Does anyone know the format of the pointercal file?
The contents are like this
21596 0 173612 0 14745 978165 65536
If I manualy input this file I can get my 5500 to start by bypassing the calibration screen.

I have tried two different sets of numbers as above and both are far enough off that it makes the touch screen unusable. If I knew what these numbers meant I might be able to adjust them so by digitizer works properly.

Ok, since I'm looking for the same information, here is an indirect refence: onThe QWSCalibratedMouseHandler -Qt 4.3- Reference Page there's a couple of equations that use the seven numbers (a, b, c, d, e, f and s) in /etc/pointercal to translate from device coordinates (Xd, Yd) to screen coordinates (Xs, Ys). In case that page was to disappear, here are the equations:

s*Xs = a*Xd + b*Yd + c
s*Ys = d*Xd + e*Yd + f

I'll have to play a bit with it on my N800, and see what happens.
