1. Nice tute Ben. Useful for a newbie to Ubuntu like myself. Do you have any idea how to swap the default right/middle buttons on the pen as I prefer the opposite?

   cheers…

   • Yeah sure:

     xsetwacom --get "Wacom Intuos3 9x12 stylus" Button 3

     Will tell you what say button three is mapped to for your stylus. The buttons 1, 2, 3 correspond to mouse clicks left, middle, right, so to switch buttons two and three just do:

     xsetwacom --set "Wacom Intuos3 9x12 stylus" Button 3 2
xsetwacom --set "Wacom Intuos3 9x12 stylus" Button 2 3

     Obviousy swap the device name for your stylus.

2. oooh, i have years trying to do this, thanks a lot

3. Thanks for your useful post! For those with an nvidia card handling their dual desktop with nvidia-settings installed, to save working out the transformation matrix each time, I use awk to pass the output of:

   nvidia-settings -q FrontendResolution

   # Whole desktop
   xinput set-prop “Wacom BambooFun 4×5 stylus” –type=float “Coordinate Transformation Matrix” 1 0 0 0 1 0 0 0 1

   # Screen 1
   xinput set-prop “Wacom BambooFun 4×5 stylus” –type=float “Coordinate Transformation Matrix” `nvidia-settings -q FrontendResolution | awk ‘/Attribute.*:/{print $7}’ | awk ‘BEGIN{FS=”[,.\n]”; RS=””}{$6=$1/($1+$4); $2 $4 $5; print $6″ 0 0 0 1 0 0 0 1″ }’`

   # Screen 2
   xinput set-prop “Wacom BambooFun 4×5 stylus” –type=float “Coordinate Transformation Matrix” `nvidia-settings -q FrontendResolution | awk ‘/Attribute.*:/{print $7}’ | awk ‘BEGIN{FS=”[,.\n]”; RS=””}{print $4/($1+$4)” 0 “$1/($1+$4)” 0 1 0 0 0 1″ }’`

4. Thank you for this post!

   I discovered the option “MapToOutput” of xsetwacom.
   First I used the command “xrandr” to get the names of my monitors (when both are plugged).
   Then I use the names in the xsetwacom command like this :

   #! /bin/sh
   xsetwacom set “Wacom Intuos3 9×12 eraser” MapToOutput VGA1
   xsetwacom set “Wacom Intuos3 9×12 stylus” MapToOutput VGA1

   Then I map this script to the ubuntu key, like you explain.

5. Thanks Ben and co, this sorted me out a treat.
   A limitation of the original post is issuing multiple xsetwacom commands so that the eraser can also be mapped.

   My setup = Ubuntu 11.04 6×8 Intuos3 two 1280×1024 displays.

   I created 4 files as follows in the users home directory:-
   wacom-left containing:-
   #!/bin/sh
   xinput set-prop “Wacom Intuos3 6×8 stylus” –type=float “Coordinate Transformation Matrix” 0.5 0 0 0 1 0 0 0 1
   xinput set-prop “Wacom Intuos3 6×8 eraser” –type=float “Coordinate Transformation Matrix” 0.5 0 0 0 1 0 0 0 1

   wacom-right containing:-
   #!/bin/sh
   xinput set-prop “Wacom Intuos3 6×8 stylus” –type=float “Coordinate Transformation Matrix” 0.5 0 0.5 0 1 0 0 0 1
   xinput set-prop “Wacom Intuos3 6×8 eraser” –type=float “Coordinate Transformation Matrix” 0.5 0 0.5 0 1 0 0 0 1

   wacom-both containing:-
   #!/bin/sh
   xinput set-prop “Wacom Intuos3 6×8 stylus” –type=float “Coordinate Transformation Matrix” 1 0 0 0 1 0 0 0 1
   xinput set-prop “Wacom Intuos3 6×8 eraser” –type=float “Coordinate Transformation Matrix” 1 0 0 0 1 0 0 0 1

   I then added the left, both, and right to Shifts of: Print Scr, Scroll Lock, and Pause like in the original post.

   N.B. I needed to put in the full path of the command so if user was fred then for command I had to put in:-
   /home/fred/wacom-left

   To auto associate these keyboard shortcuts with wacom pad buttons as in original post I created another file in the users home dir:-
   wacom-buttons containing:-
   #!/bin/sh
   xsetwacom –set “Wacom Intuos3 6×8 pad” Button 1 “key Shift Pause”
   xsetwacom –set “Wacom Intuos3 6×8 pad” Button 3 “key Shift Print”
   xsetwacom –set “Wacom Intuos3 6×8 pad” Button 2 “key Shift Scroll_Lock”

   I then made all the wacom command files executable:-
   chmod u+x ~/wacom-*

   Finally added in startup applications wacom-buttons, again taking care to put in the whole path for the wacom-buttons file or use the browse button; ~ didn’t work for me.

   Thanks again everyone, very helpful.

   @Steven
   This looked like a great and clever fix but alas for me using twinview nvidia-settings -q FrontendResolution returns no info.

   @Michael
   re the great option of MapToOutput was not available to me, see:-
   http://ubuntuforums.org/showthread.php?t=1656089
   Only in recent git of xf86-input-wacom is this working for proprietary nvidia drivers.

6. THANK YOU!!!!

7. Thanks a lot!

8. here’s what I wrote for the Huion tablet, and it should work similarly for any tablet.
   http://pastebin.com/QE8NCkP0
   you just edit the script with the names of your adapter ports, and put in the tablet name. I wrote it for my 3 monitor setup.

9. Nice script, Christopher Barry. I made a similar one that I find a little bit easier to use. It’s a little simpler and there is no need to modify the script to get it to work with your particular tablet or screens. When run with no arguments, it resets your tablet to cover all desktops.

   [On the other hand, my script doesn’t have clever functions like your evar which evaluates the contents of a variable as another variable name.]

   
   #!/bin/bash
   # BW 2015
   
   # mapwacom: Given an xrandr output screen name, e.g., "DVI-I-1",
   # restrict any wacom tablets (or any other device with the word
   # "tablet" in its name) to that one screen. If no output screen is
   # given, all tablets will be reset to the default, covering all
   # screens on the desktop.
   
   # Output names can be specified in lowercase and truncated.
   
   # Examples:
   
   #   $ mapwacom foo
   #     Error: foo not valid. Please pick a connected output instead.
   #     DVI-I-1 connected
   #     HDMI-1 disconnected
   #     VGA-1 connected
   
   #   $ mapwacom VGA-1
   #     xinput --map-to-output 13 VGA-1
   #     xinput --map-to-output 14 VGA-1
   #     xinput --map-to-output 15 VGA-1
   
   #   $ mapwacom vga (same as above)
   
   #   $ mapwacom v   (also same as above)
   
   #   $ mapwacom d
   #     xinput --map-to-output 13 DVI-I-1
   #     xinput --map-to-output 14 DVI-I-1
   #     xinput --map-to-output 15 DVI-I-1
   
   #   $ mapwacom
   #     Resetting all Wacom devices to cover entire desktop
   
   
   
   showoutputs ()
   {
       echo "Error: $output not valid. Please pick a connected output instead."
       xrandr | grep -o '^.*connected'
       exit 1
   }
   
   
   if [ -z "$1" ]; then
       echo "Resetting all Wacom devices to cover entire desktop"
       output="desktop"
   else
       output="$1"
       connected=$(xrandr | grep -i -- "^$output.* connected") || showoutputs
       set $connected
       output="$1"
   fi
   

10. 
    xinput --list --name-only | egrep -i 'wacom|tablet' \
        | while read dev;
          do
    	  id=$(xinput --list --id-only "$dev")
    
    	  if [[ "$output" != "desktop" ]]; then
    	      echo xinput --map-to-output $id $output
    	      xinput --map-to-output $id $output
    	  else
    	      # Xsetwacom allows map-to-output desktop, but xinput does not.
    	      # So, for now, we will do an ugly workaround. :P
    	      prop=$(xinput --list-props $id \
    			    | grep -o "Coordinate Transformation Matrix.*:" \
    			    | egrep -o '[[:digit:]]*')
    	      [ "$prop" ] && xinput --set-prop $id $prop  0 0 0  0 0 0  0 0 0
    	  fi
          done
    

11. Great, it works fine for me. But How I can save this settings? This do not work after restart.
