    When scrolling with the touchpad, either with 2 finger scrolling or side scrolling, is there a way to turn off the acceleration? By acceleration I mean when you move fast, it scrolls a lot and when you move slowly, it scrolls very little.

    I don't mind acceleration in general but the windows touchpad drivers seem so unrefined. Heck even the built in drivers on ubuntu 11.04 works much better and more fluidly for 2 finger scrolling.

    I'm using a T420 btw.

    Nope. Surprised to hear that the ubuntu drivers are better, they must have stolen some apple code?!? :p

    I assume you've updated to the latest Lenovo-released UltraNav drivers? There have been numerous tweaks over the versions.

    It has a checkbox for "Start with Windows".

    For reference, here're my settings for the W520 touchpad on 1920x1080 at 100dpi, calibrated for Firefox 10. YMMV
    Code:
    Windows Registry Editor Version 5.00
    
    [HKEY_CURRENT_USER\Software\TwoFingerScroll]
    "scroll"=dword:00000001
    "scrollLinearEdge"=dword:00000001
    "scrollSpeed"=dword:0000001c
    "scrollAccEnabled"=dword:00000001
    "scrollAcc"=dword:00000047
    "scrollMode"=dword:00000001

    Yeah I link to that every time broken touchpad scrolling is mentioned under Windows. My theory is that Synaptics is limited by Apple patents on Windows touchpad algorithms.

    It does not support horizontal scrolling though.
