Hi,
I have a new eGalax touchscreen (came with driver cd 5.1.0, if that helps).
I'm trying to use it from a Raspberry Pi, so I can't use the prebuilt drivers
on that CD. I've found the ARM-specific vendor drivers but I haven't installed
them yet as I remember this working without them on an older model of eGalax
touchscreen.
Even without those, it still seems to autodetect the touchscreen and it loads
the hid_multitouch driver, and within X the pointer moves according to touches
as expected. However it does not perform any "click" action when the screen is
touched. (I'm ok with it behaving like a single-touch mouse -- I just want it
to actually do something when touched.)
Is this a known issue, or something that can be fixed, or just a configuration
error? I've included some diagnostic output from various tools below in the
hope that it may be useful to identify and/or fix the issue; please let me know
if you need more information.
Note that at present I do not have anything specific in xorg.conf or
xorg.conf.d related to the touchscreen; this did not seem to be necessary with
the older hardware.
Regards,
Gavin Lambert

The above was the output from a single touch at approximately the centre of the
screen, in each test. The "Pen" device does not seem to be generating any
events on touch (but then I don't have a magic touch pen, just a finger or
passive stylus; I'm not sure if that makes a difference).
