I have been using LTSP for a while to turn old PCs into X terminals. LTSP works well for a desktop PC that can use PXE or Etherboot. LTSP does not work as cleanly on old laptops with PCMCIA network cards. In these cases, the kernel has to be installed on the laptop hard disk, but the rest of the LTSP installation runs from the server. When upgrading LTSP, the kernel on the hard disk gets out of sync with the modules on the server, and the laptops stop working as terminals.

I've been looking for a simpler setup for a laptop X terminal, and I've found ThinStation.

With LTSP, all applications run on the server. This is great for the low maintenance involved: install an application program once, and it is available immediately on all terminals.

However, some times you may want to discriminate between different terminals. For example, you may want to restrict web browsing at one terminal or another.

I have an old laptop being used as an LTSP X Terminal. I have found that the X server software for this laptop is buggy. Somehow Mozilla exposes a bug that locks up the terminal.

LTSP is the Linux Terminal Server Project.

It is a software package which turns old cheap low-power PCs into X Terminals whose desktop software runs on a central Linux server.
