You didn't mention which kernel has this issue. Based on the date, I'm going to guess it's a 3.1 based kernel. Do the 3.2.7 or newer kernels help this at all? All the kernels, even 3.3-rc4 (my current kernel), have this issue. The keypresses are detected correctly... it's just that they do nothing. They have no effect:

This is not a kernel issue, apologies for my retardedness: https://bugs.kde.org/show_bug.cgi?id=288179 (In reply to comment #4) > This is not a kernel issue, apologies for my retardedness: No problem. We all make mistakes sometimes. |
Description of problem: Function keys Fn+F3 and Fn+F4 (XF86KbdBrightnessDown/Up) do not change the keyboard backlight intensity. Key to turn off keyboard backlight (keycode 248, upper left corner on keyboard) powers off the backlight, but doesn't power it back on. Version-Release number of selected component (if applicable): Latest stable update How reproducible: Always The kernel DOES support the backlight in the keyboard as an LED class driver -- but the Asus WMI kernel module does not associate it with the keyboard keys. cat g73-keyblight #!/bin/sh set -e current=`cat /sys/class/leds/asus::kbd_backlight/brightness` echo "current light level: $current" if [ -n "$1" ] then current=$(($current $1)) echo "new light level: $current" echo $current > /sys/class/leds/asus::kbd_backlight/brightness fi I can provide all the info you need.
