Synaptics Touchpad, double finger scroll and tap-to-click

I've recently lost tap-to-click functionality on my synaptics touchpad, I have no idea why because I haven't changed anything recently.

Here's my related xorg.conf file:

Section "InputDevice"
   Identifier  "SynapticsTouchpad"
   Driver      "synaptics"
   Option      "AlwaysCore"        "true"  # send events to CorePointer                                                                                        
   Option      "Device"            "/dev/psaux"
   Option      "Protocol"          "auto-dev"
   Option      "SHMConfig"         "false" # configurable at runtime? security risk                                                                            
   Option      "MaxTapTime"        "180"   # max time in ms for detecting tap                                                                                  
   Option      "VertTwoFingerScroll"   "true"  # vertical scroll anywhere with two fingers                                                                     
   Option      "HorizTwoFingerScroll"  "true"  # horizontal scroll anywhere with two fingers                                                                   
   Option      "EmulateTwoFingerMinZ"  "120"
   Option      "CircularScrolling"          "on"
   Option      "CircScrollTrigger"          "3"
   Option      "TapButton1"                 "1"
   Option      "TapButton2"                 "1"
EndSection

I'm not sure if I have hotplugging installed so I copied my 11-x11-synaptics.fdi file anyway and edited it:

<?xml version="1.0" encoding="ISO-8859-1"?>

        <!-- Arbitrary options can be passed to the driver using

        <!-- EXAMPLES:

    <merge key="input.x11_options.SHMConfig" type="string">true</merge>

    Maximum movement of the finger for detecting a tap
    <merge key="input.x11_options.MaxTapMove" type="string">2000</merge>

    Enable vertical scrolling when dragging along the right edge

    Enable vertical scrolling when dragging with two fingers anywhere on the touchpad

    Enable horizontal scrolling when dragging with two fingers anywhere on the touchpad
    <merge key="input.x11_options.HorizTwoFingerScroll" type="string">true</merge>

    If on, circular scrolling is used
    <merge key="input.x11_options.CircularScrolling" type="string">true</merge>

    For other possible options, check CONFIGURATION DETAILS in synaptics man page
        -->
    </match>
  </device>
</deviceinfo>

You use gnome? Check mouse settings

Yup, that seems to be the problem. Is there a way I can get the xorg.conf to override the gnome mouse settings?

Re: Synaptics Touchpad, double finger scroll and tap-to-click

I have the same problem, my workaround is setting the options with synclient executed automatically on login.
Im quite annoyed though that gnome just overrides settings done in xorg and hal policies, can anyone tell where to look for gnomes information storage?

Re: Synaptics Touchpad, double finger scroll and tap-to-click

In order to re-enable multi touch just open up gconf-editor and navigate to

desktop/gnome/peripherals/touchpad

Change the value of scroll_method to 2.
