Heya,
Built into my Lenovo A700 all-in-one is a touchscreen. lsusb says:
$ lsusb | grep -i touch
Bus 002 Device 006: ID 04e7:0022 Elo TouchSystems
The touchscreen "works", in that tapping it will create a click event,
though that click event is always in the top left of the screen.
Full output of lsusb -vvv attached.
Anybody with ideas as to what I'm missing, or whether that particular
device is supported?
Using kernel 2.6.38-rc2-git5 (from Fedora rawhide).
Cheers
