Hi,

here on a Sony Vaio BZ11XN (Intel X4500MHD), the back light doesn't work (it is @100% at boot, and Fn-F5/F6 do not work). After having followed #258994 (which I encountered too), i came here.

The rc.local/xrandr + manual xbacklight trick works. I didn't try to alter the /etc/acpi/ script yet, but I will.
On my up-to-date intrepid, the

xrandr --output LVDS --set BACKLIGHT_CONTROL native

command works as expected and doesn't produce any error.
