Brightness control hotkeys not working!
-
Usually these keys don't work when you haven't done the "expand range" system change.
Look in the "Lighting at Night" menu and choose "Expand range" and see if that helps?
We have heard that on upgrading to Windows 10 this gets broken, and you have to uninstall/reinstall to make it work.
-
Keep in mind that f.lux's brightness control isn't adjusting the monitor's backlight brightness; it's just adjusting the black level. If you want a true brightness adjustment, then you will need to adjust the brightness of your monitor's backlight - usually with your monitor's onboard controls.

@herf and twocables, It was working before I expanded the range, and it stopped working randomly after I clicked on the expand range option (but I hadn't rebooted so it could take effect at that point. After I rebooted I had the expanded range available but the hotkeys still Didn't work.
I'm on Windows 7. My monitor is already on it's lowest brightness setting and it's way too bright, which is why I was using dimscreen, but I wanted something I can install so I don't have to manually start it up each time (dimscreen is portable) and I thought flux was the answer until the hotkeys stopped working.

Whoa. It's too bright even at the lowest brightness setting? Are you using your computer in total darkness? I hope not because that's bad for our eyes to do that, even with the monitor at the dimmest setting.

Here's me with the stupid question again, is there any chance that the hotkeys option got disabled somehow?
-
@lorna Right there is a menu in "Extras" that disables the hotkeys.
Does f.lux "try" to make the screen dim and fail, or does it just not work at all? -
Well he did say "I still have the hotkeys enabled under extras".
-
@TwoCables oh yes.. look at that. facepalm.jpg
-
yup hotkeys definitely enabed lol.
Flux doesn't dim the screen at all. (I don't get any type of message, literally nothing happens, whereas it used to work when I 1st installed it)
-
Is there any chance another app would register the same keys after f.lux?
Does restarting f.lux help?

It's mysteriously working again, I didn't install/uninstall anything. How strange! At least it's working again, but out of interest how do you restart flux?
If you mean uninstall and reinstall I never tried that so it could have possibly helped, if you mean re-booting the system (or shut down) it didn't fix the problem.

Right-click the icon, choose 'Exit f.lux', and then open f.lux again.
(when in doubt, right-click the thing you're curious about)

It could be possible that one app is accepting hotkeys while it's running, and our global one is still running when it's not active.
Avoiding all hotkeys other apps use is very hard. :)

Sorry to necro, but in case anyone else has the same problem as OP, because I have a fix--
What is your keyboard layout? Are you using a non-English keyboard? I occasionally have the same problem while using a custom keyboard layout (which I designed in MSKLC to work for multiple languages). I don't believe I've had issues while using a US English or German keyboard, but I haven't been keeping track up to now and I switch often.
After I switch to another layout and switch back to my custom keyboard it works again, so I'm not sure exactly what the issue could be. Just something to try if the hotkeys stop working!
-
Sorry to necro again, but i realzied theres a really simple solution to this problem. Make sure you don't have numlock on... i feel really stupid after downloading 3 other screen dimmers

Why aren't you using the Page Up and Page Down keys that are above the Arrow Keys instead? So above the arrow keys there's Insert, Delete, Home, End, Page Up, Page Down.
