Title: usbtouchscreen xvesa
Post by: smultita on April 05, 2011, 07:24:41 AM

Is it possible to use an usbtouchscreen under xvesa or
some workaround possible ( XTestFakeMotionEvent, /dev/input/eventx, gpm repeater mode)?

If I start a clean tinycore and connect my USB touchscreen it does work (exept for calibration)
and /dev/input/event6 is created.

Is this some generic driver in the kernel?
Then were is usbtouchscreen.ko for (which if I thought creates this input event)?

I installed and run evtest and get the following output
evtest /dev/input/event6

</snip>

To get it working with calibration would the folowing work:
I write a program which reads the /dev/input/event6 and translates it (calibrate)
- into XTestFakeMotionEvent() or 
- into a new created /dev/input/event7
or does this give a conflict (multiple pointer movement)?

I've written a program reading /dev/input/eventx and translate into XTestFakeMotion and Button evens.
This enables touch in XVesa (and Xorg) and should work for most USB-HID Touch devices.
I will submit a tcz soon

Good work - but why you fixed it on DISPLAY=:0?

I have a script which builds an extension for ELO touchscreens using the source from their website, but it requires Xorg. I added the calibration program to .xsession so it would start every time since I wasn't saving calibration data. If you want it let me know and I will get it from my work computer this weekend.
