  1. title Synaptics Touchpad

On most laptops, a touchpad is the input device used as a substitute for a computer mouse. The term "Synaptics Touchpad" should not be confused with "Synaptic", Ubuntu's Package Manager. The touchpad will be detected and configured during the Ubuntu installation. However, in Ubuntu 6.06 LTS (Dapper Drake) and Ubuntu 6.10 (Edgy Eft) touchpads may not be detected, in which case scrolling will not work. See the troubleshooting Troubleshooting section. Anchor(gui)

Configuration with a Graphical Interface

This sections describes how to install a GUI configuration tool for your Synaptics touchpad which integrates into your desktop environment. Other methods of configuring the touchpad include using synclient synclient on the command line, or by adding xconfig options directly to the X server configuration file. Anchor(gsynaptics)

Ubuntu

  • Enable SHMConfig in the X server configuration file as described in the section shmconfig Enabling SHMConfig.
  • For a preference tool which integrates into the GNOME Desktop environment, install the gsynaptics package from the universe repository. For help with installing packages see InstallingSoftware.

After installation, gsynaptics can be found under System > Preferences > Touchpad. Anchor(ksynaptics)

Kubuntu

  • Enable SHMConfig in the X server configuration file as described in the section shmconfig Enabling SHMConfig.
  • For a preference tool which integrates into the KDE desktop environment, install the ksynaptics package from the universe repository. For help with installing packages see InstallingSoftware.

After installation, ksynaptics can be found in the KDE Control Center. Anchor(qsynaptics)

Xubuntu and others

  • Enable SHMConfig in the X server configuration file as described in the section shmconfig Enabling SHMConfig.
  • For users of Xfce or anything else besides GNOME or KDE, install the qsynaptics package from the universe repository. For help with installing packages see InstallingSoftware.

Anchor(syndaemon)

Disabling the Touchpad Temporarily While Typing

To avoid accidental mouse movement while typing, syndaemon can be used to monitor the keyboard activity and disable the touchpad for a period of time after the last keystroke. First enable SHMConfig in the X server configuration file as described in the section shmconfig Enabling SHMConfig. The following commands should be typed in a terminal. The -d option causes syndaemon to run in the background, so the terminal can be closed after executing the command. 

syndaemon -d

The -t option causes syndaemon to only disable tapping and scrolling, not mouse movements: 

syndaemon -d -t

By default syndaemon disables the touchpad for 2 seconds after the last keyboard activity. To specify a different timeout, use the -i option. For example, a timeout of 1 second: 

syndaemon -d -i 1

To make syndaemon start up each time you login, add the desired command to the list of Startup Programs in System > Preferences > Sessions. See AddingProgramToSessionStartup. Anchor(shmconfig)

Enabling SHMConfig

In order for tools such as synclient synclient, syndaemon syndaemon, gsynaptics gsynaptics, ksynaptics ksynaptics, and qsynaptics qsynaptics to work, they need access to the synaptics touchpad driver shared memory. This is done by enabling SHMConfig "on" in the X server Synaptics Touchpad configuration. With this enabled, these tools can modify the run-time configuration of the touchpad input driver without restarting the X server. /!\ Note the warning from the man page for synclient: 

WARNING: This is not secure if you are in an untrusted multiuser
environment. All local users can change the parameters at any time.

If this is an issue for you, the touchpad can be configured without enabling SHMConfig by placing the desired options in the X server configuration file and restarting the X server. See xconfig Configuration with the X Server Configuration file. In a terminal type: 

gksudo gedit /etc/X11/xorg.conf

Find the "Input``Device" section for the touchpad: 

Section "InputDevice"
	Identifier	"Synaptics Touchpad"
	Driver		"synaptics"
	Option		"SendCoreEvents"	"true"
	Option		"Device"	"/dev/psaux"
	Option		"Protocol"	"auto-dev"
	Option		"HorizScrollDelta"	"0"
EndSection

If this section is not present, see xinputdevice Adding a Synaptics Touchpad to the X Server Configuration. Add the following line to this section: 

	Option		"SHMConfig"		"on"

The result should look like this: 

Section "InputDevice"
	Identifier	"Synaptics Touchpad"
	Driver		"synaptics"
	Option		"SendCoreEvents"	"true"
	Option		"Device"	"/dev/psaux"
	Option		"Protocol"	"auto-dev"
	Option		"HorizScrollDelta"	"0"
	Option		"SHMConfig"		"on"
EndSection

To enable the changes log out of your desktop environment, and restart the X server by typing Ctrl + Alt + Backspace. Anchor(synclient)

Configuration with synclient

synclient can be used to adjust touchpad settings from the command line. This will work even if a gui GUI Preference tool is installed. Enable SHMConfig in the X server configuration file as described in the section shmconfig Enabling SHMConfig. List all settings: 

synclient -l

Examples

Turn touchpad off: 

synclient TouchpadOff=1

Turn touchpad on: 

synclient TouchpadOff=0

Anchor(xconfig)

Configuration with the X Server Configuration file

The options that are shown by the command synclient -l (synclient see above) may also be added directly to the touchpad "Input``Device" section in /etc/X11/xorg.conf. In this case shmconfig SHMConfig does not need to be enabled. For example, to turn the touchpad off, add the line: 

	Option		"TouchpadOff"		"1"

The result will look like this: 

Section "InputDevice"
	Identifier	"Synaptics Touchpad"
	Driver		"synaptics"
	Option		"SendCoreEvents"	"true"
	Option		"Device"	"/dev/psaux"
	Option		"Protocol"	"auto-dev"
	Option		"HorizScrollDelta"	"0"
	Option		"SHMConfig"		"off"
	Option		"TouchpadOff"		"1"
EndSection

Anchor(troubleshooting)

Troubleshooting

Determine Whether a Touchpad Is Configured

To check if a touchpad is configured, open a terminal and check your /etc/X11/xorg.conf file by typing the following: 

grep Iden /etc/X11/xorg.conf

If one of the lines is: 

	Identifier	"Synaptics Touchpad"

then you have a Synaptics Touchpad configured. If not, see xinputdevice Adding a Synaptics Touchpad to the X Server Configuration. Anchor(xinputdevice)

Adding a Synaptics Touchpad to the X Server Configuration

To add support for a touchpad which was not detected the xorg.conf file will need to be edited. In a terminal type: 

gksudo gedit /etc/X11/xorg.conf

After the lines: 

Section "InputDevice"
	Identifier	"Configured Mouse"
	Driver		"mouse"
	Option		"CorePointer"
	Option		"Device"		"/dev/input/mice"
	Option		"Protocol"		"ExplorerPS/2"
	Option		"ZAxisMapping"		"4 5"
	Option		"Emulate3Buttons"	"true"
EndSection

add the following: 

Section "InputDevice"
	Identifier	"Synaptics Touchpad"
	Driver		"synaptics"
	Option		"SendCoreEvents"	"true"
	Option		"Device"	"/dev/psaux"
	Option		"Protocol"	"auto-dev"
	Option		"HorizScrollDelta"	"0"
EndSection

Next, find the "Server``Layout" section near the bottom: 

Section "ServerLayout"
	Identifier	"Default Layout"
	Screen		"Default Screen"
	InputDevice	"Generic Keyboard"
	InputDevice	"Configured Mouse"
	InputDevice     "stylus" "SendCoreEvents"
	InputDevice     "cursor" "SendCoreEvents"
	InputDevice     "eraser" "SendCoreEvents"
EndSection

Add the following line: 

	Inputdevice	"Synaptics Touchpad"

The result should look like this: 

Section "ServerLayout"
	Identifier	"Default Layout"
	Screen		"Default Screen"
	Inputdevice	"Generic Keyboard"
	Inputdevice	"Configured Mouse"
	Inputdevice	"stylus"	"SendCoreEvents"
	Inputdevice	"cursor"	"SendCoreEvents"
	Inputdevice	"eraser"	"SendCoreEvents"
	Inputdevice	"Synaptics Touchpad"
EndSection

To enable the changes log out of your desktop environment, and restart the X server by typing Ctrl + Alt + Backspace.
