Hardware

Infrared receiver

First shutdown computer, reboot and enter the BIOS by pressing F2. Find the Infrared option, enable it (it is disable by default!) and set it to COM2. Visit LIRC's webpage and download their latest CVS snapshot. Extract, go into directory and run setup.sh :

> wget http://lirc.sourceforge.net/software/snapshots/lirc-0.8.1pre3.tar.bz2
> tar -jxvf lirc-0.8.1pre3.tar.bz2
> cd lirc-0.8.1pre3
> ./setup.sh

Then select :

1 Driver configuration
--> 6 IrDA hardware
   --> 1 SIR IrDA (built-in IR ports)
3 Save configuration & run configure

Now make it :

make && sudo make install

Be sure you do not have the irdautils package. It blocks the serial port. You will need to load the "lirc_sir" module. If you got error like :

lirc_sir: i/o port 0x02f8 already in use.

in dmesg, run this command as root :

# /bin/setserial /dev/ttyS1 uart none

then try again to modprobe "lirc_sir". If it works, create the file "/etc/modprobe.d/lirc" and put is that line :

install lirc_sir /bin/setserial /dev/ttyS1 uart none; /sbin/modprobe --ignore-install lirc_sir

This will run the command above each time you try to modprobe the "lirc_sir" module. Add the module to autoload (/etc/modules).

Now continue as the installation procedure of lirc.


Power Management

I suggest you read Gentoo Power Management Guide for great information. After some work on this I wanted to add some information specific to the I8500.

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.
