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

brightnessdisplaysoftware-recommendationxorg

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?

Redshift

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).

In the ServerLayout section in your xorg.conf you should add something like this:

Section "ServerLayout"
    Option "Xinerama" "on"
    Option "Clone" "off"
EndSection

That should be enough to make sure xinerama works properly. If you don't have it already, you should add something like this aswell:

Section "ServerLayout"
    Screen 0 "first-screen"
    Screen 1 "second-screen" RightOf "first-screen"
EndSection
