Recently my graphics driver was updated to NVIDIA 460.32.03 on Ubuntu 20.04. Since the update, I can’t change the brightness using either my lenovo laptop’s function key or the brightness adjustment bar from system settings. Although, I am able to change the brightness using “xrandr” command. Also, the Nvidia 450 driver works fine. My kernel version is 5.8.0-36-generic.

I tried the fix [here](https://forums.developer.nvidia.com/t/problem-driver-nvidia-455-45-01-on-linux-mint-20-4-6-7/165402) and it worked for me.
