Bug Description
The ThinkPad X220 Tablet multi-touch does not work out-of-the-box with utouch; instead the input is (sometimes) handled directly by applications. According to Chase, ideally (just) the "ISDv4 E6 Finger touch" should be diverted to utouch, with the Pen input remaining connected as normal. Enumeration:
$ sudo dmidecode -s system-version
