I have lowered the brightness of my screen to the maximum, there is a tool or software to lower the brightness of the linux system even more, I use Linux Ubuntu
I've added this command. But what happens is that I get the brightness at the system level, the one that comes by default doesn't leave me even more.GitHub - Hummer12007/brightnessctl: A program to read and control device brightness

It doesn't work for me, I don't know why I have done all the steps@edyuser12345 , you could try this - I have just installed it on my Ubuntu just now and it works fine.

The xcalib program, if you are running X, will control brightness and contrast and gamma. For example, the following lowers brightness on my screen:I have lowered the brightness of my screen to the maximum, there is a tool or software to lower the brightness of the linux system even more, I use Linux Ubuntu
xcalib -a -co 70

Run: xcalib -c, to clear it. There's lots to experiment with the program and I expect that different commands will suit different monitors.Code:xcalib -a -co 70
If you have really reached the maximum low (also called minimum)... then that's probably all you're going to get from software brightness controls.On my computer system I have the brightness at maximum low but I want to set the brightness lower

This warning is most likely do to the use of Wayland instead of Xorg - you could try disabling WaylandWarning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway
@atanere :-But you might also look at Redshift to see if it may help with your eye strain. It is a software method of controlling the blue light... not a brightness control.
