[Linuxwacom-devel] Lenovo X201 Tablet troubles

[AndrewP <ins...@gm...>]

Greetings everybody,
     I got Lenovo X201 Tablet which is equipped with Wacom serial tablet
device (with no Touch support).
     I encounter 2 troubles, when trying to use my tablet:

1. Pen is overly sensitive, very quickly pressure goes to the highest value,
even with slight press on pen.
2. I got false clicks (especially when pen is tilted)

With whot's help I've run the isdv4-debugger and here are several cases:

http://dpaste.org/zZJI/ - here I hovered stylus around WITHOUT touching
screen of my tablet pc. Here we can see false clicks. I also noticed
reported presure level is correlated with proximity distance (seems linear
at some point), even without any touch
.
http://dpaste.org/YkkI/ - usual use, with several strokes and hovering

http://dpaste.org/PLwC/ - hovering with just touching screen surface,
without applying any force to it, next to usual strokes.

also I compared debugger output and xinput --test output, when xinput
reports pressure level 2048 debugger shows somewhere around 100 (more or
less)

I hope somebody could help me with that. If I can provide more useful
information, please tell me what to do.
