Juho Vepsäläin has made some enhancements to the tablet-apps program which can be downloaded from here. The improved code fixes tilt support and adds support for devices with wheels e.g. the airbrush. Copy the files in this archive over the top of the ones from the main version to try it out.

Xorg config for Wacom tablets

Ubuntu should come with the correct Xorg config file but if it doesn't then here are the relevant bits from my setup for a USB Graphire tablet:

Release 0.3.1

Added some more padding around the widgets and made the drawing test area much more responsive (now with infinite circles!)

I have also removed the check for the location of xsetwacom so it should now work no matter where it is on your $PATH. However you must install a more recent version of wacom-tools than what edgy currently ships as its version does not support the "get" command used to determine the current values of various propertys.

Here's the latest screenshot:

Release 0.3

Lots of feedback from various people, and the most common suggestion seems to be that the control center applet is too long and not very HIG compliant.

This version moves the drawing test area over to the right hand side of the screen and slightly fixes the pressure curve widget so that it draws all of the grid properly and shows the control points in a more noticeable colour.

Here is a new screenshot of the application:

Small fix to the class syntax so it runs on python 2.4 (and therefore ubuntu edgy as well as feisty), thanks Tom!

Release 0.2

I've split the functionality up into two seperate apps. One is a gnome control center applet for configuring graphics tablet devices, the other is a little panel applet that shows pressure of any pressure sensitive XInput device

I've also been informed of the Art Libre set of tango flavoured icons, which includes a nice graphics tablet icon that I use for both the panel and control center applets.

The control center applet shows the pressure curve and click force for any wacom device using the xsetwacom program. Changing the pressure curve or the input mode takes place in real time. Changes are not yet saved, so logging out or rebooting will reset your preferences to whatever is set in your xorg.conf file.

The panel applet looks the same only it now uses the new icon:

Release 0.1

The gnome wacom applet is a small gnome panel applet that shows how much pressure is being applied to your wacom tablet by the current device. Clicking on the panel icon brings up a dialog allowing you to select a different device and check what pressure and tilt information is being recieved from it. This dialog also contains a small drawing test area to give your pen a quick test.

Installation:
sudo apt-get install python-gnome2 python-gnome2-desktop
sudo dpkg -i gnome-wacom-applet_0.1-0_i386.deb

The next version will add support for altering the pressure curve and maybe changing between relative and absolute modes -- the basic idea is just to make this a graphical front end to xsetwacom.

I only have a graphire tablet so I'm unable to test if the tilt information is being displayed properly. If I ever get hold of one I'll probably update the applet to show the tilt using a more interesting custom widget and make the drawing area give some kind of visual feedback on tilt as well.

The panel applet looks like this:

And the Dialog box looks like this:
