Docking Station
A docking station is sold optionally with this computer.
The docking station is an apparant PCI bus, connected from the bottom of the computer, that adds two USB, one audio, and one 10/100 hardwire 10/100 ethernet port.
Tablet Mode
The instructions above make the 1090 a fully-working netbook. To take advantage of this hardware, some tablet-related features need to be configured.
(Un)folding detection
When this computer is folded (or unfolded) into a tablet, it sends a keystroke. You can assign the keys XF86LAUNCH1
and XF86LAUNCH2
to these keystrokes with the following commands, respectively:
setkeycodes e073 148 setkeycodes e074 149
/etc/rc.local
to execute them when booting.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 keyboard
Generic
Install florenceAUR, available in the Arch User Repository.
Gnome 3.2.x
Gesture recognition
Install easystrokeAUR, This package does not work properly with multitouch. When the screen is touched with two fingers it is interpreted at a gesture given by the line defined between the two points of contact.
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:
xinput --list
, which may change on driver updates for the touchscreen.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.

xrandr -o right

xrandr -o normal

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, see also #Screen rotation:
~/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.

- Create a desktop launcher/system tray icon to run this script.
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 cursor 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. See also #Screen rotation.~/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.
