Subject: Brightness control for MacBook Pro - Nvidia 9400
Date: Thu, 11 Feb 2010 21:38:45 +0100 [thread overview]
Message-ID: <1265920725.7103.7.camel@no> (raw)

Dear all,
I am booting a MacBookPro5,3 using elilo and efifb. Now I'd like to use
pommed to control display brightness (which won't work). Digging around
in mbp_nvidia_bl.c I figured out that tries to control the geforce 9600M
instead of the currently active geforece 9400m
02:00.0 VGA compatible controller: nVidia Corporation G96 [GeForce 9600M GT] (rev a1)
03:00.0 VGA compatible controller: nVidia Corporation C79 [GeForce 9400M] (rev b1)
Does anyone have an idea which bytes to tweak to change brightness
levels for the 9400? Seems like 0x52f does not work - at least
setpci -s 03:00.0 0x52f.B=10 fails...
Thanks!
Soeren
