[Bug 1347835] Re: Hot Keys not working (not registered in evtest or acpi_listen)

  Thread Previous • Date Previous • • Thread Next 
I vaguely remember this working in 12.04, however not having had to use
this functionality until yesterday, since January I can't say which
update possibly broke the functionality. I have just installed
3.16.0-031600rc6-generic and the problem still exists with no
registration in evtest or acpi_listen.

** Tags added: kernel-bug-exists-upstream

** Description changed:

  I'm using a Fujitsu UH552 laptop with Ubuntu Gnome 14.04. Effectively my
  FN+(F key) special keys sort of work. My mute (FN + F3), brightness down
  (FN + F6), brightness up (FN + F7), volume down (FN + F8), volume up
  (FN+ F9) work. However the following issues exist :- The radio kill (FN
  + F5), and the external monitor display selector / choose between
  duplicate, extend or external only button (FN + F10) does not work. The
  print Screen (FN + Insert) works, but its functionality is duplicated on
  FN + Delete.
  
  I have checked whether I am using the fujitsu_laptop module (which I am)
  using lsmod | grep fujitsu.
  
  I have run sudo evtest and only the keys that are working / duplicated
  are detected, however the duplicated key has the same scan codes (4 and
  99). I then ran acpi_listen and the only hot keys recognised are:-
  
  button/mute MUTE 00000080 00000000 K
  video/brightnessdown BRTDN 00000087 00000000
  video/brightnessup BRTUP 00000086 00000000
  button/volumedown VOLDN 00000080 00000000 K
  button/volumeup VOLUP 00000080 00000000 K
  
  Help kindly appreciated.
