900X3E Fn keys
Posted: 11 Oct 2013, 20:27
I can't get the Fn keys for brightness & keyboard backlight working. Tested on both Debian Wheezy / Jessie and both kernel 3.10 / 3.11 with samsung_laptop loaded.
Fn keys for touchpad, mute, volume +/- work out of the box, also samsung-tools works just fine. samsung_backlight also loads - what is this good for btw?
I can adjust brightness by echoing /sys/class/backlight/acpi_video0/brightness or change the keyboard backlight by echoing /sys/devices/platform/samsung/leds/samsung\:\:kbd_backlight/brightness however not by Fn keys.
The keys themselves seem to be mapped correct, see the Fn+F10 (keyboard backlight +) output for example:
I have absolutely no idea where I should look next. Any help appreciated.
