Alejandro, I've used both serial and parallel LCD panels. I've only used the serial one on Linux which just involved sending bytes to a com port. Most LCD panels come with a 'parallel' interface and I've driven one from a DOS printer port before. The panels are kind of simple - you present 8 (or 4) bits of data and then a 'strobe' to clock the data into the panel. The panels usually come with an instruction set. I don't know how to drive a parallel port from linux though (sorry). Andy.
