To do

Kernel

Works with 2.6.28 out of the box.

X.org

This is my working xorg.conf:

NVIDIA GeForce 8600M GT

Hardware

Power Management

I suggest you read Gentoo Power Management Guide for great information.

Suspend and Resume

Suspend and resume works 100% with kernel26-ice from AUR, even with the NVIDIA binary driver (tested with 180.29).

I have not tried hibernation yet.

CPU Throttling

Modprobe the modules :

  • cpufreq_conservative
  • cpufreq_ondemand
  • cpufreq_userspace
  • cpufreq_powersave

Then set the governor by using cpufreq-set. For ondemand :

# cpufreq-set -g ondemand

For performance (higher frequency):

# cpufreq-set -g performance

For powersaving (lower freqency) :

# cpufreq-set -g powersave

ACPI

To turnoff the computer when you press the power button, put the following in /etc/acpi/handler.sh

button/power)
       case "$2" in
           PBTN)
                   logger "PowerButton pressed: $2"
                   halt
           ;;
           *)    logger "ACPI action undefined: $2" ;;
       esac

Replace the "halt" line with the shutdown command of your choice.


To turn off the backlight of an ATI Radeon Mobility card, put the following in /etc/acpi/handler.sh

button/lid)
       case "$2" in
           LID)
               logger "ACPI button/lid action"
               STATE=`radeontool light`
               case "$STATE" in
                   "The radeon backlight looks on") radeontool light off ;;
                   "The radeon backlight looks off") radeontool light on ;;
               esac
               ;;
       esac
       ;;

This requires that you have the radeontool package installed (it is in AUR). You also need to add "acpid" to the DAEMONS array in /etc/rc.conf.
