    No ideas for possible workarounds; for the moment, disabling "click on tap" seems to help (but I can't confirm that it actually prevents the problem from occurring, since I haven't ben using the laptop under ubuntu in the past few days), but it's a bit of a pain.
    I have been experiencing something similar with my previous laptop as well - a Dell XPS M1330 (but the problem occurred somewhat less frequently and seemed to slowly fade away as the years passed - or maybe I just unconsciously learned to avoid those movement that triggered the unwanted clicks, who knows).

    Anyway, if somebody has any idea, I could do some testing.

    Cheers
    This seems to have (largely) fixed it for me:

    Code:
    synclient HorizTwoFingerScroll=0 TapButton1=1 LockedDrags=0 FingerLow=20 FingerHigh=120 VertScrollDelta=18 MaxTapMove=10 SingleTapTimeout=100 MaxTapTime=100 MaxDoubleTapTime=200 RTCornerButton=0 RBCornerButton=0 LTCornerButton=0 PalmDetect=1 PalmMinZ=300 MaxSpeed=4 PalmMinWidth=10 VertEdgeScroll=0 FastTaps=1
    I've also got kernel patches for 2.6.39 which enable AHCI (SATA) mode when not EFI booted and and which enable screen dimming, if anyone is interested.

    MBP 8,3.

    Re: Macbook Pro 8,1 + Maverick

    I am using the multitouch input, and I get:
    synclient HorizTwoFingerScroll=0 TapButton1=1 LockedDrags=0 FingerLow=20 FingerHigh=120 VertScrollDelta=18 MaxTapMove=10 SingleTapTimeout=100 MaxTapTime=100 MaxDoubleTapTime=200 RTCornerButton=0 RBCornerButton=0 LTCornerButton=0 PalmDetect=1 PalmMinZ=300 MaxSpeed=4 PalmMinWidth=10 VertEdgeScroll=0 FastTaps=1
    Couldn't find synaptics properties. No synaptics driver loaded?

    when I try that.

    I am *not* using multitouch. I only really care about two finger right click/swipe to scroll, and that does not require multitouch.

    So what exactly does the multitouch driver provide that the non-multitouch driver can't do?

    Three finger? Pinch to zoom? Not sure.

    Nothing I care about.

    Yes, same issue here with a MBP 8,1. I had to unload the module again and purge the xorg.conf from the multitouch stuff.
    Another problem is that I have no right click and left-click and grabbing/moving a window doesn't work either.

    Re: Macbook Pro 8,1 + Maverick

    Yeah, for me, when using multitouch driver, sensitivity is too high, and mouse randomly locks up (but not the display), and with the non multitouch default driver, i can't seem to click and drag, which I really need, especially when I want to copy and paste or move a window.

    I'm very interested. Can you post the patches somewhere?

    Slightly offtopic:

    There's a request to test the new Natty Narwal beta 2 on laptops. This might be a great way to make sure Natty Narwal will run perfectly on the new Macbooks.

    See here for more info:
