--- Comment #20 from Aaron Wolf <wolft...@gmail.com> --- I don't know when it changed, but the brightness of external displays is now working perfectly! The system tray brightness/night-light tool has scroll-wheel motion to change brightness, and it's superb! This is happening in software, independent of the display hardware settings. So, it's clearly much more trivial now to finish this request here. The very same control that now exists manually just needs to be added to the night-light settings. Just have an option to choose to automatically reduce the display brightness at the same time as the red-filter as part of the night-light settings! -- You are receiving this mail because: You are watching all bug changes.
