As of kernel 3.8.0-25-generic, backlight is not properly working for me (xps ubuntu edition, 13.04 kubuntu clean install). With the workaround echo 0 > /sys/class/backlight/intel_backlight/brightness the brightness keys work, but the on screen display isn't shown when changing brightness. However, changing brightness via the slide in the energy settings does show the osd.
