Tablet works partly, ie pressure, but not tilt.
I had first build and installed linuxwacom 0.8.8-11 and xf86-wacom 0.10.99.2, but with no success. Then I installed xserver-input-wacom from irie's ppa, but with no more success.
xorg.log shows "wacom class" is applied (as in xorg.conf snippet) and tilt=enabled.
/dev/input/ has wacom, event* and tablet-intuos4-8x13, thanks to udev I think.
Xorg is 1.9 I think.
I'm using xidump and mypaint to check stylus tilt.
Any help will be greatly appreciated.
kernel driver seems to be working, as reports evtest (http://pastebin.com/5mX9Dhtc).
I've upgraded ubuntu to 11.04, so xf86-wacom driver is now irie's version 0.11.0+git20110419-0irie1~natty1 and kernel driver is (I supposed) build by irie's wacom-dkms 0.10.11-0irie1.
