[Linuxwacom-discuss] Lenovo Thinkpad Yoga pressure problems

[Carl O. <car...@gm...>]

I've just got myself a Lenovo Thinkpad Yoga tablet PC and I'm having
issues with pressure sensitivity.

What the pressure output looks like with smooth in-and-out strokes:

These newer tablet PCs thend to have an expanded pressure range than
the older ones, 1024 vs 256 so could the value be overflowing perhaps?

I've tried with drivers from the Linux Mint repos, build from latest
source package and build from git, all with the same result.

Stylus tracking and buttons both worked fine from the start. Pressure
works fine in Windows.

I believe the digitiser is of the "Feel It" type.

Output of "xsetwacom --list":
Wacom ISDv4 EC Pen stylus       id: 11 type: STYLUS
Wacom ISDv4 EC Pen eraser       id: 15 type: ERASER

Any ideas what's causing this?
