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.
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: KeyPress event, serial 38, synthetic NO, window 0x7c00001, root 0x163, subw 0x0, time 335211652, (79,64), root:(79,960), state 0x10, keycode 238 (keysym 0x1008ff05, XF86KbdBrightnessUp), same_screen YES, XLookupString gives 0 bytes: XmbLookupString gives 0 bytes: XFilterEvent returns: False KeyRelease event, serial 38, synthetic NO, window 0x7c00001, root 0x163, subw 0x0, time 335211652, (79,64), root:(79,960), state 0x10, keycode 238 (keysym 0x1008ff05, XF86KbdBrightnessUp), same_screen YES, XLookupString gives 0 bytes: XFilterEvent returns: False KeyPress event, serial 38, synthetic NO, window 0x7c00001, root 0x163, subw 0x0, time 335213754, (79,64), root:(79,960), state 0x10, keycode 237 (keysym 0x1008ff06, XF86KbdBrightnessDown), same_screen YES, XLookupString gives 0 bytes: XmbLookupString gives 0 bytes: XFilterEvent returns: False KeyRelease event, serial 38, synthetic NO, window 0x7c00001, root 0x163, subw 0x0, time 335213754, (79,64), root:(79,960), state 0x10, keycode 237 (keysym 0x1008ff06, XF86KbdBrightnessDown), same_screen YES, XLookupString gives 0 bytes: XFilterEvent returns: False
This is not a kernel issue, apologies for my retardedness: https://bugs.kde.org/show_bug.cgi?id=288179
