I am trying to get the Fn+F7 and Fn+F8 keys working on my Samsung laptop, model 90X3A. These map to 'keyboard illumination down' and 'keyboard illumination up', which sets the brightness of the LEDs behind the keyboard. I have started a thread here http://ubuntuforums.org/showthread.php?t=1751914 about this issue I have managed to get the scan code (0x96 and 0x97) to respond with the correct key code (kbdillumup and kbdillumdown) when I run /lib/udev/keymap -i input/event4 However the keyboard backlight level still does not change when these buttons are pressed. According to /usr/share/doc/udev/README.keymap.txt.gz, step 6 says I should email this list with some info as listed below. > 6. Send the system vendor/product names, the key mapping from step 2, > and /tmp/udev-db.txt from step 4 to the linux-hotplug@xxxxxxxxxxxxxxx mailing > list, so that they can be included in the next release. === Vendor and product names === Vendor SAMSUNG ELECTRONICS CO., LTD.
