Networking

Wired Ethernet

If you are running into problems to get ethernet working on install you will have to reload tg3 module.

 modprobe -r tg3
 modprobe tg3
 dhcpcd <name of your ethernet interface>


If you have problems with the Ethernet card, you'll have to load the modules broadcom then tg3. Add to the end of /etc/modprobe.d/modprobe.conf:

 softdep tg3 pre: broadcom

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

Xorg

You'll want xf86-video-intel

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

Issues

Adjusting the backlight requires additions to the kernel boot options.

Add acpi_osi=Linux acpi_brightness=vendor to kernel parameters.

The Fn + Left/Right Arrow keyboard combinations will now decrease/increase the backlight.

Adding

 echo 450 > /sys/class/backlight/intel_backlight/brightness

to /etc/rc.local will adjust the backlight brightness down during boot.
