After installing Ubuntu 20.04 I get the brightness option as in normal Ubuntu it should be, but I have a problem that when I start Ubuntu it used to stuck on the starting screen so for that I run sudo gedit /etc/default/grub and then change
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset".

After that I am getting no brightness option, nowhere, neither in setting, nowhere. I have tried this answer but it didn't work. And I am not able to work on my laptop, the brightness is a painful thing now. So am I the only here with this?

In the meantime, to adjust the brightness from the terminal, use

~$ xbacklight = 75 

where 75 is the percentage.
