Brightness control can be achieved with the GNOME shell extension Adjust Brightness Icon as a work around. It places a clickable icon on the top bar which cycles through a number of brightness options.
Install GNOME extensions if you have not already done so and select the extension. This will place an icon on the top bar which allows you to cycle through different settings of brightness.
If you don't have GNOME extensions installed this guide provides a handy reference.

Does this work to control brightness with hotkeys? – vanadium Apr 05 '20 at 11:11

@vanadium its a work around and I have amended my answer to reflect that. Thanks. – graham Apr 05 '20 at 11:16

I can control brightness threw the slide bar. But i can't do it with fn + f11 and fn + f12. That is brightness up and down. – Muhammadali Nazarov Apr 07 '20 at 17:31

I don't know why, but when I tried to do it with hotkeys today, it worked! I was surprised and restarted notebook, then it stopped working and I even surprised more. I don't know why it started and stopped working. – Muhammadali Nazarov Apr 07 '20 at 17:32

I found out the answer. When I suspend the notebook and turn it on, the hotkeys work. Idk why. – Muhammadali Nazarov Apr 07 '20 at 18:06
