Kudos to Fujitsu for getting back to you so quickly with a > working solution. That's great news. Thanks to all who have pursued this issue. At least now we have some understanding as to what's going on behind the scenes on this hardware, even it if it rather convoluted. > ...though if you think about it, the whole thing is absolutely hideous: > an *ACPI* driver requires cooperation from a *video* driver to notify > the operating system about a *key press*. Yeah. On one hand I'm utterly amazed. On the other, I've seen and read about other really bizarre things which go on in the BIOSes of computers over the years, so nothing really surprises me anymore. :-) My understanding based on this latest information is that the patch to the i915 driver fixes the brightness control on these laptops and that no changes to fujitsu-laptop are required for this. Is this correct? As to the touch keys, it sounds like this might be a BIOS thing to - is it?
