      @djon Well, it's clear why this fails: the service doesn't run as root AND the user used to run the service does not have sudo passwordless access. You can see the normal sudo disclaimer in the logs (We trust you have received the usual lecture from the local System..), which is shown whenever a user runs sudo and it must provide the password to run privileged commands. Since your service cannot provide the password, the sudo commands fail.

      Configure the service to run as rootor as the user pi, and you won't have any problems.

          Well it looks promising thanks !

          Luckily, this is configurable. Edit the /etc/default/triggerhappy file and uncomment (remove the # ) from the last line. Restart the service via sudo systemctl restart triggerhappy and it should run as root, so you don't need sudo for executing commands.

          You can also modify the last line and make it run as the pi user (which should be able to run sudo commands without a password prompt), I'd recommend doing that instead of leaving it running as root.

            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

                              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 (```).

                                          @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.
