GIMP 2.7.4 nightly builds now compile on 64bit Ubuntu 11.10, while
previously version 2.7.3 would not (see posts #40 and #44).
The following commands will install this unstable work in progress:
Open command prompt run the following commands
sudo add-apt-repository ppa:matthaeus123/mrw-gimp-svn
Update the source list
sudo apt-get update
Upgrade gimp using the following command
sudo apt-get dist-upgrade
While this version does not fix the problem with data loss while drawing very
fast (line breaks) there appears to be less of a drop-out problem and the line
thins right before the line breaks. Then there is a recovery with a thin line
and then it goes back to a normal pressure drawing line again. This is somewhat
different then what I described in Post #44 and #45 regarding GIMP 2.7.3. There
you would be drawing a line and it would just break and then reappear as you
did quick scribbling of large circles.
I noted that today there was also an update of UPSTART version 1.3-0ubuntu11
which is an "event-based init daemon" a 288kB download, which might be
relevant. UPSTART is a replacement for the /sbin/init daemon which handles
starting of tasks and services during boot, stopping them during shutdown and
supervising them while the system is running. It appears the frequency of
streaking lines to the edge of the windows in GIMP 2.6 may have also lessened
somewhat but is still present. In either case 2.6.11 or 2.7.4 there seems to be
somewhat of an improvement over two weeks ago. Has anyone else noticed this?
To reproduce this bug set GIMP to draw with Pencil in NORMAL mode, set
brush to ROUND FUZZY, point size to 6, set to BASIC DYNAMICS, leave all
other settings in 0.00 or their defaults in the left-hand window. Set
your tablet to SCREEN configuration. Then try and draw big sweeping
circles quickly in a window set for say 800x600 at 96dpi.
There is no problem at all... as long as you don't draw real fast in
ver. 2.7.4... which is kind of a show-stopper for most. Note that I am
using the Genius Mousepad 8x6 tablets because my daughter and I am just
getting into this and I didn't want to shoot for WACOMs. So WACOM users
should try this and see how it works in your environment and report back
here because this is the most substantial thread on this bug problem.

Title:
Wacom Bamboo One tablet random coordinate malfunctions
Status in The GNU Image Manipulation Program (GIMP):
Unknown
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)
