# Touchpad

[1] Hi, I want to share my xorg config to solve this problem (xinput is not the best approach ;P) so, on /etc/X11/xorg.conf you will find something like this:

    Section "ServerLayout"
            Identifier     "X.org Configured"
            Screen      0  "Screen0" 0 0
            InputDevice    "Mouse0" "CorePointer"
            InputDevice    "SynapticsTouchpad" "SendCoreEvents"
            InputDevice    "Keyboard0" "CoreKeyboard"
    EndSection

(...) Remove (or comment) line 4 and 5, also you may remove the respective Section "InputDevice"s. You do not want this because you have /etc/X11/xorg.conf.d/10-synaptics.conf so lets add some options there, this is my configuration (I've an Acer AS1410 laptop):

    Section "InputClass"
            Identifier "SynapticsTouchPad"
            Driver "synaptics"
            MatchIsTouchpad "on"
            MatchDevicePath "/dev/input/mouse*"
            Option "TapButton1" "1"
            Option "TapButton2" "2"
            Option "TapButton3" "3"
            Option "EmulateTwoFingerMinZ" "50"
            Option "EmulateTwoFingerMinW" "10"
            Option "AccelFactor" "0.01"
            Option "MinSpeed" "1.3"
            Option "MaxSpeed" "1.9"
    EndSection

Thats all, you only need to restart X ps: check /var/log/Xorg.0.log if something is not working

# Touchscreen

When you rotate the touchscreen and want to rotate the desktop, the touchscreen calibration is messed up. I have two scripts to rotate it and rotate it back. They also recalibrate the touchscreen. You can bind them to some key.

## rotate

    #!/bin/bash
    device=`xinput list | grep Cando | grep -o 'id=[0-9]*' | sed 's/id=//'`

    xrandr --output LVDS1 --rotate left

    xinput set-prop --type=int --format=8 $device "Evdev Axes Swap" 1
    xinput set-prop --type=int --format=8 $device "Evdev Axes Inversion" 1 1
    xinput set-prop --type=int --format=32 $device "Evdev Axis Calibration" 10751 0 19 18925

## rotate back

    #!/bin/bash
    device=`xinput list | grep Cando | grep -o 'id=[0-9]*' | sed 's/id=//'`

    xrandr --output LVDS1 --rotate normal

    xinput set-prop --type=int --format=8 $device "Evdev Axes Swap" 0
    xinput set-prop --type=int --format=8 $device "Evdev Axes Inversion" 0 0
    xinput set-prop --type=int --format=32 $device "Evdev Axis Calibration" 1 18873 44 10751

# Webcam

Works out of the box

    mplayer tv://

As mentioned in Acer Aspire Timeline 1810tz#Webcam[broken link: invalid section] you can add !uvcvideo to rc.conf modules to prevent webcam from auto loading to save power.

I use following script to easy turn on/off webcam:

    #!/bin/bash

    if [ "$1" == "on" ]; then
            modprobe uvcvideo
    fi

    if [ "$1" == "off" ]; then
            modprobe -r uvcvideo
    fi

    if [ "$1" == "show" ]; then
            mplayer tv://
    fi

    if [ "$1" == "" ]; then

            if [ "`lsmod | grep uvcvideo`" == "" ]; then
                    echo "cam status: off";
            else
                    echo "cam status: on";
            fi
    fi

To turn on:

    > sudo cam on

To turn off:

    > sudo cam off

To check status:

    > cam
    cam status: off

To start mplayer showing the webcam:

    > cam show
