      hi, I am a long time user of f.lux and decided to register in this forum.
      what I have found is that on fast startup enabled it is broken (dimming function). But you can simply fix this by signing out (user) and signing in again. No need to restart fully

        Hi,

        I use a laptop with 2 identical external displays. Ever since the 1903 Win10 update, my primary external monitor has been working fine with f.lux for dimming. My laptop display also has been working fine. However, my other external display does not respond to f.lux dimming.

        I tried to disable fast boot, but that did not fix the problem. I am on beta version 4.105.

        I have attached my driver info:

          @rajivvarma I would definitely look for a newer DisplayLink driver and possibly enable the gamma ramp registry feature.

            @locarno tell me exactly what you mean by "turn off and turn on"? like a full system reboot?

            @rutra80 already explained this.

            @rutra80 said in Windows 10 May update (1903):

            Ok so today problems came back and I think I know when - after full system restart everything is ok, but then when you have Fast Startup power option enabled and you shutdown and startup the system, things are borked again. So, it seems like something is wrong with kernel modules being woken up after hibernation, which is what happens when one has Fast Startup power option enabled (which is a default system setting) - only user mode and services get shutdown but the kernel gets hibernated.

                What is fallback mode in f.lux ?

                I have f.lux 4.104. It is good version ?

                When Microsoft fix kernel or something ? They even know about this problem ?

                  MS seems to be working on it, yes.

                  f.lux uses the GPU in fallback mode, which is why screenshots are tinted. This code path was in there for DisplayLink monitors and it worked automatically for this Windows bug.

                    @herf Seems like my USB3.0 -> HDMI adapter might be the cause of my Win10 problems. I'm gonna try some different adapters from work and see if they make a difference. I also updated to the latest DisplayLink drivers, thanks for the recommendation.

                        As a followup, the following made my DisplayLink external monitor work with f.lux again:

                        (1) Upgrade the DisplayLink drivers to the latest stable.
                        --> https://www.displaylink.com/downloads/windows

                        (2) Set enableGammaRamp to true using regedit.

                                  @gigel thanks - it looks like your video driver may be older.

                                  Some OEMs hold back the drivers which has been OK in the past, but recently there has been so much going on with Windows color that it is better to update. There are 2019 drivers here for the HD 530:

                                      Brand new pc, never had this issue on my win 7 machine. All my drivers appear to be up-to-date "the driver youre using is the newest available". Shame cause ive been sleeping terribly now. It works after a reboot until the pc goes to sleep and ive turned off fast startup (use and SSD) and usually leave on for a week at a time. so now im rebooting every day before supper when the sun goes down.
                                      i test by manually changing the monitor colour via flux to candle light.

                                      really hoping this gets fixed by f.lux because MS wont fix anything.

                                        @highwayrob We think the "fast startup" bug is fixed now (this is Windows update, not drivers). If you are having trouble, please post f.lux options > driver info in this thread (using the latest build of f.lux).

                                          thanks for the speedy reply, here's requested info

                                          I think ill leave fast startup turned off anyways, as i leave pc running for a week preferably.( i realize windows caused the issue, but if a workaround cannot be found from flux, i mean then windows wont ever fix their bugs- rarely)
