How to script a process upon wake up on Ubuntu

IRJ

Create a new file in /etc/pm/sleep.d

vi /etc/pm/sleep.d/bluetooth_restart

Add the following contents to the file. You will want to replace sudo service restart bluetooth section with your own commands or point to your own script

#!/bin/sh
case "$1" in
    thaw|resume)
        sudo service bluetooth restart
        ;;
esac

Now when you system wakes up it will automatically perform this action.

You could just modify the bluetooth.service to have this :

[Unit]
...
`After=suspend.target hibernate.target hybrid-sleep.target`

...

[Install]
WantedBy=suspend.target hibernate.target hybrid-sleep.target

What file are you using?

This is what I found /etc/systemd/system/bluetooth.taget.wants/bluetooth.service
