Comment 14 for bug 527157

I made the modification to apply to gnome-power-manager-2.32.0 tarball in Maverick.

Please, test it.

For me it solve everything with brightness

 * Adding /apps/gnome-power-manager/backlight/brightness_in_hardware key.
  It is just workaround to prevent g-p-m from adjusting brightness,
  if Fn + Brightness Key was pressed. It must fixed:
  LP: #527157 - Skipping levels in case of Fn + Brightness Key
  LP: #415023 - Flushing or flickering on MSI WIND U100 with not-updated Bios (all clones too)
  LP: #261635 - Fn + Brightness keys could be added to /lib/udev/rules.d/95-keymap.rules
  to make them known.
