Display brightness keys not registered by ~$acpi_listen

[Omadas]

Brightness keys donot repond, Brightness controls on xfce4_power_manager behave as expected. Either kernel is not recognizing the fn+f5/f6 commands or their is a problem with my configuration.

here is the event output of all of my fn+(f keys):
~ $ acpi_listen
button/volumeup VOLUP 00000080 00000000 K
button/volumedown VOLDN 00000080 00000000 K
button/mute MUTE 00000080 00000000 K
button/mute MUTE 00000080 00000000 K
 PNP0C14:00 000000ff 00000000
 PNP0C14:00 000000ff 00000000
 PNP0C14:00 000000ff 00000000
button/sleep SBTN 00000080 00000000
button/sleep PNP0C0E:00 00000080 00000001

(As a side note, my bios has no configuration options for the function keys.)

(On another note, it is worth noting the fn+f2 does not respond with an event calling for airplane mode either, which is not important to me but may be important for others, if this is fixed by any solution here I will make note, though airplane mode may be a feature request and not a bug.)

I have tried several options in the etc/default/grub file, these include:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash video.use_native_backlight=1"
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash video.use_native_backlight=0"
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=intel_backlight"
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi="
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux"

I am using Mint XFCE Sarah (Ubuntu Xenial) 64-bit, xfce4_power_manager was tested with all above configurations to both handle and not handle display brightness keys. My Computer is an ASUS model is X540LA. I am attaching a few files to help with this bug report.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.8 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.

I was unable to install the new kernel, the package is 'broken' and apt-get install -f just want to remove it. The kernel conflicts with ndiswrapper, and I need the internet for my job. Any suggestions on how to install the upstream kernel?

[Omadas (bsperger)]

Here is the make.log for ndiswrapper during failed kernel upgrade. Should I open a new bug?

[penalvch (penalvch)]

Omadas, please execute the following command only once, as it will automatically gather debugging information, in a terminal:
apport-collect 1618952

When reporting bugs in the future please use apport by using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs.

apport does not come installed with Mint... I installed it and sent it per your request.

Is there anything else I can do?
