Limit a graphics tablet to one monitor

Solution 1:

Expanding on this post: HUION H610 Tablet

I'll provide a nice little script for the HUION H420 at the bottom that you can create.

To determine your monitors you can run the command: xrandr

Out put should look like:

Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 16384 x 16384
DVI-I-0 disconnected (normal left inverted right x axis y axis)
DVI-I-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 477mm x 268mm
   1920x1080     60.00*+
   1680x1050     59.95  
   1600x1200     60.00  
   1600x900      60.00  
   1440x900      59.89  
   1400x1050     59.98  
   1280x1024     75.02    60.02  
HDMI-0 disconnected (normal left inverted right x axis y axis)
DP-0 disconnected (normal left inverted right x axis y axis)
DVI-D-0 disconnected (normal left inverted right x axis y axis)
DP-1 disconnected (normal left inverted right x axis y axis)

The DVI-I-1 connected primary 1920x1080+0+0 is the line we are interested in, specifically the DVI-I-1

One more piace of information is needed, the id number of the stylus. This can be found by running the command xinput

In my case it returns:

   ↳ HUION H420 Pen stylus                      id=20   [slave  pointer  (2)]
   ↳ HUION H420 Pad pad                         id=21   [slave  pointer  (2)]

To get the tablet to work on only that monitor you can run the command:

xinput map-to-output 20 DVI-I-1

To wrap this in a script with buttons you can create a file with your favorite text editor, tablet.sh that looks like:

#!/bin/sh

#Change DVI-I-1 to what monitor you want from running command: xrandr
MONITOR="DVI-I-1"
PAD_NAME='HUION H420 Pad pad'

#undo
xsetwacom --set "$PAD_NAME" Button 1 "key +ctrl +z -z -ctrl" 

#define next 2 however you like, I have mine mapped for erase in krita
xsetwacom --set "$PAD_NAME" Button 2 "key e"
xsetwacom --set "$PAD_NAME" Button 3 "key h"

ID_STYLUS=`xinput | grep "Pen stylus" | cut -f 2 | cut -c 4-5`

xinput map-to-output $ID_STYLUS $MONITOR

exit 0

now chmod +x tablet.sh and then run the command ./tablet.sh

If using the script, the MONITOR variable needs to be changed, and you can change what you want the buttons to do.

There is a project that actually has a gui for the monitor and drawing tablet setup. http://wenhsinjen.github.io/ptxconf/

The above solution did not work for me (but it was really close). I had to change this line

ID_STYLUS=`xinput | grep "Pen stylus" | cut -f 2 | cut -c 4-5`

to this:

ID_STYLUS=$(xinput | grep "Pen stylus" | cut -f 2 | cut -c 4-5)

That fixed it.

The script also failed because my monitor was VGA-2 when I wrote the script, but when I restarted my machine, the same monitor was assigned to VGA-1. I replaced this:

MONITOR='VGA-2'

With

MONITOR= $(xrandr | grep "VGA" | grep -w "connected" | cut -c 1-5)
