Wired NIC:

Wireless NIC: Intel IPW 2200


To get all the things working, use Beyond kernel...



Works fine using the tg3 module.


Install driver:

pacman -S extra/ipw2200-fw 

Get WiFi LED signalization working:

echo "options ipw2200 led=1" > /etc/modprobe.conf

Power Management


Install ACPI daemon and start it.

# pacman -S acpid
# /etc/rc.d/acpid start

Also add acpid to the DAEMONS line in you /etc/rc.conf (note that this is not necessary if you already have hal in there since acpid has been added to its starting script).

I found out that when booted with ACPI on, the laptop makes kind of high frequency noise which can be really annoying when you work in otherwise quiet room. There is no such noise when you boot with acpi=off. I searched for a solution and I found this:

Pass this to the kernel by changing your /boot/grub/menu.lst (the whole entry should look something like this):

title  Arch Linux Beyond
root   (hd0,0)
kernel /vmlinuz26beyond root=/dev/hda3 ro pci=bios idle=halt acpi_sleep=s3_bios
initrd /kernel26beyond.img

Many thanks for the trick should go to andreas_mauser on ubuntu forums [1].

CPU frequency scaling

There are various ways how to do this (see e.g. SpeedStep), but I like this one:

Install cpufrequtils

# pacman -S cpufrequtils

Edit /etc/conf.d/cpufreq

#configuration for cpufreq control

# valid governors:
#  ondemand, performance, powersave,
#  conservative, userspace

# valid suffixes: Hz, kHz (default), MHz, GHz, THz

Load the speedstep_centrino module using modprobe. Alternatively, you can add it to the MODULES list in /etc/rc.conf to load it at boot time. Don't forget to add cpufreq to the DAEMONS array.

 	Option        "SHMConfig"     "true"
#  	Option        "Repeater"      "/dev/ps2mouse"

To use this you'll need to change your InputDevice line in your "ServerLayout" section to use the synaptics mouse....todo...
