Here is my experience installing the software for a Synaptics touchpad on a Compaq Presario 1690 laptop. Note that this is based on a fresh Debian 3.1 testing install with a 2.6.10 kernel from unstable. Some config file lines may differ from your setup: 1. Using apt or the Synaptic Package Manager (not to be confused with the Synaptics touchpad software), install "xfree86-driver-synaptics". 2. I recommend you install "qsynaptics" as well, or perhaps "ksynaptics" if you prefer; in this case I am using qsynaptics. 3. Open a terminal, "su" to root, and open "/etc/X11/["XF86Config"]-4" in your text editor. 4. Add/replace in the "InputDevice" section for the touchpad the following lines: {{{ Section "InputDevice" Identifier "Synaptics Mouse" Driver "synaptics" Option "Device" "/dev/psaux" Option "Protocol" "auto-dev" Option "LeftEdge" "1700" Option "RightEdge" "5300" Option "TopEdge" "1700" Option "BottomEdge" "4200" Option "FingerLow" "25" Option "FingerHigh" "30" Option "MaxTapTime" "180" Option "MaxTapMove" "220" Option "VertScrollDelta" "100" Option "MinSpeed" "0.09" Option "MaxSpeed" "0.18" Option "AccelFactor" "0.0015" Option "["SHMConfig"]" "on" # Option "Repeater" "/dev/ps2mouse" EndSection }}} 5. Add/replace these lines to the "ServerLayout" section: {{{ Section "ServerLayout" ... InputDevice "ConfiguredMouse" "CorePointer" InputDevice "Generic Mouse" "AlwaysCore" InputDevice "Synaptics Mouse" "AlwaysCore" ... }}} 6. Save the file and reboot. (You may be able to modprobe the synaptics module and restart X instead of rebooting, but this is how I did it.) 7. Log in to your GUI and try running qsynaptics or ksynaptics. If all is well, qsynaptics should report that all is well and you should be able to configure your touchpad. |

On GNOME, go to System -> Preferences -> Mouse, there should be a "Touchpad" tab. On KDE, go to System Settings -> Input Devices, there should be a "Touchpad" tab. For KDE4, you might need to install the '''kde-config-touchpad''' package first (eg: {{{sudo apt-get install kde-config-touchpad}}}). If you can't find a Touchpad or Synaptics tab in your system settings, you may need to edit your "xorg.conf" file. This file has traditionally been a single file named {{{/etc/X11/xorg.conf}}}, but it can also be split up into multiple files in the {{{/etc/X11/xorg.conf.d}}} folder. === In case you don't have an xorg.conf === Create one with the following commands in a terminal: {{{ Xorg :1 -configure }}} Alternatively, reboot the machine in single user mode, and type the following commands: {{{ Xorg -configure }}} Then follow the on-screen instructions. This should give you something to work with. Note: {{{Xorg -configure}}} may not always work, as indicated in Xorg(1). In any case, if you are using Squeeze, read on, as you no longer need a full xorg.conf. === Read the manual === This manual will tell you all the options that are available for the synaptics driver: {{{ man 4 synaptics }}} === Debian wheezy === At start, Xorg reads vendor-supplied configuration commands from directory /usr/share/X11/xorg.conf.d (so says man xorg.conf.d).

The following example shows how to enable tapping and how to configure various other options; you probably won't need everything in it. Comment out any old config for synaptics before replacing it with this new config. (DebPkg:xserver-xorg-input-synaptics (in Squeeze) has tapping disabled by default for touchpads with one or more physical buttons; see {{{/usr/share/doc/xserver-xorg-input-synaptics/NEWS.Debian.gz}}}. For a list of available options, see {{{synclient -l}}} . Not all options are appropriate; for example, Elantech touchpads don't report pressure, and many other touchpads don't support multitouch.) {{{ Section "InputClass" Identifier "Touchpad" # required MatchIsTouchpad "yes" # required Driver "synaptics" # required Option "MinSpeed" "0.5" Option "MaxSpeed" "1.0" Option "AccelFactor" "0.075" Option "TapButton1" "1" Option "TapButton2" "2" # multitouch Option "TapButton3" "3" # multitouch Option "VertTwoFingerScroll" "1" # multitouch Option "HorizTwoFingerScroll" "1" # multitouch Option "VertEdgeScroll" "1" Option "CoastingSpeed" "8" Option "CornerCoasting" "1" Option "CircularScrolling" "1" Option "CircScrollTrigger" "7" Option "EdgeMotionUseAlways" "1" Option "LBCornerButton" "8" # browser "back" btn Option "RBCornerButton" "9" # browser "forward" btn EndSection }}} It is normal for a touchpad to be presented as both a Synaptics device and as an ImPS/2 device.

Determining the type of Touchpad
The following command will tell you whether you have a Synaptics, ALPS or Elantech touchpad:
egrep -i 'synap|alps|etps' /proc/bus/input/devices
(Elantech support was enabled in Linux kernel 2.6.32-4.)
Editing Touchpad settings through a GUI
Some desktop environments such as GNOME and KDE can allow you to adjust settings of your touchpad through a graphical system settings panel.
On GNOME, go to System -> Preferences -> Mouse, there should be a "Touchpad" tab.
On KDE, go to System Settings -> Input Devices, there should be a "Touchpad" tab. For KDE4, you might need to install the kde-config-touchpad package first (eg: sudo apt-get install kde-config-touchpad).
If you can't find a Touchpad or Synaptics tab in your system settings, you may need to edit your "xorg.conf" file. This file has traditionally been a single file named /etc/X11/xorg.conf, but it can also be split up into multiple files in the /etc/X11/xorg.conf.d folder.
In case you don't have an xorg.conf
Create one with the following commands in a terminal:
Xorg :1 -configure
Alternatively, reboot the machine in single user mode, and type the following commands:
Xorg -configure
Then follow the on-screen instructions. This should give you something to work with.
Note: Xorg -configure may not always work, as indicated in Xorg(1). In any case, if you are using Squeeze, read on, as you no longer need a full xorg.conf.
Read the manual
This manual will tell you all the options that are available for the synaptics driver:
man 4 synaptics
Debian wheezy
At start, Xorg reads vendor-supplied configuration commands from directory /usr/share/X11/xorg.conf.d (so says man xorg.conf.d).
If generating xorg.conf fails for you, files there may be useful.
Debian squeeze, kernel 2.6.32-4 and later, Xorg 7.5
You should use a file in /etc/X11/xorg.conf.d, e.g. /etc/X11/xorg.conf.d/synaptics.conf, for configuration (but this will work just as well in a combined /etc/X11/xorg.conf file). /usr/share/X11/xorg.conf.d contains distro-supplied samples which can be copied over (or at least keep an eye on their settings when creating your own configuration). The following example shows how to enable tapping and how to configure various other options; you probably won't need everything in it. Comment out any old config for synaptics before replacing it with this new config.
(xserver-xorg-input-synaptics (in Squeeze) has tapping disabled by default for touchpads with one or more physical buttons; see /usr/share/doc/xserver-xorg-input-synaptics/NEWS.Debian.gz. For a list of available options, see synclient -l . Not all options are appropriate; for example, Elantech touchpads don't report pressure, and many other touchpads don't support multitouch.)
Section "InputClass" Identifier "Touchpad" # required MatchIsTouchpad "yes" # required Driver "synaptics" # required Option "MinSpeed" "0.5" Option "MaxSpeed" "1.0" Option "AccelFactor" "0.075" Option "TapButton1" "1" Option "TapButton2" "2" # multitouch Option "TapButton3" "3" # multitouch Option "VertTwoFingerScroll" "1" # multitouch Option "HorizTwoFingerScroll" "1" # multitouch Option "VertEdgeScroll" "1" Option "CoastingSpeed" "8" Option "CornerCoasting" "1" Option "CircularScrolling" "1" Option "CircScrollTrigger" "7" Option "EdgeMotionUseAlways" "1" Option "LBCornerButton" "8" # browser "back" btn Option "RBCornerButton" "9" # browser "forward" btn EndSection
It is normal for a touchpad to be presented as both a Synaptics device and as an ImPS/2 device. If this is so, then /var/log/Xorg.0.log should show that X has found a touchpad on /dev/input/event6 (for example) and probably also that it has failed to do so on /dev/input/mouse0 (for example). This is fine.
Multitouch
If multitouch doesn't work for you, your hardware may not support it, but you can use the following options to emulate multitouch which allows most of the features to work. Try adding these lines to the Touchpad section (shown above):
Option "EmulateTwoFingerMinZ" "35" Option "EmulateTwoFingerMinW" "8"
You can check which buttons are reported in Xorg.0.log to see if you have multitouch. A touchpad without this capability reports only the usual "left", "right" and "middle" buttons:
$ grep "TouchPad: buttons:" /var/log/Xorg.0.log (II) SynPS/2 Synaptics TouchPad: buttons: left right middle
A touchpad with multitouch reports "double" for two-finger multitouch and "triple" for three-finger multitouch:
$ grep "TouchPad: buttons:" /var/log/Xorg.0.log (II) SynPS/2 Synaptics TouchPad: buttons: left right middle double triple
Debian squeeze, kernel 2.6.30-1, Xorg 7.4
If you are using a generic synaptic touchpad, but it fails to respond to tapping or scrolling actions under a new installation of Squeeze (as in testing), you can run the following two commands to immediately make it work:
modprobe -r psmouse modprobe psmouse proto=imps
To make this change permanent, create a file such as touchpad.conf under /etc/modprobe.d/, and put the following line in it:
options psmouse proto=imps
You do not need to install gsynaptics, synaptic, tpconfig or edit xorg.conf. All you need is passing the kernel options for module psmouse.
Asus eee PC 901
Note, however, that if you DO install the synaptics driver and you are running the "options ps proto-imps" option, that your Elantech touchpad will not be detected as such....it will show up as a mouse of some type. In this case, the symdaemon and synclient programs will not be usable.
Asus F3JC
On an Asus F3JC, most features of its Synaptics touchpad were not automatically detected by Xorg 7.4 although the xorg synaptics driver was already installed.
1. Install the driver, if not already installed
aptitude update aptitude install xserver-xorg-input-synaptics
2. Edit /etc/X11/xorg.conf
Section "Module" Load "synaptics" EndSection
Section "InputDevice" Identifier "Mouse0" Driver "synaptics" Option "Protocol" "auto" Option "Device" "/dev/psaux" Option "Emulate3Buttons" "no" Option "ZAxisMapping" "4 5" Option "TapButton1" "1" Option "SpecialScrollAreaRight" "true" Option "VertEdgeScroll" "true" Option "VertTwoFingerScroll" "true" EndSection
Note: on my Squeeze with Fluxbox, I had to add gsynaptics-init [I used gsynaptics] on my startup list program ~/.fluxbox/startup --?LucaGentile
Debian Lenny, kernel 2.6.21, Xorg 7.3
On a Dell Latitude C610, very little was needed to configure the more advanced features of the touchpad. The touchpad was detected and package xfree86-driver-synaptics was already installed.
1. Edit /etc/X11/xorg.conf Find the section regarding the Touchpad (which is correctly recognised during installation) and add the option SHMConfig "on"
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
2. Restart X: close all unsaved documents, then ctrl-alt-backspace (you could also reboot)
3. install a package to act as a control panel for the touchpad. I used gsynaptics; there are a number of choices, including ksynaptics and qsynaptics.
4. Launch your control panel to finish configuration. The touchpad works as a mouse even before these steps, but with the control panel you can add the functionality of the right edge of the touchpad being a scroll cursor zone (like a mouse scroll wheel).
At this point, the touchpad works, including in firefox/iceweasel.
Read the rest of this page for more tips, which are still relevant to recent kernels.
The syndaemon Helper
syndaemon is able to help with a number of things, including palm-check and such. one possibility for loading this at X startup for all users is to add a separate file in /etc/X11/Xsession.d (i.e. /etc/X11/Xsession.d/98x11-syndaemon)
# This file is sourced by Xsession(5), not executed. # Load settings from ~/.qsynaptics /usr/bin/qsynaptics -r # start synaptics daemon to enable proper communication with touchpad /usr/bin/syndaemon -d -t -k -i 1
This also loads settings from the qsynaptics control panel. This can of course be omitted. If you leave it in, you should make sure all new users have sensible options set by copying a working .qsynaptics to /etc/skel.
