That's a kernel regression,  I'm afraid. They all map to the same scan
code now, so userspace cannot tell them apart any more.

** Package changed: systemd (Ubuntu) => linux (Ubuntu)

Title:
  Wrong keymap on HP Compaq 8710W

Status in linux package in Ubuntu:
  New

Bug description:
  On my HP 8710W, before the latest round of updates, the fn+f9, fn+f10,
  and fn+f11 would control brightness up, brightness down, and ambient
  light sensor toggle, respectively. Now, according to evtest, all three
  are mapped to KEY_FN_ESC (fn+esc).
