called "overscan".
Edit /etc/X11/Sxorg.conf
Add this to the bottom of the "Screen" section
Option "metamodes" "DFP-0: nvidia-auto-select +0+0,DFP-1: 1920x1080 { ViewPortIn=1920x1080, ViewPortOut=1820x1020+45+30 }"
root@ltsp-server-chroot:/# exit
Create a new image
root@ltsp-server:~# ltsp-update-image --arch amd64
Boot the LTSP client
You should now see the full menus on around the edges of your screen.
End of 64 bit LTSP Client Instructions
Troubleshooting
Make MythTV use the full screen when it launches
There is a known issue with mythtv launching and not using the full screen. A Compiz bug that was reported here:
http://code.mythtv.org/trac/ticket/9589
Run these commands to implement a fix
root@ltsp-server-chroot:/# apt-get install compizconfig-settings-manager root@ltsp-server-chroot:/# exit
Create a new image
root@ltsp-server:~# ltsp-update-image --arch=i386
or
root@ltsp-server:~# ltsp-update-image --arch amd64
Boot the LTSP client
After the LTSP client has booted, login using the mythltsp user
Run the ccsm tool.
- Under CompizConfig Settings Manager, go to "Utility"
- Go to "Work arounds"
- Check "Legacy Full Screen" support.
Create a new image
root@ltsp-server:~# ltsp-update-image
Boot the LTSP client
Mythtv frontend should now use the full screen.
Maintenance Updates
Kernel Updates
If you apply a kernel update to your LTSP server you need to run this command to update your client
root@ltsp-server:~# ltsp-update-kernels
