TC4200 Ambient Light Sensor w/ Linux
OK, I have to be the dumbest geek ever to walk the planet. I've been going
crazy trying to figure out what I need to do on this laptop to get the ambient
light sensor to actually work. I even posted on LQ Forums. My answer was:
"Did you try Fn + F11? It works on mine."
And, sure enough, it works on mine too. Perhaps this is all I need to do on my
work PC with Vista on it. When I had XP on it I actually needed a driver to
make it work. HP never released a Vista driver so I assumed it just wouldn't
work.
...
Well, look at that. It works on Vista too. I wonder why XP needed a driver
at all? It sure seems to be a hardware level feature rather than something
that requires software to make it work. Perhaps the XP bits were just to
control the on/off status of the sensor via a GUI interface rather than having
to use the physical keyboard?
Whatever. At least it is working now.
