xbacklight doesn't worked here.
still, this:
BRIGHTNESS=$(cat /sys/class/backlight/sony/actual_brightness)
if [ "$BRIGHTNESS" -gt 8 ]; then
BRIGHTNESS=1
fi
if [ "x$1" = "xdown" ]; then
if [ "x$BRIGHTNESS" != "x1" ]; then
BRIGHTNESS=$(( $BRIGHTNESS - 1 ))
echo $BRIGHTNESS > /sys/class/backlight/sony/brightness
else
[ -x /usr/bin/spicctrl ] && /usr/bin/spicctrl -b 0
fi
# Recent nvidia Sonys have ACPI methods that do nothing. Thanks, Sony.
[ -x /usr/bin/smartdimmer ] && smartdimmer -d 2>/dev/null
elif [ "x$1" = "xup" ]; then
if [ "x$BRIGHTNESS" != "x8" ]; then
BRIGHTNESS=$(( $BRIGHTNESS + 1 ))
echo $BRIGHTNESS > /sys/class/backlight/sony/brightness
fi
[ -x /usr/bin/smartdimmer ] && smartdimmer -i 2>/dev/null
else
echo >&2 Unknown argument $1
fi
with sony_pi and sony_laptop loaded worked.

Just install Arch and have the same problem
I couldn't even find xbacklight
pacman -Ss xbacklight returns nothing
I'd read the faq
and the wiki
then the guides
and went googling, before posting here

Do you have any Fn keys that are supposed to take care of backlight setting?
If so you could add ACPI events to /etc/acpi, preferably in separate files. I have a TZ 190N myself and patched the handler script. Check my patch for examples (I made this patch for my model specifically so no guarantee whatsoever it will work for you).
