[ddccontrol-users] nvidia geforce go 6200 tc / general laptop support

[chris k. <ck...@ph...>]

Hi all,

I'm new to list and have a question concerning the support of laptop
devices (if it is technically possible to control a laptop via
ddccontrol at all):
Sony's (PCG-VGN-)S3XP (Pentium-M, 13.3" xblack-display, NVIDIA Geforce
Go 6200 TC) uses the NVIDIA-driver to set the brightness under windows,
yet under Linux, the common drivers (sonypi, sony_acpi) have no effect
on the brightness-settings. Today I've received a mail from a person,
who stated, the LCD-brightness was controlled by DDCCI (instead of ACPI,
which most people expected), so at least the problem seems to be
identified. Still, I have no clue how to get ddccontrol to detect any
hardware, this is the output I get (with/without rivafb-module):

http://server1.nordic-it.de/~viper/output_ddccontrol_norivafb
http://server1.nordic-it.de/~viper/output_ddccontrol_rivafb

Software employed on the machine is Gentoo Linux, kernel 2.6.11
(vanilla; i2c ist present, rivafb has ddcci-support enabled),
NVIDIA-Linux-x86-1.0-7664, Xorg 6.8.2 (Option "Allow DDCCI" is set to
true), ddccontrol 0.1.2 (not cvs).

Additional info on the system:

Thanks in advance and best regards

Sry, if the mail contains traces of html, I'm not sure, whether
