 Select wacom Device

I see three diffrent devices: core pointer, stylus and eraser. Gimp also 
recognizes which tool is genrating the actual movement.

 Select Mode (screen maps the tablet rectangle to the entire screen;
 window maps it to the Gimp canvas window)

Here I see something odd - and maybe this helps solving the problem.
If I disable a device, the device is removed from the list of available 
devices but it still works - but only as a pointer with pressure=max or 
pressure=off, i.e. like a mouse.
And the mode Window and Screen does not matter where I can use the device.

Maybe it helps when I provide you with two snipplets from my XF86Config (it 
is for XFree 4.1):

Maybe in the ServerLayout section something is wrong, but I have found many 
example configurations like this.

 Now when I am going to use Gimp it also sees the movement and it sees the
 different tools (i.e. eraser and pen) but it nearly never sees the pressure.

Often folks forget to turn XInput on. They have windowing systems that
automagically convert pressure tablet events into plain old X-Y mouse
events, throwing pressure and tilt evaluators away.

To ask for unadulterated tablet events

right-mouse-button-Dialogs-Input Devices...
Select wacom Device
Select Mode (screen maps the tablet rectangle to the entire screen; window maps it to
the Gimp canvas window)

Many Gimpers use Linux and the XFree86 X-Window system
and GTK+ has built-in prejuduces for this combination. This environment
has tablet drivers that pack the valuators in X-Y-Pressure-X_Tilt-Y_Tilt
order. Your environment may vary from this ordering. The Axis tab
allows you to experiment with this ordering. X  Y are almost universally
first, but the remaining parameters can vary.

These options not offered? No options offered?
Check if the tablet is properly configured for XInput devices.
You will likely have to look at Wacom and your X Window system
(Or Windows literature -- you've given no hint about your hardware)

Possibly your GTK+ package was not built with XInput enabled. Look
in the config.status for a line like

--with-xinput=xfree (options: xfree | xid)

 As anybody a idea what this might be?

Those are mine. Hope they are of some help.

Be good, be well

[Gimp-user] Wacom works but Gimp misses pressure

2001-07-12 Thread Michael Guse

Hi there !

I have installed a Wacom Intuos tablet on my machine. I have tested the 
installation with the little xinput tool and I see X/Y movements and pressure 
and tilt values. All values are changing as I expect them to do.
Now when I am going to use Gimp it also sees the movement and it sees the 
different tools (i.e. eraser and pen) but it nearly never sees the pressure.
This means that I am pressing the pen until it breaks but Gimp still says 
that I am just moving the pen without touching the board.
Only sometimes it suddenly sees the pressure and then it works until I lift 
the pen and the pressure gets back to 0 after that no pressure is seen for a 
long time.

As anybody a idea what this might be?
