My Toshiba C800 laptop (12.04 LTS desktop) has special function keys as follows:

fn + :

  • F2 -> BRIGHTNESS DOWN
  • F3 -> BRIGHTNESS UP
  • F4 -> DISPLAY SELECT
  • F5 -> TOUCH PAD on/off
  • F6 -> PREVIOUS
  • F7 -> PLAY/PAUSE
  • F8 -> NEXT
  • F9 -> VOLUME DOWN
  • F10 -> VOLUME UP
  • F11 -> MUTE
  • F12 -> WiFi on/off

F6 to F11 (media player keys) work correctly, but the keys from F2 to F5 and F12 are not working.

Why would some function keys work, but not others? What can be done to fix this?

  • some of these can be set under keyboard shorcuts, have you tried any boot parameters? like acpi_osi=Linux or acpi_osi=Windows – GM-Script-Writer-62850 Jul 06 '13 at 01:58

Have you tried the package fnfxd? Supposed to enable access to the function keys in Toshiba laptops, though have not tried this personally. You may also wish to check for fnfx-client in Launchpad. Have not personally tried as my laptop is pre-built for Ubuntu by a company that only builds Ubuntu laptops, so the hardware just works. However, still do my own builds and deployment methods.
