Comment 112 for bug 549447

It looks like evdev comes up for my keyboard and handles power button events. I don't see anything for the touchscreen.

I think the problem is that the touchscreen is also giving input on /dev/input/mouse2 (as seen above) and /dev/input/mice. When I do

od /dev/input/mouse2

or

od /dev/input/mice

I see some data coming through when I touch the touchscreen. I think Xorg is listening to mouse2 or mice as a mouse, and misinterpreting the touchscreen input. I think the touchscreen can't run through the kernel mouse driver. The confusing part is, I don't see anything specific to mouse2 or mice in xorg.conf, or in Xorg.0.log, or in dmesg.

Could you post the relevant lines from your hal fdi file to get the egalax xorg driver to load (rather than synaptics?).

Thanks!
