After the program installs, it will place a couple of icons in your menu. I am using Ubuntu MATE 18.04.3 LTS and the icons were placed in my Accessories menu.
Here's a closer view.
If you click on Brightness Controller it will bring up a Brigtness Controller dialog box that will control the brightness of a Primary monitor and/or Secondary monitor. This program will allow you to adjust your brightness to any level between 1% and 100%. You can also change the color temperature by changing the RGB values.
For advanced users, it has Primary Brightness, Secondary Brightness, and Color Temperature options. You will find a variety of preset settings under the Color Temperature drop-down menu.
The Brightness Controller will place a large icon in your system tray when it's active.
You can see the icon between my HP Device Manager icon and my Shutter screenshot icon.
You can control the brightness on your main screen by adjusting the brightness level or slider under Primary.
To exit Brightness Controller click on the program's icon in the system tray and click on Quit...
A Message dialog box will appear asking, "Are you sure to quit?" Click the Yes button if you do want to quit the program.
You can use the Brightness Controller Simple to the brightness of four different monitors. It doesn't have the Color Temperature (RGB) options and the huge icon in the system tray, but it's still an effective way of controlling the brightness of your screens.
You have a slider for each monitor connected to your system. I only have one monitor connected, so I have only on active slider.
