[Linuxwacom-devel] N-Trig touchscreen

[Rafi R. <ra...@ug...>]

I have a laptop with an N-Trig touch screen.  After a few lines of 
tweaking the digitizer works fairly well with 8.0-3 driver.

Would support for this non-wacom device be welcome?

vendor: 0x1b96
tablet id: 0x0001

With the 8.0-3 driver the stylus worked flawlessly.

However to get the touch part working I had to move the event->code == 
BTN_TOOL_BRUSH to the cursor device and change the axis 2 and 3 to 0 and 
1 respectively (the touch was showing up as wheel and a tilt action).

Though a bit hackish, that solution seems to work.  But for some reason 
the cursor gets sent to the lower right of the screen when I lift my finger.



With the 8.1-1 driver once I put in the axis swap again, the pointer 
moves around just fine.  But when I touch the pen to the screen the 
events get passed to the touch device.  Also since the device does not 
have a wacom vendor id, the default capacity doesn't get set thus, the 
touch clicks are lost.  Also once that's fixed the cursor still jumps to 
the lower right when I lift my finger.

On a side note, though the tip button is captured as a touch, if the 
eraser button is held during the press, the event still goes to the 
eraser device.



Eventually, I'd also like to get the multi-touch feature working.  I'd 
be happy to help write the code, once I understand the driver a bit better.
