[Bug 799202] Re: wacom stylus jumps with latest xserver-xorg-core

 

Hmm, looks like we are progressing in what the problem is.

As suggested by Jussi, I tried the tablet sample app from qt4-demos, and
I can confirm that pressure works fine.

However in that demo app, when I try to use the "tilt" value from the
tablet to set line width (in the Tablet menu > Line width > Tilt), I get
some strange results: a rather constant fine line with sometimes a
random huge rect appearing. Trying to set the color saturation from the
"Tilt" value doesn't work either. The behavior is the same on my
Touchscreen and on my Intuos 3 usb.

I tested with the "unpatched" xserver (without the 503 patch), and with
this version, setting line width from the tilt value works fine on my
intuos 3, and the line width stays fine on my touchscreen that maybe
doesn't provide a tilt value, but I never get those random huge rects.

So it looks like the problem introduced (or revealed) by patch 503 may
be with the tilt value, not the pressure...
