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.

(interrupt to exit) 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). -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
