This sounds interesting - is this a big job? If this was implemented in the X server, I imagine that it may be of use to others who wish to use similar hardware. I might be interested in giving this a try, but I would need some pointers as to where to start, as I've never worked on any X server type code before. I've done some tinkering with drivers, but in a very limited fashion... > The tablet I've seen uses the silicon motion chipset which does the > rotation during video output, making things much easier. > > Keith Packard XFree86 Core Team HP Cambridge Research Lab > Thanks Mark _______________________________________________ Xpert mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xpert
