Linux

To install the wacom tablet under linux, simply plug it in and run the shell script you find under ...

The shell script can be used to personalize the buttons and other options. 

   1 # Defining the Buttons 1-4 on the pad. With this config the first button presses 1 on your keyboard.
   2 # Note that the first Button is "3" not "1", etc. 
   3 xsetwacom set "Wacom Intuos PT M Finger pad" Button 3 "key 1"
   4 xsetwacom set "Wacom Intuos PT M Finger pad" Button 1 "key 2"
   5 xsetwacom set "Wacom Intuos PT M Finger pad" Button 9 "key 3"
   6 xsetwacom set "Wacom Intuos PT M Finger pad" Button 8 "key 4"

As you can see from the config, the Button config isn't 1 2 3 4 but 3 1 9 8. This has to do with how the kernel maps the input buttons, that can't be changed. At the end you write in the actual input you want, the standard config is for use with MyPaint, with it you can easily switch between 4 colors. You could also map different functions on it, with "key ctrl+ z ctrl-" for instance, the button will push and hold down the control button on your keyboard and press Z before it releases ctrl again. If you would input "key ctrl z" the programm does the keystrokes after each other.

If you want to activate the control with touch additionally to the pen, add following line: 

   1 xsetwacom set "Wacom Intuos PT M Finger touch" Gesture "on"

If you want to reset the controls to default, just unplug the Wacom Tablet and plug in the USB again.

Windows & Mac

Under Windows & Mac the standard Wacom drivers can be used to set up the buttons and other options.

Software

MyPaint

MyPaint is a simple Program that lets you draw on fullscreen. To setup the colors on the hotkeys 1-0 simply select any color you want in the programm and press CTRL + (1-0) Key. After you have saved the colors you want, you can select them by pressing 1-0.

Kazam

You will find Kazam pre installed on linux under Applications → Sound & Video → Kazam. As soon as you open it, you will see following dialogue: <<br>> kazam1.png<<br>> The standard Settings are correct for most uses, it captures the whole screen and at the end of the capture it lets you choose where you want to save the file.
