I've got a script that is executed in order to have suspending/resuming working in my laptop. Then I have another series of xinput,xkbset and xmodmap commands that are executed when I initiate a session to have two-finger scrolling and keyboard shortcuts set up. When I resume from suspend, two-finger scrolling and my keyboard shortcuts won't work. I need to manually execute the commands in the second file again. How can I add those to the suspend/resume script to have this done automatically? See below:

You can place your scripts in the /etc/pm/sleep.d directory to have them run after suspend. You will need to add a conditional to make your script run only during resume and not during the suspend process as well. For example, your touchpad script would look like:

case "${1}" in

    resume|thaw)

        DISPLAY=:0.0 ; export DISPLAY

        xinput set-int-prop "SynPS/2 Synaptics TouchPad" "Two-Finger Scrolling" 8 1

        xinput set-int-prop "SynPS/2 Synaptics TouchPad" "Synaptics Two-Finger Scrolling" 8 1 1

        xinput set-int-prop "SynPS/2 Synaptics TouchPad" "Synaptics Two-Finger Pressure" 32 10

        xinput set-int-prop "SynPS/2 Synaptics TouchPad" "Synaptics Two-Finger Width" 32 8

        setxkbmap -layout gb

        xkbset m

        xkbset exp =m

        su $USER -c "sleep 3; /usr/bin/xmodmap -e "keycode 135 = Pointer_Button2"" &

Be sure your script is marked globally executable and change $USER to the corresponding username.

You can find more detailed information in the pm-suspend manpage (man pm-suspend) or by looking at the documentation in /usr/share/doc/pm-utils (particularly /usr/share/doc/pm-utils/HOWTO.hooks.gz).

On Ubuntu 16.04 I had to create service this way:

1. 
   

   create file

   
   
   

   sudo gedit /etc/systemd/system/somename.service
   
   

   
   


2. 
   

   put inside

   
   
   

   [Unit]
   
   Description=Some description
   
   Before=sleep.target
   
   StopWhenUnneeded=yes
   
   
   
   [Service]
   
   Type=oneshot
   
   RemainAfterExit=yes
   
   ExecStop=-/path/to/your/script.sh
   
   
   
   [Install]
   
   WantedBy=sleep.target
   
   

   
   


3. 
   

   enable service

   
   
   

   sudo systemctl enable somename
   
   

   
   


4. 
   

   (optional) if not working after resume from suspend > check for errors with

   
   
   

   journalctl -u somename.service
   
   

   
   

Open this file:

sudo vim /lib/systemd/system-sleep/hdparm

Contents:

#!/bin/sh



case $1 in 

  post)

    /usr/lib/pm-utils/power.d/95hdparm-apm resume

    ## Paste your command to run your script

    ;; esac

Your command will execute with admin privileges.
