How about you provide some information on what laptop/keyboard you use? There are several applications you can try:

yaourt keyboard light
#or search AUR from your browser

Probably you can adjust it what you already have on our system.

Sanity check... Please post the output of uname -a and of pacman -Qi linux

I think that is good, the results are this:

uname -a

I agree, I was ensuring that the kernel you are running is the kernel that is installed.
It is.

Patofet, your keyboard comes from SteelSeries. The keyboard light is a rgb light (I assume from the pictures). These information should have come from you by the way.
Since I never used such devices, I can only guess. It probably uses some modules (try lsmod | egrep -i 'light|rgb|kbd'), maybe they are not loaded any more for whatever reason. Or it got disabled after a recent upgrade. Check for any pacnew files in /etc. Maybe xset can set the light on again.

xset led n #where n is the appropriate number
#or try turning every led on
for i in $(seq 32); do xset led $i;done

Although I doubt this will do anything, rgb should be somewhat more complex. Try to find out what controller your laptop uses for the light.
How did it work before? Constant light, pulsing, some transitions? Are there any options in the BIOS/UEFI for it?

Hi, thanks for your reply, it's not a rgb light simple white light(two positions, all keyboard or only 'wasd' part). when I try "for i in $(seq 32); do xset led $i; sleep 1;done" it does nothing only disables numeric-keyboard and I must restart computer >.<

lsmod | egrep -i 'light|rgb|kbd'

Search for any related modules (options), look through devices (tree /dev) and processes (/proc). Since it is the simpler version of backlight SteelSeries produces, it probably uses something primitive to turn on/off and change states. Using "xset -led n" (with a hyphen before led) would have disabled the LEDs again. You might also look how other manufactures are handling their lights (alien for example). Looking through lspci and dmidecode might turn up something useful. Since SteelSeries usually uses USB, it might use an internal port for power.
Or just ask SteelSeries/MSI how its product is handled under GNU/Linux, although they may just say it is not supported.
