Agree having the option to invoke Dark Room Mode at a user-defined time would be great. What if the user could set a time for the switch-over, and there was a notification box that pops up several minutes beforehand. (similar to the warning box you see if the computer is set to sleep at a certain time.) There could be an option to switch immediately, cancel, snooze, etc.
I think you are right. I think this wasn't flux, but a backup program I had running. I thought it was flux because it is the newest software on my machine. There must be an issue with an update to the backup software... Thanks for that other link too.
