+  I made a small and quick utility to set up my Wacom tablet so it is only bound
+  to one screen. This is a fish script, so let’s insert the sheband.

+   Let’s first declare our function that will be called to set our variables.
+   #+BEGIN_SRC fish
+   function set_device
+   #+END_SRC
+
+   We need some variables in order to correctly set our tablet. First, let’s get
+   declare what the name of our tablet is, and what the name of its touchpad is.
+   #+BEGIN_SRC fish
+     set -g DEVICE "Wacom USB Bamboo PAD Pen stylus"
+     set -g DEVICETOUCH "Wacom USB Bamboo PAD Finger touch"
+   #+END_SRC
+
+   We will also  modify two settings: the  speed of the cursor  on the touchpad,
+   and the scroll speed. Let’s declare the name of these two settings.
+   #+BEGIN_SRC fish
+     set -g WACOMPROPTOUCHSPEED "Device Accel Velocity Scaling"
+     set -g WACOMPROPSCROLLPSEED "ScrollDistance"
+   #+END_SRC
+
+   To get the correct values for the area  it can cover, we’ll need to reset our
+   tablet.
+   #+BEGIN_SRC fish
+   xsetwacom set "$DEVICE" ResetArea
+   #+END_SRC
+
+   Now we can get the X and Y areas.
+   #+BEGIN_SRC fish
+     set -l AREATOT (xsetwacom get "$DEVICE" Area)
+     set -g AREAX (echo $AREATOT | awk '{print $3}')
+     set -g AREAY (echo $AREATOT | awk '{print $4}')
+   #+END_SRC
+
+   Now let’s close our function.
+   #+BEGIN_SRC fish

+   This function will allow us to select  the screen on which the tablet will be
+   active.  We can  also select  the option  “desktop” so  that all  screens are
+   selected. Let’s declare our function.
+   #+BEGIN_SRC fish
+   function set_screen
+   #+END_SRC
+
+   First, let’s set what screens are available, including the desktop option.
+   #+BEGIN_SRC fish
+     set CONNECTED_DISPLAYS (xrandr -q --current | \
+     sed -n 's/^\([^ ]\+\) connected .*/\1/p') desktop
+   #+END_SRC
+
+   Now, let’s select the one we wish to use using rofi.
+   #+BEGIN_SRC fish
+     set -g SCREEN (for d in $CONNECTED_DISPLAYS
+         echo $d
+     end | rofi -dmenu -i -p "Select your dispaly" | tr -d '\n')
+   #+END_SRC
+
+   Now, let’s get the resolution of our selected screen.
+   #+BEGIN_SRC fish
+     set -l LINE (xrandr -q --current | if [ "$SCREEN" = "desktop" ]
+         sed -n 's/^Screen 0:.*, current \([0-9]\+\) x \([0-9]\+\),.*/\1 \2/p'
+     else
+         sed -n "s/^$SCREEN"' connected \(primary \)\{0,1\}\([0-9]\+\)x\([0-9]\+\)+.*/\2 \3/p'
+     end)
+   #+END_SRC
+
+   From that, let’s get the vertical and horizontal resolution of our screen.
+   #+BEGIN_SRC fish
+   echo $LINE | read -g WIDTH HEIGHT
+   #+END_SRC
+
+   If any of our =WIDTH= ou =HEIGHT= it empty, we’ll have to abort the script.
+   #+BEGIN_SRC fish
+     if test -z $WIDTH || test -z $HEIGHT
+         exit 1
+     end
+   #+END_SRC
+
+   Let’s close our function now.
+   #+BEGIN_SRC fish
+   end
+   #+END_SRC
+
+** Adjust the tablet
+   :PROPERTIES:
+   :CUSTOM_ID: h-7e7bcdd1-dce8-43aa-b26e-cc4f38be2a1b
+   :END:
+   This function  will take care  of adjusting our  tablet to our  screen. Let’s
+   declare our function.
+   #+BEGIN_SRC fish
+   function adjust_device
+   #+END_SRC
+
+   If our screen is too high or too  wide for our tablet, we will have to adjust
+   the  height or  width  of the  area  used by  the tablet.  So  let’s get  the
+   theoretical new height and width of the area.
+   #+BEGIN_SRC fish
+     set RATIOAREAY (math ceil \($AREAX \* $HEIGHT \/ $WIDTH\))
+     set RATIOAREAX (math ceil \($AREAY \* $WIDTH \/ $HEIGHT\))
+   #+END_SRC
+
+   Now,  if  the  current height  of  the  tablet’s  area  is greater  than  the
+   theoretical new  area, it means the  current area is too  high. Otherwise, it
+   should be the other way around. Let’s set =NEWAREAX= and =NEWAREAY= that will
+   be used to set the new area for the tablet.
+
+   #+BEGIN_SRC fish
+     if test $AREAY -gt $RATIOAREAY
+         set -g NEWAREAX $AREAX
+         set -g NEWAREAY $RATIOAREAY
+     else
+         set -g NEWAREAX $RATIOAREAX
+         set -g NEWAREAY $AREAY
+     end
+   #+END_SRC
+
+   Alright, now let’s set the new area with these new variables.
+   #+BEGIN_SRC fish
+     xsetwacom set "$DEVICE" Area 0 0 $NEWAREAX $NEWAREAY
+     xsetwacom set "$DEVICE" MapToOutput "$SCREEN"
+   #+END_SRC
+
+   Let’s slow down the cursor’s speed on the touchpad.
+   #+BEGIN_SRC fish
+   xinput set-float-prop $DEVICETOUCH $WACOMPROPTOUCHSPEED 0.5
+   #+END_SRC
+
+   Let’s also slow down the scroll speed of the touchpad.
+   #+BEGIN_SRC fish
+     xsetwacom set $DEVICETOUCH $WACOMPROPSCROLLPSEED "90"
+   #+END_SRC
+
+   Now, let’s close the function.
+   #+BEGIN_SRC fish
+   end
+   #+END_SRC
