Hi Jaap - what files are you seeing? Usually if you aren't using the interface it should be pretty quiet.

Our "disable per app" feature might read from disk to understand the names of an app.

+1 on automatic brightness. I use both screens (laptop + 32" 4K display on external GPU) at maximum brightness during the day and minimum brightness during the evening. I am really tired of adjusting it every evening and morning. External monitor also gives an extra difficulty, as it does not listen to any hotkeys.
So to solve this simple issue I currently have another app installed - Monitorian (from MS store). It kind of solves the issue, but requires too much of my attention (is finnicky when plugging the external GPU in and out).
So it would be great to add this feature to f.lux, THEN it would be the ultimate solution.

Well this is kinda frustrating that the full screen is not working. I found a post here which fix full screen not working error. You can check that post for help.

* how I can get rid of it

Yes, please! I agree with this. I use Excel a lot (main reason I need f.lux) and alt+PgUp is the shortcut to scroll across spreadsheets.

So I have to click in f.lux, click Options and Smart Lighting, check the Hotkeys to On, adjust the brightness, then check Hotkeys to off. It's too many clicks!

Either the option of changing a Hotkey or a simple brightness slider would be brilliant. Thank you!

The problem comes back for me when I restart the computer

I think I have a similar problem, double click on the curve under the slider to run a 24h preview, after that it activates for me.

(double click anywhere in the red square)

there is a "disable by monitor" feature in the disable menu.

Same here

Is this forum dead? I posted here before and no one replied then either.

Strange, now it turns out to be the normal "/noshow" string.
Solved.
