The SZ series have a stamina/speed switch switch between 2 video cards.
Usually one is an NVidia (for speed) and one is an Intel (for stamina).
On the NVidia there is nothing we can do (you can try nvclock or any
nvidia proprietary tool as documented on my wiki[1]), while for the
Intel card it's a different story (again documented on my wiki).
If you have no luck with the sony-laptop provided backlight control you
can try xbacklight that, as far as I can see[2], should work on your
Intel chipset.
hope this helps

Hi,
the backlight now is working with the Intel chipset. But the workaround
had some sideeffects: Now the lidswitch is unfunctional. :/
I tried to find out if it works by running acpi_listen but the lidswitch
generates no events...
Any ideas?
regards
sebastian
