Configuration

CPU

Works out of the box.

Follow the CPU Frequency Scaling guide to enable speed-stepping. Processor has Intel Turbo Boost which works out of the box, but you can't see the frequncies above 2.5GHz in /proc/cpuinfo. To see the actual frequency use i7z package.

  • energy save: cpufrequtils (800Mhz-2.5Mhz)

Video

Intel

Follow these guides: Xorg and Intel

Not tested: VGA out and HDMI.

Audio

Follow the official documentation: ALSA and Pulseaudio

In order to make integrated speakers work add to /etc/modprobe.d/modprobe.conf:

options snd-hda-intel index=0 model=auto

And to /etc/modprobe.d/sound.conf add:

alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel

Touchpad

Follow the Synaptics guide.

Webcam

Working, you may install cheese(with gstreamer-0.10-plugins) to view.

Function keys

  • workable
* Fn+F3: Toggle Wifi (or use slider on right-bottom corner of keyboard)
* Fn+F4: Suspend to ram
* Fn+F6: Toggle back-light to save battery
* Fn+F7: Toggle touchpad
* Fn+Left/Right adjust back-light (XF86MonBrightnessDown/XF86MonBrightnessUp) (add acpi_osi=Linux option on linux boot)
  • Failed Fn keys
* Fn+F5 toggle VGA (XF86Display)
* Fn+F8 toggle speaker (XF86AudioMute)
* Fn+Up/Down adjust speaker volume (XF86AudioRaiseVolume/XF86AudioLowerVolume)
