      That change looks good. You can probably save and restore the framebuffer width/height too although probably not needed in this case. We do this in runcommand as we allow changing of framebuffer resolution, and need to restore it correctly. We don't actually save the depth as above, so I will change that too.

      in the unlikely case that the framebuffer was in 8bit mode first, you would probably need to do fbset -depth 16; fbset -depth 8 (setting for to another depth to reset it). Although I don't think anyone runs in 8bit by default.

      Regarding 32 bit quality in emulators - I don't know - perhaps for some that run on the framebuffer - but there were some issues with 32bit in the past but I can't remember exactly what. I don't think this would affect retroarch/sdl2 etc.

        Also Kodi doesn't use the framebuffer but RPI dispmanx api etc so I wouldn't have thought you need to set framebuffer to 32bit mode for Kodi - for X applications though you would.

          @Rascas While on the subject of framebuffer depth - looks like 32 is the best choice now anyway - https://github.com/raspberrypi/firmware/issues/685

            @Rascas any news on this ? More black screen reports have come in. If you are short on time, I might add a fbset workaround to the end of the Kodi launch or ES launch script via RetroPie-Setup.

              @Rascas also just FYI, framebuffer depth is now 32bit by default. https://github.com/raspberrypi/firmware/issues/685

                @BuZz yes, I am a bit short on time, I will change kodi launch script when Kodi 17 comes out (it should be this month still) but change it where you see more fit if you want till there.

                  Hi I have a very similar issue however I'm not using Kodi. For me it seems like the display sleeps but only for the RP scripts and other shell options. Emulationstation displays ok however if I enter a script the screen is blank. Also when I launch a game I dont see the press any key to configure menu either. When I connect a keyboard and press a key it appears again. The controllers I use dont wake it however. What is causing this and how do I change it please?

                        @Morphy I missed that - start a new topic after reading https://retropie.org.uk/forum/topic/3/read-this-first and I will advise.

                        I have no details about your set-up.

                          @BuZz sorry for the necro, is there a problem if we change this for Kodi 18, to instead of just saving the bitdepth, to save everything (including the resolution) and restore it back at exit ? That would be usefull for us to save some memory from the framebuffer when Kodi is running, since this new version can consume more than the default 256MB. You have the current Kodi 18 start script here if you need more info:

                          Thanks

                            @Rascas May be my memory but I thought we already saved everything ?

                              @BuZz Ah yes, you are right, I was confusing 2 different fixes ... Anyway, there are some improvements that we can do for Kodi 18, when it approaches the final/stable version I will talk to you.
