The Fn+F8 and Fn+F9 keys are not working on my Clevo W350ST with Kubuntu
Raring to change screen brightness of the internal laptop screen. I
installed linux-headers-3.11.0-4, linux-headers-3.11.0-4-generic,
linux-image-3.11.0-4-generic and linux-image-extra-3.11.0-4-generic
from Saucy packages repository but the problem persists.

When trying:

$ xev | sed -n 's/^.*state \([0-9].*\), keycode *\([0-9]\+\) *\(.*\), .*$/keycode \2 = \3, state = \1/p'                                                            
keycode 36 = (keysym 0xff0d, Return), state = 0x10                                           
keycode 232 = (keysym 0x1008ff03, XF86MonBrightnessDown), state = 0x10                       
keycode 233 = (keysym 0x1008ff02, XF86MonBrightnessUp), state = 0x10

Event codes appear correctly.

And changing:

/sys/class/backlight/intel_backlight/brightness

changes the brightness of the screen, but pressing the key combination
does not. I believe this happens because the key combination is, in
fact, changing the value of

/sys/class/backlight/acpi_video0/brightness

I have

http://ppa.launchpad.net/xorg-edgers/ppa/ubuntu
http://ppa.launchpad.net/bumblebee/stable/ubuntu

in my package sources

Thanks!
