danieru, thank you for reporting this and helping make Ubuntu better. Could you
please test the latest upstream kernel available from the very top line at the
top of the page (not the daily folder) following
https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional
upstream developers to examine 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-3.17-rc6
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.

** Summary changed:

+ [Asus X551MA] Brightness+fn hotkeys have no effect
** Description changed:
Just installed Ubuntu 14.04.1, have run the latest updates and the
- brightness and wifi fn hotkeys don't work.
-
- Here's a complete list of working/non working fn hotkeys:
-
- fn + f1 (suspend) yes
- fn + f2 (wifi) no
- fn + f5 (decrease brightness) no
- fn + f6 (increase brightness) no
- fn + f7 (turn off screen) yes
- fn + f8 (change screen output) untested
- fn + f9 (disable/enable trackpad) yes
- fn + 10 (mute) yes
- fn + f11 (decrease volume) yes
- fn + f12 (increase volume) yes
-
- I had started this bug report from ubuntu-bug, so it *should* have
- attached a plethora of hardware info, but if there's any other
- information I can provide to help with this, just let me know.
-
- Also, I think this is a kernel issue, thus I put 'linux' for package,
- but if I'm mistaken, please feel free to change it.
