Bug Description
Sony TX series and possible many other Sony laptops couldn't use the lowest brightness setting because the default sony_acpi.c restrict the lowest value to one instead of zero. This could save some energy so the difference between Linux and Windows isn't that high any more. I have always patched the sony_acpi.c on my own but since this module isn't integrated in linux.source anymore it is much more harder without recompiling the whole kernel. If there is any Sony laptop which haven't zero as the lowest value it should be no problem since a bug in /etc/acpi/
Of course the /etc/acpi/

The spicctrl entry makes no sense for me and results at least on sony_acpi Laptops in a bug (sets brightness on the lowest option to 33 (which is out of bound 0-8)) so I have removed it.
