Manually adjusting brightness no longer workers after 8/5/20 Windows update?
For a while now, I've used f.lux's keyboard shortcut of alt+pagedown to reduce my monitor's brightness at night (on top of the usual color settings). However, after the most recent windows update yesterday, this functionality no longer works - I get the f.lux popup of:
dimming until sunrise
Circadian response: 0% (Circadian darkness)
but unlike before, my monitors don't reduce in brightness at all.
Is there a way to fix this?
uninstalling and re-installing f.lux worked
The problem comes back for me when I restart the computer
