GENIUS MOUSEPAD 8x6 TABLET FIXED

Confirmed that "sudo add-apt-repository ppa:aapo-
rantalainen/gimp26-noghostline" patch worked with UBUNTU 11.10 and
Genius Mousepad 8x6.

Procedure:

1.  Remove GIMP with Software Center
2.  Open Terminal and type the following:

sudo add-apt-repository ppa:aapo-rantalainen/gimp26-noghostline
sudo apt-get update
sudo apt-get install gimp

3.  After installation, add back any other related extensions through Software Center.
4.  Load GIMP.
5.  Configure Input Extensions under Preferences.
6.  Disable all pointing devices except for the first tablet listing which you set to SCREEN. (This activates the Pen. The second tablet listing is for the Genius Mouse which you don't need.)
7.  SAVE and CLOSE the Input Dialog Box.

Your done. It works. I'm happy again. Thank you Aapo Rantalainen for
your help solving a problem that has plagued so many of us. Also thanks
to Alexia Death for the initial lead.

Title:
  Wacom Bamboo One tablet random coordinate malfunctions

Status in The GNU Image Manipulation Program (GIMP):
  New
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)
