[Gimp-user] GIMP and Tablets ...endless story, I expect.

[Jan Kandziora <jjj gmx de>]

Hello,

I have an Aiptek6000U tablet, for which I finally got the kernel driver
working. "evtest" reports what seems to be correct.

X11 is configured as follows:


Section "InputClass"
  Identifier "pen"
  MatchProduct "Aiptek|AIPTEK|aiptek"
  MatchDevicePath "/dev/input/event*"
  Driver "aiptek"
  Option "USB" "on"
  Option "Type" "stylus"
  Option "Mode" "absolute"
  Option "zMin" "0"
  Option "zMax" "511"
EndSection


However, I had a hard time to get GIMP to do what I want. I configured
the tablet through Edit->Preferences->Input Devices->Configure Extended
Input devices->Device: Aiptek, Mode: Screen, Axes: X-1, Y-2, Pressure-3.
Xtilt-none, Ytilt-none. Moving the Stylus cursor and pressure works. Now
to the big BUT:

To have the stylus drawing I have to press the lower button on it. This
works *sometimes*. And there is no way to stop drawing again. Plus,
switching tools is not possible, GIMP doesn't react to the keyboard
while the stylus is in use.

What I'm doing wrong? How is it supposed to work?

Kind regards
