      So i did : sudo nano /etc/rc.local
      And added at the end of the file
      "/usr/sbin/thd --triggers /etc/triggerhappy/triggers.d/ --deviceglob /dev/input/event* &"
      Then sudo reboot

      But it still not working

          @djon Does the process shows up when your run ps -ef from the terminal ?
          EDIT: Yes, of course you need to add it before the exit, otherwise it's not executed.

            Ok so i add it before "exit 0" this time and run ps -ef @mitu
            And i think the line you're interested in is
            "nobody 364 1 0 03:26 ? 00:00:00 /usr/sbin/thd --triggers /etc/triggerhappy/triggers.d/ --socket /run/thd.socket --user nobody --deviceglob /dev/input/event*"

              @djon Doesn't seem to be correct. Have you disabled the service ? The process shown there seems the one started from the built-in service script. Post your rc.local file contents, surrounded by code tags (```).

                # rc.local
                
                #
                
                # This script is executed at the end of each multiuser runlevel.
                
                # Make sure that the script will "exit 0" on success or any other
                
                # value on error.

                _IP=$(hostname -I) || true
                
                if [ "$_IP" ]; then
                
                  printf "My IP address is %s\n" "$_IP"

                exit 0

                  @djon Just change it to

                  # Start THD as user pi
                  nohup /usr/sbin/thd --triggers /etc/triggerhappy/triggers.d/ --user pi --deviceglob /dev/input/event* &
                  
                  exit 0
                  

                  and reboot. Disable the service with sudo systemctl disable triggerhappy first.

                      Okay so i made the mistake to erase all the file, to put just your line...
                      So i did it again, with just your line at the end, and i can say... that... it is workinggggggggggg !!!!!!! @mitu

                      I think that i will start again from stratch with a brand new retropie image, next time i'll just need to put :

                      # Start THD as user pi
                      nohup /usr/sbin/thd --triggers /etc/triggerhappy/triggers.d/ --user pi --deviceglob /dev/input/event* &
                      
                      exit 0
                      

                      Or i'll need to take all the steps we made ?

                        Since you're here @mitu and that your the best guy ever, i need to change a bit the script to make the brightness increase by 25% each time, i was thinking :

                        sudo chmod 777 /sys/class/backlight/rpi_backlight/brightness && echo 25% > /sys/class/backlight/rpi_backlight/brightness
                        

                        ... hum no i just test it and they say "invalid argument"

                        FYI the brightness can go from 0 to 250

                          I ran into the same issue trying to get triggerhappy to process the VOLUME_UP and VOLUME_DOWN events from my Dell AC511 soundbar.

                          No matter whether I set the user to run the process as in /etc/defaults/triggerhappy, or /etc/init.d/triggerhappy, it would always run as user nobody.

                          The process would run, but because nobody doesn't have privileges, my commands to amixer would not run.

                          The solution I found was to edit /etc/systemd/system/multi-user.target.wants/triggerhappy.service and set the user in there to pi.

                          After doing that and restarting the daemon, the triggerhappy process ran under user pi and everything worked.

                          Edit: Future updates my overwrite changes to this file, I don't know.
