Hi,

Success :)

Any idea when this will be accepted upstream ? (kernel version ?)

find /sys -name brightness
/sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-eDP-1/intel_backlight/brightness
/sys/devices/platform/applesmc.768/leds/smc::kbd_backlight/brightness

cat /proc/cmdline 
\boot\vmlinuz-4.0.4-desktop-banana05 ro
root=UUID=7446ae27-f2a4-41a0-b8d3-fdce0e298a30  hid_apple.iso_layout=0 quiet
splash=silent  initrd=boot\initrd-4.0.4-desktop-banana05

So with all 3 patches it works. To make life easier for people having the same
problem I'll upload my patch (integrating the 3) that applies to a 4.0.4
kernel.


Thanks a lot,

Tormen
