      Some people say that i need to do
      "open the configuration file with
      sudo nano /etc/init.d/triggerhappy
      modify the configuration file line to look like the following
      DAEMON_ARGS="--daemon --triggers /etc/triggerhappy/triggers.d/ --socket /var/run/thd.socket --pidfile $PIDFILE --user pi /dev/input/event*" "

      previously it was : "
      DAEMON_ARGS="--daemon --triggers /etc/triggerhappy/triggers.d/ --socket /var/run/thd.socket --pidfile $PIDFILE --user nobody /dev/input/event*"

      But i did it previsouly before asking for help on this forum so i guess i'm missing something !

            Now that TriggerHappy seems to be "running well", i think we're close to make it work !
            Poorly, when i press the button, nothing seems to be happening...

                No, it's still not working:

                • User running the service seems to be still nobody - probably the configuration file I mentioned works only for the old style service file
                • You get an error in the configuration file, which means it's running but ignoring your config.

                I think your best bet is to disable the service and run it as the pi user from the autostart.sh file (where Emulationstation is started).
                Run it from the terminal, as the pi user with

                /usr/sbin/thd --triggers /etc/triggerhappy/triggers.d/ --deviceglob /dev/input/event*
                

                Make sure it works like this - i.e. it gets your button inputs correctly. Then, add the line in either /etc/rc.local or in the autostart.sh script. Make sure you add an & at the end of the command when adding it to either file.

                  Waaa we're so close now !!
                  So when i type
                  "/usr/sbin/thd --triggers /etc/triggerhappy/triggers.d/ --deviceglob /dev/input/event*" from the terminal and press my button, it actually works !

                  Now i'm not sure when to add the line, should i do "sudo nano /etc/rc.local" and go at the end and copy and paste ?

                  FYI, when i type "sudo nano autostart.sh" the file is empty

                    @djon The autostart.sh file is in /opt/retropie/configs/all/autostart.sh, but try with /etc/rc.local first. You'll need to reboot to test it.

                        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

                            @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 (```).

                                    @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.
