I have a Sitronix ST9RM01 touchscreen that I'm trying to get working with Ubuntu 12.04.

The touchscreen is apparently recognized by Linux and X - the hid_multitouch module is loaded, and lsinput and xinput both list the touchscreen as an input device - but touching the screen does absolutely nothing, and xinput test shows no events.

The same touchscreen works just fine in Windows.

How can I troubleshoot from here? Any suggestions?

From talking with one of the hid-multitouch developers, the following will commands will work around this problem in Ubuntu 12.10:

sudo su
echo 16 > /sys/module/hid_multitouch/drivers/hid\:hid-multitouch/0003\:1403\:5001.*/quirks

A future kernel update will fix things so that this will no longer be necessary.

Try this

Then type:

sudo apt-get install xserver-xorg-input-multitouch

sudo gedit /usr/share/X11/xorg.conf.d/50-multitouch.conf 

then replace driver multitouch by driver hid-multitouch

Reboot and it should work.
