Today I installed the Ubuntu 10.10 release on my Desktop PC. I was running Ubuntu 10.04 LTS with an Apple Magic Trackpad and everything was working fine. After today's fresh installation of Ubuntu 10.10, I don't see my Apple Magic Trackpad's multitouch working. Two-finger scrolling and three-finger third mouse button clicking are completely broken.

Has anyone else experienced a similar issue? Has anyone had success with Ubuntu 10.10 and an Apple Magic TrackPad?

Please help me to fix this issue. Your help is highly appreciated...

Note: If you have a MacBook, don't look here. This is about the Magic Trackpad only. Different drivers are needed: askubuntu.com/questions/9460/… or askubuntu.com/questions/24235/… –  A Student at a University Feb 14 '11 at 6:59

So far I've only had success in 10.10 by using the "synaptics" driver.

Put the following in your xorg.conf:

Section "InputClass"
        Identifier "multitouch touchpad"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Driver "synaptics"
EndSection

Once that's done, you should be able to tweak the cursor speed, scrolling speed and other parameters with gpointing-device-settings. Not sure if it's legacy now, but you may need

Option "SHMConfig" "True"

in the above section for that as well.

Thanks alot. It worked. However, I was having one finger touch for left click and two finger touch for right click and 3 finger touch for middle click. Now, 3 finger click as expected... Single finger touch changed to right click and two finger touch changed to left click. How can change this ?. Thanks in advance... –  Sureshkannan Duraisamy Oct 11 '10 at 17:31
    
I'm unable to reproduce that behavior. You may want to ask for assistance in the #ubuntu-touch channel on Freenode. –  mgunes Oct 11 '10 at 19:43
    
Thanks. Is your trackpad single touch mapped to left click ?. (for right hand mouse). I didn't had Option SHMConfig "True". Is that makes any difference ?. ubuntu-snippets.blogspot.com/2009/03/… –  Sureshkannan Duraisamy Oct 11 '10 at 22:49
    
Yes, it's left click; try adding that option. –  mgunes Oct 12 '10 at 0:41

With multiple monitors and ATI eyefinity (3 screens 5760x1080 px) I had a problem with the vertical and horizontal movement speed and acceleration of the mouse pointer with the Apple Magic trackpad in Ubuntu 11.04. (I use the ATI propriety FGLRX drivers)

Also i wanted to simulate the fast flick-to-scroll behavior with two fingers as in OSX.

My settings for the Magic trackpad in /etc/X11/xorg.conf

Section "InputClass"      
    Identifier      "Apple Magic Trackpad"
    MatchIsTouchpad "on"
    MatchUSBID      "05ac:030e"
    Driver          "synaptics"
    Option          "VertScrollDelta"  "50"
    Option          "HorizScrollDelta" "50"
    Option          "MinSpeed"         "0.6"
    Option          "MaxSpeed"         "1.3" 
    Option          "AccelFactor"      "0.08"
    # these two options are for multiple monitors 3:1 ratio.  
    Option          "VertResolution"   "1"
    Option          "HorizResolution"  "3"
EndSection
