Networking

Wired Ethernet

If you have problems with the ethernet, you'll have to load the modules broadcom then tg3 in /etc/rc.conf

 MODULES=(broadcom tg3 ...)

or add to the end of /etc/modprobe.d/modprobe.conf

 install tg3 /sbin/modprobe broadcom; /sbin/modprobe --ignore-install tg3


Wireless

The Atheros WLAN chip is fully supported by ath9k, which is automatically loaded at boot with no need to add it in /etc/rc.conf.

You can manage your wireless connections with NetworkManager or Wicd.

Power Management

CPU frequency scaling

The laptop-mode-utils way

You probably want to use laptop-mode-utils with acpi.

# pacman -S laptop-mode-utils acpi

Another method

In /etc/rc.conf, add the following modules :

[...]

MODULES=( ... acpi-cpufreq cpufreq_ondemand)

[...]

And put the following lines in /etc/rc.local :

[...]

echo "ondemand" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo "ondemand" > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor
echo "ondemand" > /sys/devices/system/cpu/cpu2/cpufreq/scaling_governor
echo "ondemand" > /sys/devices/system/cpu/cpu3/cpufreq/scaling_governor

Xorg

You'll want xf86-video-intel

You'll get a really jumpy touchpad if you do not install xf86-input-synaptics

Issues

You won't be able to adjust brightness under linux.

Temporary fix: add acpi_osi= to /boot/grub/menu.lst
