Ubuntu 21.04 set brightness

There is no brightness button in Ubuntu 20.04. Why? But you can set the brightness via terminal commands.

Step one: find the name of your monitor.

In my case:

# xrandr | grep " connected" | cut -f1 -d " "
# HDMI-2

Then set the brightness in the terminal:

# xrandr --output HDMI-2 --brightness 1

Night settings could be a brightness of e.g. .75

No GUI for the screen settings, such as color and brightness etc. is yet another serious UX-flaw in the problematic Ubuntu 20.04. This update is not the best we saw from Ubuntu. We need UX'ers in Ubuntu.
