Title:
  Adjusting brightness with hot keys doesn't work properly on Asus
  K55VD-SX205R

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  Full computer model: ASUS K55VD-SX205R

  What you expected to happen:
  When you push Fn+F5 brightness of screen of Asus K55VD notebook decreases.
  When you push Fn+F6 brightness of screen of Asus K55VD notebook increases.

  What happened instead:
  Hot keys that adjust brightness (Fn+F5, Fn+F6) don't work. Brightness stays the same.

  WORKAROUND: 1. sudo gedit /etc/default/grub
  2. find the line starting with GRUB_CMDLINE_LINUX_DEFAULT
  3. add "acpi_osi=" to the options
  4. sudo update-grub2
  5. reboot
