I use f.lux to dim the brightness on my laptop screen. And Alt + Page Down to dim the display. But it resets everytime I start my laptop.
Is there any way to save the brightness setting in f.lux?

We don't currently have a way to save this setting since the combination of backlight dimming + software dimming can make your computer pretty dark during daytime (so dark you probably couldn't use your computer), so we make you dim by hand for now.
We'll think about some ways to be smarter about this and maybe restore it in the cases where it makes sense (when you're less likely to be in a bright room, for instance.)
