Dell Vostro 3300 backlight keys

[Albert Cervin]

Hi all!

Thanks for a great operating system, coming from Linux certainly feels
liberating :)

I have some small problems though and one of them is that I cannot control
backlight on my laptop, a Dell Vostro 3300. This worked under Linux when
using acpi_video=legacy kernel parameter (if this helps). I have kldloaded
acpi_video and I have hw.acpi.video.lcd0.brightness listed under sysctl but
changing it has no effect at all.

I would like some guidance where I can look to find a solution or help you
guys identify the problem. I am also a developer myself so even though I am
a FreeBSD newbie I can still understand technical details :) I know also
that there might be other solutions to the problem (that only works under
X) but I am interested in a more universal solution.

Would appreciate any help! Thanks in advance!
