I wrote a touchscreen calibration routine for exactly the same driver,
but unfortunatly I did it bass-ackwards so I dont know the correct way
of doing this (i.e. unloading the elographics_drv.o and modifying the
X config file), but its nice to hear that someone is going to do it right ;-D
If you write it in Qt, you'll drag in IMO alot of dependancies for a simple
calibration tool, I would sugest doing it in raw xlib (but thats just me...)
If its any help, you might want to look at this fix:
I'll be sending that patch to xorg bugzilla as soon as I get the
chance to look at the xorg code.
If its any help, when I wrote my calibration I used a named pipe
to transmit raw values to the calibration app from the server,
this was tricky because the libc wrapper did not support
non-blocking io, its an easy fix though, just look at
Ofcource this is xfree86.org specific, I have no idea right now if
the xorg tree differs in respect with input modules and their protocol.
