I think this is a fantastic idea. I would use this for many reasons.

your problem is not to do with f.lux , its becaise bad display port cable, try buying a new one.
I had same problem and solved buying a good dp cable.

cheers

Can you post the version of macOS and the version of f.lux?

I have a similar issue. I'm running High Sierra on a MacBook Pro with an external monitor connected via thunderbolt. Whenever the screen goes into sleep mode, it's really crashed. the screens are black, but not completely off. I have to do a hard restart. Took a lot of trial and error, but it stopped happening once I disabled Flux.

@Naomi-Schoenfeld oh yes!

There is an Option to use "expanded daytime settings" and that will unlock the slider for daytime and sunset.

People usually try out the lowest and highest value in a slider, so we limited them, but if you turn off bedtime mode, you'll probably want to set this option.

@herf Changing color profiles and rebooting fix this problem. thank you!

I spoke too soon. Still crashing :(

When you move the slider all the way to the right, it turns off this part of the schedule. We did this for people who really like sunrise to sunset only.

All you have to do to fix it is to choose any other slider point in bedtime mode (or pick a preset other than "Classic f.lux")

This is a macOS feature, and we just turn it on.
Newer apps will switch.

No, I also can't see that.

@herf said in Removing app from Disable for...:

@THX1138b this is our macOS forum, so it is different. For Windows, I recommend you get the latest f.lux v4 which has a complete list of disabled apps in the menu: https://justgetflux.com/flux-setup4.exe

Thanks but I have version 4.47 and I have explored every menu and there is no list of disabled apps.

There is "dim on disable" which may help...
