Installation notes

For Debian squeeze.

CPU

Frequency scaling and temperature monitoring work out of the box.

Network

Both wired and wireless network work.

On my machine, Network manager said "device not managed" for wired connection. After switching to wicd, wired network works out of box. I need to manually specify wlan0 in wicd-client GUI, (Preferences -> General Settings -> Network Interfaces -> Wireless interface) to make wireless work.

Display

After the first boot the display had a resolution of 800×600.

For native resolution, we need to install IntelEmbeddedMediaGraphicsDriver.

Touchpad

Only basic features tested.

Touchscreen

only single touch working. (raw data in /dev/usb/hiddev0, but only single-touch events)

multitouch needs xserver upgrade (Multitouch)

DVB-T

Not tested yet.

Webcam
