Mapping a Wacom Tablet to one specific monitor
When a Wacom Tablet is plugged into a Linux Computer with multiple screens, it is being mapped to all of them which makes it hard to write. Here is how to map it to one particular screen:
BUT: This way works only for xorg. If you are running wayland, you can configure these settings with "libinput". Some Desktop Environments do even have a GUI programm in their Wayland Version, which is specifically made to handle the libinput stuff for you! GNOME has full support for configuring buttons and mapping the tablet to a monitor. KDE Plasma has full support for configuring buttons and mapping the tablet to a monitor. You can read more about this here.
$ xinput
The output should look somewhat like this:
[user@host ~]$ xinput
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ bcm5974 id=12 [slave pointer (2)]
⎜ ↳ SINO WEALTH Thunderobot KG3089 Consumer Control id=13 [slave pointer (2)]
⎜ ↳ SINO WEALTH Thunderobot KG3089 Mouse id=18 [slave pointer (2)]
⎜ ↳ Logitech G305 id=19 [slave pointer (2)]
⎜ ↳ Wacom One by Wacom S Pen Pen (0) id=22 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Power Button id=8 [slave keyboard (3)]
↳ Lid Switch id=9 [slave keyboard (3)]
↳ Sleep Button id=10 [slave keyboard (3)]
↳ Apple Inc. Apple Internal Keyboard / Trackpad id=11 [slave keyboard (3)]
↳ SINO WEALTH Thunderobot KG3089 Consumer Control id=14 [slave keyboard (3)]
↳ SINO WEALTH Thunderobot KG3089 Keyboard id=15 [slave keyboard (3)]
↳ SINO WEALTH Thunderobot KG3089 System Control id=16 [slave keyboard (3)]
↳ SINO WEALTH Thunderobot KG3089 id=17 [slave keyboard (3)]
↳ Logitech G305 id=20 [slave keyboard (3)]
↳ Wacom One by Wacom id=21 [slave keyboard (3)]We can see that in this case, the Wacom Tablet has the ID "21", and the pen of the tablet has the ID "22".
The next thing we want to do is finding out the name of the screen we want the tablet to be mapped to. We can do that by executing:
$ xrandr
The output should look somewhat like this:
[user@host ~]$ xrandr

DP-2 disconnected (normal left inverted right x axis y axis)
HDMI-2 disconnected (normal left inverted right x axis y axis)We now see all of our screens connected to the Computer. We can also see our primary monitor which we want the tablet to be mapped to:
HDMI-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 521mm x 293mm
Now we have all information needed to map the Wacom tablet to our primary screen only. Let's do it:
$ xinput map-to-output "penID" "name-of-screen"
For my example the command would look like this:
$ xinput map-to-output 22 HDMI-1
Congratulations! You now mapped your Wacom Tablet to one specific monitor! Happy writing, happy drawing!
