The clickpad works with the xf86-input-synaptic driver from extra, but the left/right click buttons at the bottom of the clickpad do not work.

In order to use the builtin intel graphics adapter you will have to install the corresponding drivers:

# pacman -S xf86-video-intel

Dual Monitors

Clone: xrandr --output LVDS1 --auto --output HDMI1 --auto --same-as LVDS1
