After upgrading to last Kubuntu 13.10 release, I found Fn+Left works
correctly. Thanks. With kernels 3.11 and 3.12 also.

Title:
  [Dell Latitude D830] Fn+Left does not enable ambient light sensor

Status in “linux” package in Ubuntu:
  Fix Released

Bug description:
  According to Dell Latitude D830 manual, <Fn> and left-arrow key should
  activate the ambient light sensor, which controls brightness of the
  display based on light level in the current environment. I've checked
  it in WinPE and in GRUB - it works well. But in user account in my
  Kubuntu 13.04 <Fn> and left-arrow key returns:

  (XEV output)

  KeyPress event, serial 40, synthetic NO, window 0x4000001,
  root 0x103, subw 0x0, time 4948865, (162,-13), root:(164,45),
  state 0x0, keycode 201 (keysym 0x1008ffb1, XF86TouchpadOff), same_screen YES, XLookupString gives 0 bytes:
  XmbLookupString gives 0 bytes:
  XFilterEvent returns: False

  So, as we see, this is mistake and it should not return any code
  because it processes through BIOS and must switch on/of ambient light
  sensor to operate correctly according to laptop manual.
