## Hardware configuration

### Accelerometer

According to this source, model name is `LSM303DLH`. Only partial configuration has been achieved so far, athough the cited source claims to have full support of the accelerometer. See STMicroelectronics LSM303DLH Accelerometer/Magenetometer.

### Wireless

Works out of the box.

### Webcam

Detected by `udev` as

    Bus 001 Device 002: ID 0bda:58f4 Realtek Semiconductor Corp.

Works out of the box. Uses the `uvcvideo` module, see Kernel modules and Webcam setup.

### Graphics controller

Install the xf86-video-intel package. See Intel.

### Touchpad

Install the xf86-input-synaptics package.

### Bluetooth

Uses `bluetooth` daemon, see Daemon.

### Speakers

Uses `snd-hda-intel` module, see Kernel modules.

### HD video playback

Install crystalhd-gitAUR[broken link: archived in aur-mirror], available in the Arch User Repository. The new module is located in

    /lib/modules/$(uname -r)/kernel/drivers/video/broadcom/crystalhd.ko

Unload the staging module `crystalhd` and load the new one, see Kernel modules.

### Touchscreen

Detected by `udev` as:

    Bus 004 Device 002: ID 0eef:725e D-WAV Scientific Co., Ltd

For configuration, see Multitouch displays.

### Docking Station

A docking station is sold optionally with this computer.

This article or section needs expansion.

Reason: please use the first argument of the template to provide a brief explanation. (Discuss in Talk:Dell Inspiron 1090 (Duo)#)

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

Tip: Add those commands to `/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

Warning: This will also hide the pointer in all Qt applications (you can only see the arrow pointer, secondary pointers as hand, beam or move will be invisible).

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

Install the caribou package.

### Gesture recognition

Install easystroke-mtAUR[broken link: archived in aur-mirror], available in the Arch User Repository. It has multitouch support.

Note: easystroke (also available in the Arch User Repository 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:

Warning: This commmands depend on the output of `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. 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. USB TouchController" 'Evdev Axis Inversion' 1 0
    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' 1 0
    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' 1 0

    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, 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. 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

Tip: For an improved user experience you can:

- Associate this script to a gesture using easystroke-mtAUR[broken link: archived in aur-mirror], see #Gesture recognition.
- 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.

Note: It assumes xcursor-transparent-themeAUR and caribou are installed, see #Transparent cursor and #On-screen keyboard; and that `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. 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
    else
        gsettings set org.gnome.desktop.interface cursor-theme "xcursor-transparent" &
        gconftool-2 --type string  --set /desktop/gnome/peripherals/mouse/cursor_theme xcursor-transparent &
        dconf write /org/gnome/desktop/a11y/applications/screen-keyboard-enabled true &
    fi
    exit 0

Tip: You can run this script when (un)folding the netbook associating it to the keys `XF86LAUNCH1` and `XF86LAUNCH2`, see #(Un)folding detection.
