I am trying to get the Fn+F5 and Fn+F6 buttons to work on my ASUS UX305F
laptop running Ubuntu 14.04
. I have tried adding all of the following to /etc/default/grub
without success:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux"
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi="
I have even tried mixing and matching some of them. Each time I ran sudo update-grub
and restarted my computer only to be disappointed yet again. I also found that running acpi_listen
produced no output when I pressed the keys leading me to believe that they are not captured. How can I fix this issue?
EDIT:
acpi_listen
pressing F5:
^[[15~
acpi_listen
pressing Fn+F5:
No output
xev
pressing F5:
KeyPress event, serial 37, synthetic NO, window 0x5000001,

state 0x0, keycode 71 (keysym 0xffc2, F5), same_screen YES,

1What do you mean by
Fn+5
key? Do you mean you are pressingFn
key (which is alongside theAlt
orCtrl
key) and the5
numeric key? It will not send any special signal to your system. It will only send5
to your system.Fn
keys are hardware encoded. They don't work this way. – shivams – 2015-05-26T05:07:24.023@shivams: You might post your comment as an answer. This is not the first time that the question of mapping Fn has come up, and it's always the same answer. – harrymc – 2015-05-26T06:07:52.080
@harrymc Wonder why he has awarded a bounty for that. Anyways, I'll post an answer. – shivams – 2015-05-26T06:39:44.783
@shivams Please see edit – carloabelli – 2015-05-26T11:10:28.580
@cabellicar123 Okay i got that. – shivams – 2015-05-26T13:19:12.393
@cabellicar123 Open "Keyboard Shortcuts" in your Ubuntu and try assigning
Fn
+F5
to some action in that list. See if you are able to assign there. – shivams – 2015-05-26T19:18:22.883@shivams Tried it didn't recognize key press – carloabelli – 2015-05-26T19:27:42.620
@cabellicar123 Try using
xev
command also. – shivams – 2015-05-26T19:38:45.013@cabellicar123 Also, using the
xev
command oracpi_listen
tell me when you pressF5
andFn
+F5
, does it report detecting different codes or the same code. Moreover, when you pressFn
+F5
, does it even report anything inxev
? – shivams – 2015-05-26T19:39:30.257@shivams Please see edit. Both
acpi_listen
andxev
do record things for Fn + other function keys – carloabelli – 2015-05-26T22:16:56.717@cabellicar123 As per the output, it is clear that kernel is detecting it as different from
F5
. That is good. But why it is giving no output is strange. Anyways, did you try this :GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
– shivams – 2015-05-27T04:39:17.997@shivams That was the default it came with – carloabelli – 2015-05-27T15:07:48.660
@shivams In case you are still interested I submitted an official bug testing with the latest kernel here: https://bugs.launchpad.net/bugs/1458351
– carloabelli – 2015-06-01T14:32:29.443@cabellicar123 Oh. That's great. Let's see how they follow up on the bug report. By the way, we never asked your Asus laptop model number. Could you tell that (and include it in your question)? The problem so far appears to be related to your specific model. – shivams – 2015-06-01T15:41:58.383
I have the same problem. Did you find something? – Glats – 2017-04-20T02:14:14.347
