Experience has shown that different Fujitsu laptops use incompatible ways of
controlling the brightness via software. The fujitsu-laptop module in 2.6.25
knew of the method required by the S7020 and *some* other S-series laptops.
However, this did not work for the S6410 (for example), among others.
Thanks to the work and debugging efforts of an S6410 user, 2.6.27 will have
support for the brightness control method used on the S6410. It is however
impossible to know which other Fujitsu models this new method will work with.
We'll just have to try it and see. It will most likely work with some other
S-series laptops. This bug report does not relate to an S-series laptop, so
the best I can say is that the new code may work - I certainly can't guarantee
it at this stage.
Therefore in the first instance I would ask that you try kernel 2.6.27-rc1 when
it is released and report what - if anything - has changed. If 2.6.27-rc1
still doesn't work it indicates that your Fujitsu laptop uses yet another
method for controlling the LCD brightness via software. We can evaluate the
next step once we know what 2.6.27-rc1 does.
