[HP 242 G2] Wireless key events were not detected at all

[Po-Hsu Lin]

CID: 201309-14199 HP 242 G2

The wireless key press / release events were not detected at all.

Steps:
1. Install 12.04.4 + update (3.11.0-19), boot to desktop
2. Try to control the wireless by pressing the wireless hotkey

Expected result:
* Wireless functionality could be controlled by the wireless hotkey

Actual result:
* Wireless hotkey was not working at all, nothing captured by "xev" or "sudo showkey -k"

Verified with the dailylive mainline kernel (2014 Apr.7)
Linux 201309-14199 3.14.0-999-generic #201404070205 SMP Mon Apr 7 06:06:25 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

The hotkey works with it. (Also the wifi LED)

[Edward Lin (airken)]

Duplicate issue, same as bug 1118689

The patch is available in kernel 3.14

    hp-wireless: new driver for hp wireless button for Windows 8

[Edward Lin (airken)]

Alex will submit the patch to SRU.

[Alex Hung (alexhung)]

Verified #3 with saucy (3.11.0-22) and trusty (3.13.0-27) kernels, and F12 hotkey is able to toggle wireless states.

[Joseph Salisbury (jsalisbury)]

I believe this bug will be fixed by commit 15d75fcebdf78d316a980487eddcac8e4f1574c8, which is in Trusty as of Ubuntu-3.13.0-28.51. This commit is a cherry pick of upstream 54290fa6.

Can you test the 3.13.0-28.51 kernel and confirm if it fixes this bug or not? It can be downloaded from:
https://launchpad.net/~canonical-kernel-team/+archive/ppa/+files/linux-image-3.13.0-28-generic_3.13.0-28.51_amd64.deb

[Joseph Salisbury (jsalisbury)]

Also, un-marking this as a duplicate of bug 1118689 since the kernel commit references this bug in the BugLink.

[Edward Lin (airken)]

I test the kernel image - "linux-image-3.13.0-28-generic_3.13.0-28.51_amd64.deb".
I can't find hp-wireless.ko after installation.

So I install linux-image-3.13.0-28-generic_3.13.0-28.51~precise1_amd64.deb.
The wireless key works fine on this image.

And, as Alex mentioned in bug 1118689 #6, BIOS no longer uses WMI to control the wireless if win8 capability is enabled.
The patch I mentioned #3 (upstream 54290fa6) fixed this bug.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-trusty' to 'verification-done-trusty'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
