        I just saw this: http://jonls.dk/redshift/

        I don't know if it would be of any use...

          It doesn't support Mir/Wayland, and Mir/Wayland don't allow arbitrary apps access to the screen like that, so no, it's not really.

          This is something that really needs to get baked into the system.

            I'd see a blue light filter function as a very high priority given how it's known to affect peoples sleep so badly.

            How can you trust that an app really won't send some company your location data, when you tell it not to? The only way you can trust a program not to do something it isn't supposed to do is if it is free software. ~ RMS

              Everyone is entitled to decide their own priorities. If this is "a very high priority" for you, the joy of open source is that you can do something about it. Here's a plan:

              1. Check out the Mir code and get it building.
              2. Find the mir_demo_server example and add a "blue light filtering" option by setting gamma ramp on the display configuration.
              3. Try it out and confirm if it has the desired results.
              4. Adapt this code to provide this "filtering" option via the MirAL interface.
              5. Propose (and get accepted) this addition to the Mir project.
              6. Check out the QtMir code and get it building.
              7. Make use of the new MirAL option for "blue light filtering".
              8. Propose (and get accepted) this addition to the QtMir project.

              There are people willing to help with every step along the way.

              Good luck!

                Hi Alan. But blue light affects everyone's sleep. Sorry, but I don't think I want to go through all of that. :see-no-evil_monkey:

                  @Opolork if it isn't a priority for you, that's fine too. 😉

                    @alan_g Are there some suggested links to the Mir code etc?

                    Anyone know where to find these parts in the code?
                    Thanks

                      There was an email address at the bottom of the Redshift website, so I just pinged the developer and asked if he might consider contributing some expertise to Mir.

                        For starters, there's a handy guide to step 1 here: https://mir-server.io/doc/getting_involved_in_mir.html

                          As dobey said above, there's very little overlap. About the only thing in common is the choice of values for the gamma curves.

                              A workaround for now. I will not use the smartphone after 8:30pm to combat that pesky nighttime blue light. 💡 🙂

                                @Opolork in the meantime there's a proper solution, you could use a blue light filter screen protector on your device, or even use glasses with that kind of filter 😉

                                  Those are also valid workarounds. Although I think it's good to ditch the smartphone around 8:30pm anyway - to wind down for the night. I go to bed at 10:45pm. 🙂

                                    @Opolork wrong answer! You need to keep testing and improving UT until 4 a.m. at least 😆

                                      I've added an issue to the Mir project. (But it won't be scheduled in the foreseeable future.)

                                        Far too late for an extreme early bird like me. 😉 🐦
