Title:
  Some hotkeys don't work on Samsung R610

Status in “udev” package in Ubuntu:
  Expired

Bug description:
  Binary package hint: hal-info

  Hopefully I've done this correctly after following the hotkeys
  troubleshooting guide at
  https://wiki.ubuntu.com/Hotkeys/Troubleshooting

  A number of hotkeys on my Samsung R610 laptop do not work with Jaunty
  (they didn't work with Intrepid either). The keys that do not work
  are:

  fn+f2 Show battery gauge (Samsung specific feature)
  fn+f4 Switch between crt/lcd (haven't been able to test with external yet but the screen doesn't go black)
  fn+f5 Turn backlight on/off
  fn+f8 Easy speedup manager (Samsung specific feature)
  fn+f9 Wireless on/off
  fn+up Brightness up
  fn+down Brightness down

  I do not expect the Samsung features to work however I included them
  just in case something could be done with them. The easy speedup
  manager is supposed to toggle between low power mode, normal mode and
  high performance mode. The wireless and brightness buttons are most
  important for me.

  Please excuse the timestamps as I did the brightness keys earlier.
  Here is the system info:

  $ lshal | grep system.hardware
    system.hardware.primary_video.product = 1768  (0x6e8)  (int)
    system.hardware.primary_video.vendor = 4318  (0x10de)  (int)
    system.hardware.product = 'R610'  (string)
    system.hardware.serial = 'EY5793HQB00974'  (string)
    system.hardware.uuid = 'C0974B31-D21D-B211-8000-D9D1D18FB64A'  (string)
    system.hardware.vendor = 'SAMSUNG ELECTRONICS CO., LTD.'  (string)
    system.hardware.version = 'Not Applicable'  (string)

  It is an nVidia graphics card also if that matters.
