Dim screen on Linux (Ubuntu 14.04)
On Windows you can dim the screen using Alt-PgUp and Alt-PgDn. The same keyboard shortcut doesn't work on Linux. This is my primary use for flux. How can this be done using Linux f.lux?
It might say in the f.lux menu, just like it does in Windows. Y'know what I'm referring to? The context menu. I hope that I'm conveying this clearly enough.
I do believe the Linux version is made from around 2010 and so it won't have the features from 2013.
It's rumored that there may be updates in the future.
Generally you can dim your screen on linux like this:
xrandr --output <YOUR-OUTPUT-DISPLAY> --brightness <NUMBER-BETWEEN-0.0-AND-1.0>
but I think flux uses the xrandr settings to change the temperature and it will set it back in a while when you try to change it. I use redshift instead of flux for this purpose, which allows changing the brightness.
