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.
