I ran apt-get update and I also installed https://launchpad.net /~indicator-brightness/+archive/ubuntu/ppa and now the brightness slider is present in the applet and works. So I now have a workaround to easily change brightness.
the Fn brightness keys do not work and is confirmed from the fwts -i test that the ACPI hotkey is not being detected. The kernel was updated to the one mentioned in tags before fwts was run. for clarity: updated kernel: - no change fwts -i :- results above apt-update ; installed indicator brightness :- slider now present in applet and indicator brightness panel app works remaining issue: fn hotkeys not detected -- 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/1384435 Title: 8086:0416 [Asus N550JK] Backlight not adjusting either from Fn keys or from system settings Status in “linux” package in Ubuntu: Confirmed Bug description: system settings lock/brightness slider is absent. processed all the steps in https://wiki.ubuntu.com/Kernel/Debugging/Backlight and none of the workarounds work. /sys/class/backlight/intel_backlight/brightness echoing values to this DOES change the brightness though results.log says that _BCL is broken though ProblemType: Bug DistroRelease: Ubuntu 14.10 Package: linux-image-3.16.0-23-generic 3.16.0-23.30 ProcVersionSignature: Ubuntu 3.16.0-23.30-generic 3.16.4 Uname: Linux 3.16.0-23-generic x86_64 ApportVersion: 2.14.7-0ubuntu8 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: scott 2245 F.... pulseaudio /dev/snd/controlC0: scott 2245 F.... pulseaudio CurrentDesktop: Unity Date: Wed Oct 22 21:02:02 2014 HibernationDevice: RESUME=UUID=98c67a5a-4356-4e87-ac33-f59f8d45895a InstallationDate: Installed on 2014-10-21 (1 days ago) InstallationMedia: Ubuntu 14.10 "Utopic Unicorn" - Alpha amd64 (20140923) MachineType: ASUSTeK COMPUTER INC.
