MacBook Air 6,1 and 6,2 (mid 2013) backlight driver
You need to have the kernel headers (e.g. linux-header-generic) installed for the kernel you're compiling for. You also need the build tools (build-essential or similar).
Note: You no longer need to specify mba6x_bl as your backlight device in /etc/X11/xorg.conf. This is now handled automatically by promoting the driver above the ACPI backlight interface.
At this point you can load the module
sudo modprobe mba6x_bl
Then restart X (usually log in / log out will do the trick). The module should automatically load on next boot on any MacBook Air 6,x.
You may need to follow the directions suggested in #65 and do the following: 1. Create

Section "Device" Identifier "Intel Graphics" Driver "Intel" Option "Backlight" "mba6x_backlight" EndSection3. Remove
/usr/share/X11/xorg.conf.d/20-intel.confor move it to a backup directory. 4. Log in/log out or
You can either follow the long route https://wiki.kubuntu.org/Kernel/Dev/DKMSPackaging, or download a pre-made .deb.zip file of v1.1.0 from https://github.com/patjak/mba6x_bl/files/505288/mba6xbl-dkms_1.1.0_all.deb.zip, which can be installed with
dpkg -i. (Installing v1.0.0 can result in build errors; see #55.)
