3D acceleration

[brunomaximom@openmailbox.org]

Hi,
Definitivaly here on my laptop I cannot have 3D acceleration with intel 
driver.
I have hybrid graphics (intel and radeon), but kldload i915kms returns 
black screen and unusable operating system that I need to reboot.
That's really needing a fix.
And how I reduce the brightness of my screen on it? Fn keys do not work 
on it.
Bye thanks.
