      @windg Any information if it is planned to be fixed?
      I gathered information and understand that every problem with all of this is because of the new video driver KMS that's going to be standart.

      So, as far as I have gathered, Pi5 and Bookworm requires KMS driver and FKMS is not supported anymore.

      KMS doesn't have a way to change between 480i Emulationstation and 240p in emulators, change overscan settings and all the nice options that FKMS had?

      So, if you have a CRT TV, then Raspberry Pi 5 is a paperweight? 🫠

        Yes, althought the change happened for all Pi models since RaspiOS Bullseye - almost 3 2 years ago .

        KMS doesn't have a way to change between 480i Emulationstation and 240p in emulators, change overscan settings and all the nice options that FKMS had?

        Not even fkms had this reliably, like in the non-KMS scenarious where tvservice was working reliably.

        No, but don't expect the same level of support as for digital HDMI. You should post your questions in the RPI forums, you'd get better answers there.

          Hello!

          I'm struggling with setting retropie retroarch resolution.
          I left emulationstation on resolution 704x432, but I want retroarch to always start with resolution 720x240.
          No matter how I try to save this resolution in retroarch.cfg, it doesn't load on start.

          What should I do for retroarch to always start with resolution 720x240?
          With tvservice I had onstart and onend codes, but I don't know and can't find what codes work for KMS.

            Is this your current resolution ? You can't just pick an arbitrary resolution if it's not supported by the current video driver.

            FWIW runcommand is responsible for switching/setting the resolution and will save it to /dev/shm/retroarch.cfg and then pass it on to RetroArch.

            With tvservice I had onstart and onend codes, but I don't know and can't find what codes work for KMS.

            There are none, there's no tvservice-like utility for KMS/DRM, each application has to implement video resolution

              @mitu It's a supported resolution. I can change to it in retroarch settings. The problem is that there's no option (as fas as I can find) in Retropie to determine different resolutions for emulationstation and retroarch.

              I'll try to make it more clear - i want emulationstation to use one supported resolution, and retroarch cores to use another. Automatic switching between resolutions on start and on end of games.

                Not an option per-se, but the runcommand launch menu allows you to choose from one of the supported resolutions - so RetroArch can run in a different resolution than the (default) one used by EmulationStation. Have you tried doing that ?

                  @mitu for some reason there are no resolution options in runcommand options. Pi5 through composite supports 8 resolutions, which are also available in retroarch and other platforms like Recalbox.
                  Can I add those supported resolutions to runcommand manually, so I can choose them?

                    This means they're not detected by runcommand. I guess that's one of the things that needs looked over for PI5 support.

                        Try to manually add an override for the resolution from RetroArch's menu and save it, see if it gets applied and overrides the resolution set by runcommand.

                          @mitu Thank you! Core overrides did work. :)

                            @Peeteris Glad it works. There may be a solution for the overscan margins being ignored - see https://github.com/raspberrypi/linux/pull/5845 - so check again when a new kernel shows up during regular updates with apt.

                              @mitu thank you very, very much for the help and information about kernel. :)
