Pilot6, could you please test the latest upstream kernel available from the very top line at the top of the page (the release names are irrelevant for testing, and please do not test the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue.

If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested exactly shown as:
kernel-fixed-upstream-3.18

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.

Plot6, just to clarify, are you the original reporter (Dmitry Tunin) of https://bugzilla.kernel.org/show_bug.cgi?id=89401 ?

Yes, I am the original reporter. The problem is a bit complex.

My "acpi_osi=" solution used to work, until Aaron made that DOD commit.
Now the brightness keys do not create events at all in 3.18 kernel.

He needs to fix that first. Regarding Ubuntu kernel, the patch works.

You can see commits in my tiny fork.

@Christopher

And also it would be helpful for everyone if that commit

https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/acpi/video.c?id=0b8db271f1592e118feef7300f6da85bea9366da

is not backported to Ubuntu, until the issue is fixed. Because now there is a workaround with "acpi_osi=" boot parameter for some Asus models, but after that it is competely blocked.
