A good thing for you is that the Linux driver is one for most of the Epson chips (download the file, you will see this sd1d1xxxfb.c (or something like it) file, it depends on different includes for different chips, but other than that it is always the same driver. >Has it got X-Window driver[s] or only frame-buffer support?

On the other hand, unlsee you want a lot of applications on the desk, ditching X would help you in maximizing CPU usage as you request below. Qt-E by Trolltech (Disclaimer: I am a fanatical Qt user) supports Fb graphics, so if you do not need anything besides a browser (Opera can also use Qt-E, and Konqueror can also link agains it, although I would not recommend that one yet), you can well do without X. >FL> I believe the card is enough for browser operation, yes.

But removing X from the equation will certinly gain you some % of CPU availability, which you will need for the soft mpeg decoder. You also want to test that the buffer setup of the whole thing is designed correctly for the kind of response and thruput you will need... I have seen reports on the mailing list of people having trouble b/c of some crippleware used in bus implementations. -Federico -- _________________________________________ -- "'Problem' is a bleak word for challenge" - Richard Fish Muad'Dib of Caladan (Federico L.
