How to blacklist a module for the LTSP clients
This little instruction (from a newbie to other
newbies) on blacklisting a module for the LTSP client boot process
applies specifically to Lubuntu and i386 clients. For other
flavors of Ubuntu, you would substitute the equivalents for
lxterminal, sudo and leafpad. If you were using 64-bit or Power
PC clients, you would also have to substitute whatever is
appropriate for i386.
This also assumes that you know the name of the module you want to blacklist. This post does not cover how to determine the name of a module to be blacklisted.
Run Lxterminal (from Accessories in the program menu). To open the file containing the blacklist entries, enter at the prompt:
sudo leafpad /opt/ltsp/i386/etc/modprobe.d/blacklist.conf
Add the following to the end of the file, save, and exit leafpad:
blacklist module-name
(Replace module-name with the name of the module you are blacklisting.)
Then in Lxterminal once again, enter at the prompt:
sudo ltsp-update-image
Though note that ltsp-update-image must produce the image for the correct architecture on the clients. It defaults to using the same architecture as the host. But if the host were, for instance, 64-bit and the clients 32-bit (i386), then the architecture of the clients must be specified with a command option. In this case:
sudo ltsp-update-image --arch i386
Updating the image takes some time. When it is finished it will return you to the Lxterminal prompt. Enter the exit command to close Lxterminal.
