[SOLVED] Touchpad Synaptics -- is xorg.conf preferred over udev?

Reading the Touchpad Synaptics wiki it states that "Configuration for the touchpad should done by an Xorg server configuration file. As of Xorg server 1.8 configuration by HAL policy is deprecated." Does this also apply to udev?

My two week old install doesn't currently have an xorg.conf file is it possible to just add the relevant touchpad entry to one?

Thanks.

In the past, we used xorg.conf for everything. Then we had HAL, so we wrote a little HAL policy. Now we write an udev rule.

The wiki might be confusable. You can either use an xorg.conf or HAL/udev.  Since Xorg 1.8 doesn't use HAL anymore, use either a xorg.conf or udev.

It's explained in the wiki how to do it with udev:

synaptics wiki page

udev

Same as HAL, but settings go in /etc/X11/xorg.conf.d/10-synaptics.conf instead of /etc/hal/fdi/policy/11-x11-synaptics.fdi. See http://andreascarpino.it/2010/04/xorg-1 … iguration/.

If you have no good reason to use xorg.conf, try to get used to the udev rules.

Yes. However, the wiki is outdated. The section is not InputDevice anymore, but InputClass. It should look like this:

Section "InputClass"
    Identifier    "touchpad"
    MatchIsTouchpad    "on"
    Driver        "synaptics"
    Option        "TapButton1"        "1"
EndSection

You can also simply modify /etc/X11/xorg.conf.d/10-synaptics.conf
