Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that your bug report is not filed about a specific source package though, rather it is just filed against Ubuntu in general. It is important that bug reports be filed about source packages so that people interested in the package can find the bugs about it. You can find some hints about determining what package your bug might be about at https://wiki.ubuntu.com/Bugs/FindRightPackage. You might also ask for help in the #ubuntu-bugs irc channel on Freenode.

To change the source package that this bug is filed about visit https://bugs.launchpad.net/ubuntu/+bug/1589886/+editstatus and add the package name in the text box next to the word Package.

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.7-rc1 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[Cruz Fernandez (cruz-fernandez)]

I could test the kernel v4.7-rc3-yakkety. In that one the hotkeys is fixed!!!! Thanks a lot @jsalisbury

[Alex Hung (alexhung)]

New kernel includes a new driver intel-hid that handles wireless hotkey; however this is not yet available in xenial kernel.

[Alex Hung (alexhung)]

Yakkety may ship with kernel 4.6 or later, and intel-hid will be included without the need of backport.

[Kamal Mostafa (kamalmostafa)]

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-xenial' to 'verification-done-xenial'.

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!

[Cruz Fernandez (cruz-fernandez)]

Pressing wireless hotkey (Fn + PrtScr) with kernel 4.4.0-29-generic (the proposed kernel) now works! (turns on and off Bluetooth and WiFi)

In dmesg I've seen the old warning still (between some lines for starting-up and down the network and bluetooth),
[ +0,034110] dell_wmi: Unknown key 153 pressed

I suppose that's just a 'nitpick'.

I'm not sure if @kamalmostafa intended me to change the tag from 'verification-needed-xenial' to 'verification-done-xenial' though.

[Alex Hung (alexhung)]

I also verified it on another XPS 13 with the same problem and kernel 4.4.0-29-generic fixed it.

@Cruz,

I sent the backport patches and I will change the tag. Thanks for reporting the bug and helping test the proposed kernel.

[Cruz Fernandez (cruz-fernandez)]

Way to go @Alex Hung !!!
