Public bug reported:
I recently changed from Ubuntu 14.04 to 16.04. I re-installed from
scratch as I was moving from 32bit to 64bit.
My lenovo x201 tablet's touch screen and stylus did work fine with 32bit
14.04.
Now the touch screen is not even recognised.
It does not show up in System Settings > Wacom Tablet
Running:
xsetwacom --list devices
returns nothing.
sudo lshw | grep wacom
returns nothing.
xinput returns:
⎡ Virtual core pointer id=2[master pointer (3)]
⎜ ↳ Virtual core XTEST pointerid=4[slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPadid=11 [slave pointer (2)]
⎜ ↳ TPPS/2 IBM TrackPoint id=13 [slave pointer (2)]
⎣ Virtual core keyboard id=3[master keyboard (2)]

...but no mention of the wacom touchscreen.
The following file is present on my system:
/lib/udev/rules.d/69-wacom.rules
it contains the following:
ACTION!="add|change", GOTO="wacom_end"
# Match all serial wacom tablets with a serial ID starting with WACf
# Notes: We assign NAME though we shouldn't, but currently the server requires
it
#We assign the lot to subsystem pnp too because server reads NAME from
#the parent device. Once all that's fixed, as simple SUBSYSTEM="tty"
#will do and the ENV{NAME} can be removed.
