Ubuntu – software utility to adjust screen gamma/brightness/contrast


I use to work at night and it is eye-hurting to watch at lightbulb-bright screens (I've got two – laptop's built-in panel and an external 18-inch CRT) in a dark environment. So I adjust my screens to be darker.

Can I do this a software way instead of pressing monitors' buttons that many times every time?

I have been using this. It's very nice.

sudo apt install redshift

To use it just type in the terminal redshift.

gtk-redshift is just the GUI, not required.

f.lux is also an option (proprietary, closed source).
