It would be nice to fix before Fedora 22 release. If more info is needed, I will be ready to provide them.
Comment 6 Fedora Blocker Bugs Application 2015-04-10 17:33:36 UTC 
Proposed as a Blocker for 22-final by Fedora user luya using the blocker tracking app because:

 ASUS wmi Hotkeys is correctly detected and activated but user is unable to use hotkeys (via "Fn"). Output fail to work as the xev output shows nothing. Test done on newer ASUS laptop, in this case X500ZE.
Comment 7 Josh Boyer 2015-04-10 17:35:24 UTC 
It would be nice, but I really don't think this is blocker criteria.  Fn keys fail to work on one laptop or another with essentially every upstream kernel release.  I don't think this model is special.
Comment 8 Luya Tshimbalanga 2015-04-10 18:08:01 UTC 
is it for every newer model Fn keys fail to work? For what I understand, there should be a generic Fn keys input allowing decent functionality for those laptop series.
Comment 9 Petr Schindler 2015-04-20 17:51:26 UTC 
Discussed at today's blocker review meeting [1].

This bug was rejected as Final Blocker - this is hardware-specific (model or manufacturer) and in non-blocking functionality in any case

Comment 11 Luya Tshimbalanga 2015-06-05 17:22:40 UTC 
Latest update on F22 kernel returns same result. Basically the device was detected and correctly set up but inability to use Fn key. Note the laptop runs on EFI mode which was the default.

Xorg,log on 20150802

Include the latest log. Setting secure boot off has no effect on the input following one suggestion. The Asus WMI is running fine but no Fn shortcut input.

Reading the source code of asus-nb-wmi:
http://lxr.free-electrons.com/source/drivers/platform/x86/asus-nb-wmi.c

It looks like wapf value is unassigned to my current laptop (X550ZE) which probably explain why Fn keys does not work. According to the code, the wapf value should be set to "0" because the laptop have both Bluetooth and Wifi.
Comment 16 Luya Tshimbalanga 2015-10-16 17:26:27 UTC 
Bumped to rawhide as the Fn key fails to work.
Comment 17 Luya Tshimbalanga 2015-11-04 04:07:28 UTC 
Update after running Fedora 23. Fn only works with the following hotkeys:
Pgup, Pgdn, End, Home

Other hotkeys for media, backlight, suspend failed to work. Perhaps having some help from ASUS themselves will be handy. I have contacted the author for that module asus-wmi which is himself unable to reach out ASUS. It will be nice kernel developers contact them to fix that quirk.
Comment 18 Luya Tshimbalanga 2016-08-31 00:34:49 UTC 
Working with upstream revealed the bug related to ACPI due to a change the BIOS scheme found inside ASUS laptop i.e X550Z in my case. Once that cause figured out, all functionality from keybord to lid is nearly restored. See explanation on 
https://bugzilla.kernel.org/show_bug.cgi?id=115021#c54

I will leave this bug open until the fix is fully implemented upstream.
Comment 19 Luya Tshimbalanga 2016-08-31 01:46:56 UTC 
*** Bug 1338082 has been marked as a duplicate of this bug. ***
Comment 20 Luya Tshimbalanga 2016-09-17 09:30:52 UTC 
Current status of fix upstream:
https://patchwork.kernel.org/patch/9318649/

It looks like it will land on next kernel 4.8.0rcx, I will test the next release when available.
Comment 21 Luya Tshimbalanga 2016-11-08 02:35:21 UTC 
The fix landed in the upstream kernel 4.9:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=2a5708409e4e05446eb1a89ecb48641d6fd5d5a9

I am closing this report as Rawhide will get fix accessible via building system
