Comment 9 for bug 212733

A reply from Danny Kukawka:
"1) you can't run the HAL scripts manually, they are supposed to be called by
HAL only

2) proc isn't supported by HAL anymore, at least not the interfaces from the
generic video module

3) where is the output of lshal? Which desktop environment was used?

4) the two keyevents for brightness are from the kernel. HAL can't do anything
here

5) try to unload the video module and use the dcdbas module instead, which
allow the whole brightness handling especially for Dell machines."

Would you please test the things he suggests and add the commands he requests?
Thanks in advance.
