Configuration

Clickpad

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.

Install xf86-input-synaptics-clickpad from the AUR.

Video

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

Extended:

xrandr --output LVDS1 --auto --output HDMI1 --auto --right-of LVDS1

Disable Second Monitor

xrandr --output LVDS1 --output HDMI1 --off

Check out the xrandr man page for more info

Ethernet

  1. Use the r8168 module in the Official Repositories
  2. Blacklist r8169 (follow pacman install message)
  3. Add r8168 to rc.conf

There are some issues with the r8169 module:

  • Kernel 3.1.5: Does not work
  • Kernel >= 3.1.4: Mileage may vary, typically can't reconnect

Wireless

Intel Centrino Wireless-N 1000

Works out of the box. Module: iwlagn

Sound

Works out of the box. Module: snd-hda-intel

Webcam

Works out of the box. Tested using Skype

Power

Suspend and Hibernation both work using pm-utils Note: Hibernation did not work on 2.6.38.2 (works with 2.6.38.3)

Troubleshooting

Delay with Space Bar

Solution: Update BIOS (at least 1.08)

Trackpoint is NOT detected or is detected after X minutes

This appears to be a kernel bug. See: https://bugzilla.kernel.org/show_bug.cgi?id=33292

A workaround is passing proto=bare to the psmouse module. However this disable scrolling with the clickpad and the two finger middle click.

modprobe psmouse proto=bare
