Title:
  Unable to change screen brightness in ubuntu desktop

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I have Dell G15 5515 Ryzen edition. It has Nvidia 3050 graphics.

  In /sys/class/backlight directory, there are two directories
  amdgpu_bl0 and nvidia_wmi_ec_backlight.

  When I change the screen brightness via slider then it changes the
  brightness value of nvidia_wmi_ec_backlight but it doesn't work. When
  I manually changed the value of amdgpu_bl0 brightness file then my
  screen brightness changed.

  My BIOS is updated to the latest version and I have NVIDIA Driver with 
version 510.73.05.
