Experiencing same horizontal and vertical line spikes utilizing two
Genius Mousepad 8x6 tablets on both 386 and AMD-64 Ubuntu 11.10 machines
utilizing latest NVIDIA 280 drivers and GIMP Editor. Confirm that
disabling the Extended Input Devices stops the problem. However, without
Extended Input Devices enabled the tablets will not have pressure
sensitivity capabilities. This problem did not exist in UBUNTU 11.04.

Tested and Confirmed this problem pertaining GIMP with the following UBUNTU 11.10 shells:
GNOME, GNOME Classic, UNITY, UNITY 2D, Lubuntu, LXDE Session, Xubuntu, Xfce Session

Additionally Martin Owens PPA for Wizardpen Drivers does not include the latest version for Oneiric Ocelot 11.10

deb http://ppa.launchpad.net/doctormo/xorg-wizardpen/ubuntu YOUR_UBUNTU_VERSION_HERE main 
Only Natty version and earlier available.

Inkscape drawing works but pressure sensitivity does not.  But I believe
this was also the case in version 11.04.

SynfigStudio also works but you must manually install as the Ubuntu
Software Center will not install even though it is listed. There appears
to be no setup for tablets so again..., no pressure sensitivity
capabilities.

Regarding Blender..., Drawing OK, all pen buttons work. Pressure
sensitivity is supposed to be active in SCULPT MODE but I couldn't get
it to work. But this could be due to my ignorance of the proper use of
this function.

Considering that the BIG BUCK BUNNY project lists the use of SYNFIG
STUDIO, BLENDER, GIMP and INKSCAPE as tools , this bug presents itself
as a serious problem meriting top priority regarding a fix.

Title:
  Wacom Bamboo One tablet random coordinate malfunctions

Status in “gimp” package in Ubuntu:
  Confirmed

Bug description:
  The tablet in overall seems to work correctly, with all pressure-
  features working. But quite frequently, while drawing, GIMP seems to
  wrongly read the coordinates of the stylus (as zeros, or negative
  values?), resulting in frequent, random 'line-peaks' in the direction
  of the left and upper image edges. With this bug it is hard to even
  use the tablet, since these problems are very frequent (see the
  exemplary image attached).

  The tablet works with no problems in MyPaint. The bug is reproducible
  in both Unity-2d and Unity-3d.

  I also notice the CPU usage increasing dramatically during drawing
  with any brush.

  Steps to reproduce:
  1. Connect the Wacom Bamboo One tablet
  2. Open GIMP
  3. Start drawing longer strokes with any brush

  Expected result:
  The brush stroke as intended by moving the stylus

  Actual result:
  The brush stroke as intended with frequent, random line-strokes towards image edges

  System: Ubuntu 11.10 oneiric (development branch)
  GIMP version: 2.6.11 (package version: 2.6.11-2ubuntu3)
