Sorry for last comments, actually the remaining bug is probably in
xserver-xorg-core
(as reported in bug #799202 , pressure in Krita works fine using
xserver-xorg-core 2:1.10.1-1ubuntu1 , but after updating it
to 2:1.10.1-1ubuntu1.1 it doesn't work right anymore…)
So this bug here in qt4-x11 is
Hey! I've just tried Oneiric Alpha2, freshly installed/updated
Now in Krita there is NO STROKE AT ALL (not just no pressure, or strange
diagonal lines... no stroke at all)
Weird thing is that it works in Pencil (but Pencil only use pressure
sensors from wacom, while Krita use all features
Additional infos:
The report above was with a Graphire4.
So in Oneiric, with a Graphire4, it's impossible to paint in Krita.
With Intuos3, stylus can draw strokes with pressure but still produce weird
parasite diagonal strokes that prevent from using it.

Please test and give feedback here.
Removed all custom repos, enabled natty-proposed, did full upgrade and
restarted. I've lost track of what is what, but at the moment in Krita:
1) pressure sensitivity works
2) Intuos button presses do not jump the cursor
3) problem with diagonal lines
Being fixed. No release note needed.
