    To be clear, using the above is turning on an emulated "multitouch", rather than using the trackpad's built-in functionality.

    The command 'synclient -m 100' will show the current state of the synaptics trackpad, the "f" column is the no. of fingers detected. For me, with a fresh 10.10 install on a Thinkpad Edge 13, it's only ever 1 (or 0), despite the trackpad hardware supporting multi-touch (xinput list reports a "SynPS/2 Synaptics TouchPad").

    Apparently true "multitouch" support is a work in progress (e.g. bug/308191).

    Re: Ubuntu 10.10 two-finger scrolling doesn't work

    Hello,

    I am currently running on an HP G60 and have been trying to enable synclient multiple finger gestures on my trackpad using synclient.

    What's happening is that when I execute my little script MANUALLY on startup through terminal or run command, all options enable themselves through the regular "synclient blablabla=xyz/0/1"...

    Now the thing is that for some reason, When I try to automate the script launch (rc.local, converting the script to execute within /usr/bin or calling the commands with a ; separating them, I only get the standard two finger emulation rather then all of the ones listed below:

    ----
    #!/bin/bash
    synclient TapButton1=1
    synclient TapButton2=2
    synclient HorizTwoFingerScroll=1
    synclient VertTwoFingerScroll=1
    synclient EmulateTwoFingerMinW=5
    synclient EmulateTwoFingerMinZ=10
    ----

    any ideas on how to make my system understand i need to run these.. ALL OF THEM!?

    Thanks..

    Ptosiani's solution, works great. I now have basic two finger scrolling. Thanks!

    Hey there Gandaroth,

    his solution does not help when using opensource display driver as dkms isn't registered through X, thus no xorg.conf file to add or edit.

    the point is that when I run my little script it works (only manually), if i set it as startup (full script, or one script per command) i only get two finger click emulation for mouse right-click.. rather than the whole thing)

    is the any way to get the system to emulate manual script input on startup run?

    I see what you mean. I usually don't power off often, so I didn't notice it at at first. Although my setup may be different, but I'm having problem with it also. It will work when I manually run it, but when I set it to run automatically I will randomly get jumpy cursor or no scrolling at all on next boot. I'm not sure if it's cause directly by this, but it may be related.

    Thank the lord for Ptosiani!

    I've been trying to figure this out on my new Dell Adamo.

    I could get it to work on login by running a script, but if I'd shut the lid and it suspended, the settings were lost.

    This appears to work!!!

    1. Install "Pointing Devices"

    2. Open System / Preferences / Pointing Devices and disable Vertical and Horizontal Scrolling.

    3. Open a terminal (ctrl + alt + t) and execute this commands:
    Code:
    synclient HorizTwoFingerScroll=1
    synclient VertTwoFingerScroll=1
    synclient EmulateTwoFingerMinZ=40 
    synclient EmulateTwoFingerMinW=8
    4.Open a terminal (ctrl + alt + t) and execute this commands:
    Code:
    gconf-editor
    5. Navigate and find this key: /desktop/gnome/peripherals/touchpad/scroll_method

    6. Assign the value '2'

    7.Open a terminal (ctrl + alt + t) and execute this commands:
    Code:
    cat /usr/share/X11/xorg.conf.d/50-synaptics.conf
    8. Copy the Identifier name, in my case, it was "Touchpad catchall"
    Code:
    Identifier "touchpad catchall"
    9. Execute this command, as a Super User.
    Code:
    sudo nano /usr/share/X11/xorg.conf.d/50-twofingerscroll.conf
    10. Write this, making sure to put your Identifier.
    Code:
    Section "InputClass"
            Identifier      "touchpad catchall"
            MatchProduct    "SynPS/2 Synaptics TouchPad"
            MatchDevicePath "/dev/input/event*"
            Option          "VertTwoFingerScroll"   "on"
            Option          "EmulateTwoFingerMinW"  "8"
            Option          "EmulateTwoFingerMinZ"  "40"
    EndSection
    And that's all!
    I can verify that these steps work on 11.04 Alpha 1. I'll be posting here with updates on Alpha 2, Alpha 3, Beta and Release candidate.

    10.10 on HP Mini, I even have the same identifier as in the post.

    Re: Ubuntu 10.10 two-finger scrolling doesn't work

    Thanks a lot ptosiani for this post. It works great on my t410 as well. The only issue is that multitouch scrolling is not working after resuming the system from the suspended state.

    Is there a way to launch the script also after resuming?
    Is there another script that is launched after resuming that overrides these settings?

    Thanks a lot

    Have a nice day

    Did anybody else experienced the problem after resuming from the suspend state?

    Cheers
