[Bug 643212] Re: ntrig touchscreen no longer works

[Jayhawk]

I have found that the single-touch version (if the firmware is removed--
it also does not provide a firmware version) is no longer reporting
correctly.  I am pretty sure that the Vista firmware will report the
same issues.  The hid-ntrig.c source is only calling report_frame when
HID_DG_CONTACTCOUNT is received.  However, in the Vista firmware and
single-touch, it does not send that event.  It ends when HID_DG_HEIGHT
is sent.  Therefore the N-Trig Touchscreen (single-touch/Vista) version
will never report anything.  I have also found that the system will
crash occasionally when you touch the screen.

Attached is a patch that is currently working for me in single touch and
multitouch.  I hope this helps.

** Patch added: "Patches to allow single-touch events to be reported."
