Just discovered that I can manually change brightness by changing the integer value in:
/sys/class/backlight/intel_backlight/brightness -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1372143 Title: Asus X551MA-SX030D brightness and wifi fn hotkeys have no effect Status in “linux” package in Ubuntu: Confirmed Bug description: 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.
