Hardware configuration
Accelerometer
It is a lsm303dlh
manufactured by STMicroelectronics. I did not succeed to make it work as of kernel version 3.1.6.
- There is a driver available at lkml.org, but there is a claim that it does not work. There is a patch here. There are instructions on that website, which I have not been able to follow.
- There are also some instructions for enabling the accelerometer available at the Ubuntu Forums.
Wireless
Works out of the box.
Webcam

Touchscreen
Detected by udev
as:
Bus 004 Device 002: ID 0eef:725e D-WAV Scientific Co., Ltd
Install the driver from the eGalax website. Since version 1.01.1014, the driver supports (two finger) multitouch input. Requires reboot.
Invert Y-axis
If after installing the eGalax driver the Y-axis of the touchscreen is inverted, edit the file /etc/eGTouchd.ini
an change the value of Direction
from 0 to 2:
/etc/eGtouchd.ini
... DetectRotation 0 Direction 2 Orientation 0 ...
Docking Station
A docking station is sold optionally with this computer. .Tablet Mode
(Un)folding detection
When this computer is folded (or unfolded) into a tablet, it sends a keystroke. You can assign the keys Template:Keypress and Template:Keypress to these keystrokes with the following commands, respectively:
setkeycodes e073 148 setkeycodes e074 149
Transparent cursor
Install xcursor-transparent-themeAUR, available in the Arch User Repository.
Hide mouse pointer in Gnome 3.x
Run the following commands as a normal user:
gsettings set org.gnome.desktop.interface cursor-theme "xcursor-transparent" & gconftool-2 --type string --set /desktop/gnome/peripherals/mouse/cursor_theme xcursor-transparent &
Hide mouse pointer in GDM
Create/edit the file /usr/share/icons/default/index.theme
with the following contents:
[Icon Theme] Inherits=xcursor-transparent
On-screen keyboards
Generic
Install florenceAUR, available in the Arch User Repository.
Gnome 3.2.x+
Install caribou, available in the Official Repositories.
Gesture recognition (with multitouch support)
Install easystroke-mtAUR, available in the Arch User Repository.
Screen rotation
The screen can be rotated with xrandr
, but the coordinates of the touchscreen are not rotated accordingly. You can fix this with xinput
by running the following commands:
xrandr -o left
xinput set-prop "eGalax Inc. USB TouchController" 'Coordinate Transformation Matrix' 0 1 0 1 0 0 0 0 1 xinput set-prop "eGalax Inc. USB TouchController" 'Evdev Axis Inversion' 0 1 xinput set-prop "eGalaxTouch Virtual Device for Multi" 'Coordinate Transformation Matrix' 0 1 0 1 0 0 0 0 1 xinput set-prop "eGalaxTouch Virtual Device for Multi" 'Evdev Axis Inversion' 0 1 xinput set-prop "eGalaxTouch Virtual Device for Single" 'Coordinate Transformation Matrix' 0 1 0 1 0 0 0 0 1 xinput set-prop "eGalaxTouch Virtual Device for Single" 'Evdev Axis Inversion' 0 1
xrandr -o right
xinput set-prop "eGalax Inc. USB TouchController" 'Coordinate Transformation Matrix' 0 1 0 1 0 0 0 0 1 xinput set-prop "eGalax Inc.

xrandr -o inverted
xinput set-prop "eGalax Inc. USB TouchController" 'Coordinate Transformation Matrix' 1 0 0 0 1 0 0 0 1 xinput set-prop "eGalax Inc. USB TouchController" 'Evdev Axis Inversion' 1 1 xinput set-prop "eGalaxTouch Virtual Device for Multi" 'Coordinate Transformation Matrix' 1 0 0 0 1 0 0 0 1 xinput set-prop "eGalaxTouch Virtual Device for Multi" 'Evdev Axis Inversion' 0 0 xinput set-prop "eGalaxTouch Virtual Device for Single" 'Coordinate Transformation Matrix' 1 0 0 0 1 0 0 0 1 xinput set-prop "eGalaxTouch Virtual Device for Single" 'Evdev Axis Inversion' 0 0
xrandr -o normal
xinput set-prop "eGalax Inc. USB TouchController" 'Coordinate Transformation Matrix' 1 0 0 0 1 0 0 0 1 xinput set-prop "eGalax Inc. USB TouchController" 'Evdev Axis Inversion' 0 0 xinput set-prop "eGalaxTouch Virtual Device for Multi" 'Coordinate Transformation Matrix' 1 0 0 0 1 0 0 0 1 xinput set-prop "eGalaxTouch Virtual Device for Multi" 'Evdev Axis Inversion' 0 0 xinput set-prop "eGalaxTouch Virtual Device for Single" 'Coordinate Transformation Matrix' 1 0 0 0 1 0 0 0 1 xinput set-prop "eGalaxTouch Virtual Device for Single" 'Evdev Axis Inversion' 0 0
Observe that the transformation matrix is the same for normal and inverted orientations, and for left and right orientations. Therefor the corresponding commands need to be applied only when changing between orientations with different transformation matrix.
Examples of Use
Script for rotating the screen
The commands above can be used to make a simple shell script for toggling the screen orientation between landscape and portrait as follows:
~/toggle_orientation.sh
#!/bin/bash rotation="$(xrandr -q --verbose | grep 'connected' | egrep -o '\) (normal|left|inverted|right) \(' | egrep -o '(normal|left|inverted|right)')" if [ $rotation = "normal" ] ; then xrandr -o left xinput set-prop "eGalax Inc. USB TouchController" 'Coordinate Transformation Matrix' 0 1 0 1 0 0 0 0 1 xinput set-prop "eGalax Inc. USB TouchController" 'Evdev Axis Inversion' 0 1 xinput set-prop "eGalaxTouch Virtual Device for Multi" 'Coordinate Transformation Matrix' 0 1 0 1 0 0 0 0 1 xinput set-prop "eGalaxTouch Virtual Device for Multi" 'Evdev Axis Inversion' 0 1 xinput set-prop "eGalaxTouch Virtual Device for Single" 'Coordinate Transformation Matrix' 0 1 0 1 0 0 0 0 1 xinput set-prop "eGalaxTouch Virtual Device for Single" 'Evdev Axis Inversion' 0 1 else xrandr -o normal xinput set-prop "eGalax Inc. USB TouchController" 'Coordinate Transformation Matrix' 1 0 0 0 1 0 0 0 1 xinput set-prop "eGalax Inc. USB TouchController" 'Evdev Axis Inversion' 0 0 xinput set-prop "eGalaxTouch Virtual Device for Multi" 'Coordinate Transformation Matrix' 1 0 0 0 1 0 0 0 1 xinput set-prop "eGalaxTouch Virtual Device for Multi" 'Evdev Axis Inversion' 0 0 xinput set-prop "eGalaxTouch Virtual Device for Single" 'Coordinate Transformation Matrix' 1 0 0 0 1 0 0 0 1 xinput set-prop "eGalaxTouch Virtual Device for Single" 'Evdev Axis Inversion' 0 0 fi exit 0
- Associate this script to a gesture using easystroke-mtAUR.
- Create a desktop launcher/system tray icon.
Script for toggling tablet mode ON and OFF (Gnome 3.x)
The following shell script hides the mouse pointer and activates Gnome 3.x's on-screen keyboard, caribou, when the netbook is fold into a tablet. It detects the current mode based on the current cursor theme (if the mouse is hidden, then the computer is in tablet mode). When you unfold the computer, it returns the screen to the default orientation.
Adwaita
, Gnome 3.x's default cursor theme is in use.~/toggle_tabletmode.sh
#!/bin/bash if [ $(echo $(gsettings get org.gnome.desktop.interface cursor-theme) | cut -c2- | sed 's/\(.*\)./\1/') = "xcursor-transparent" ] ; then gsettings set org.gnome.desktop.interface cursor-theme "Adwaita" & gconftool-2 --type string --set /desktop/gnome/peripherals/mouse/cursor_theme Adwaita & dconf write /org/gnome/desktop/a11y/applications/screen-keyboard-enabled false & xrandr -o normal xinput set-prop "eGalax Inc.
