Title:
  OLED brightness control on Intel Iris Plus Graphics G7

Status in xorg package in Ubuntu:
  New

Bug description:
  Hi

  I'm testing kubuntu 20.4 with my HP spectre x360 13 aw0720nz.
  The hotkeys to adjust the OLED brightness do not work.

  Adjusting the display brightness editing the file brightness in
  /sys/class/backlight/intel_backlight doesn't work either. At
  /etc/default/grub I already added "acpi_backlight=vendor"

  I found an article, that fits to the topic:
