      If you're launching the emulators from a desktop session, you don't need xinit. sudo should never be used to start an emulator.

      Otherwise, if you'd like an emulator to start a Xorg/desktop session before launch then prefix the emulator entry with XINIT: in the emulators.cfg file where the emulator is defined (see minecraft for an example).

        @mitu and if I haven't file config of emulator ?
        My solution is to edit in retropie the es_systems.cfg changing the line between <command> </command>
        This is the command in my youtube video:
        From minute 8:10 to 9:00:
        <command>cd /home/pi/games/ppsspp sudo xinit ./ppssppsdl %ROM%</command>
        Now I will try to replace "sudo xinit" to
        XINIT: ...leaving the rest of the command unchanged...

          Install the emulator included RetroPie-Setup and that file will be automatically created; you don't need to modify es_systems.cfg. Add an entry for your Vulkan-enabled version in emulators.cfg (prefixed with XINIT: if needed) and you'll be able to choose between the 2 versions from the runcommand launch menu.

            Tried but If I Replace "sudo xinit" with
            XINIT:
            this command not exist on retropie...

            My emulators like Sega Supermodel3 and ppssppsdl runs under emulationstation only with "sudo xinit" ...and the rest of the command...

              It's not a command, it's an option for runcommand telling it to run the program in a desktop/Xorg session.

                @mitu maybe we talk of 2 different things...
                The emulator /ppssppsdl that support vulkan driver isn"t present in retropie setup...
                This special emulator is installed by pikiss...not by retropie...
                So i have Created a new system in es_systems.cfg
                Otherwise is impossible to launch it on emulationstation ...

                  Almost. You don't seem to be familiar with how RetroPie configures emulators, though.

                  The emulator /ppssppsdl that support vulkan driver isn"t present in retropie setup...

                  Yes, that's why I said earlier:

                  Add an entry for your Vulkan-enabled version in emulators.cfg (prefixed with XINIT: if needed) and you'll be able to choose between the 2 versions from the runcommand launch menu.

                  Installing the RetroPie entry for ppsspp will create the emulators.cfg, which you can modify an add your own entry (for the Vulkan enabled PPSSPP):

                  ppsspp-vulkan=XINIT:/home/pi/games/ppsspp/ppssppsdl %ROM%
                  

                  You can then, as said earlier:

                  ..you'll be able to choose between the 2 versions from the runcommand launch menu.

                      Install the ppsspp emulator included in RetroPie (it's in the optional package section), just like any other emulators you install from RetroPie-Setup - https://retropie.org.uk/docs/Updating-RetroPie/#manage-packages.
