For the life of me I haven't been able to control the brightness of my display in FreeBSD on this laptop, well untill a couple days ago I managed to be able to do it with a sysctl variable w/
	
	
	
		
However, the Fn+F7 (Brightness Down) and Fn+F8 (Brightness Up) keys would not work... even with
	
	
	
		
and I even tried this in my rc.conf:
	
	
	
		
I think the variable I used in FreeBSD was 
	
	
	
		
where x was one of the available numbers in another hw.acpi.video.0.* variable.
Whats weirder is that F7 and F8 work on PC-BSD with no acpi_video loaded:
	
	
	
		
And PC-BSD's /boot/loader.conf:
	
	
	
		
I don't think wpi loaded on FreeBSD, except MAYBE when I loaded acpi_hp, but then i think it may have been acpi_hp_wpi. Anybody have any ideas? Also, can FreeBSD use DSDTs from linux or PC-BSD? Because this laptop works with both of those OS's. I'll also post the dmesg for PC-BSD. If anybody has any suggestions please let me know. I can also post "sysctl -a" from PC-BSD or anything else you might need, just let me know. Unfortunately, I don't have both FreeBSD and PC-BSD on here anymore due to not being able to resize UFS but I know what I had in most of my config files if you have any questions there. Thanks in advance.
