=Networking=

==Wired Ethernet==
+
 
+
If you have problems with the Ethernet card, you'll have to load the modules {{ic|broadcom}} then {{ic|tg3}}. Add to the end of {{ic|/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
+
 
+
===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=
+
Adjusting the backlight requires additions to the kernel boot options.
+
 
+
Add ''acpi_osi=Linux acpi_brightness=vendor'' to /boot/grub/menu.lst
+
 
+
# # (0) Arch Linux
+
# title  Arch Linux
+
# root  (hd0,1)
+
# kernel /vmlinuz26 root=/dev/sda7 ro ''acpi_osi=Linux acpi_brightness=vendor''
+
# initrd /kernel26.img
+
 
+
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.
