People rarely move their fingers perfectly vretical or horizontal, not to mention the hand is already aligned diagonally touching the lower edge of the notebook. Both Microsoft and Apple already thought of that.
Accidental diagonal two-finger scrolling should be restricted the same way it is in Windows and OSX. It detects the main direction of your movement: e.g. 70% vertical and 30% horizontal and ignores that 30%. The system should not completely disable diagonal scrolling, but allow the user setting that threshold: 30% or something else. Mac also ignores two finger movement (in one direction) if the fingers are too apart - should be configured as well. And (very annoying Linux "feature") both OSX and Windows ignore the second finger (e.g. in the corner of the trackpad) if it is not moving. It is very natural to rest your left index finger there ready to press/tap while moving the right one to position the cursor. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-input-synaptics in Ubuntu. https://bugs.launchpad.net/bugs/876447 Title: Two-finger scrolling scrolls horizontally and vertically simultaneously Status in xf86-input-synaptics: In Progress Status in “xserver-xorg-input-synaptics” package in Ubuntu: Triaged Bug description: Ubuntu 11.04, Ubuntu 11.10 When "Two-finger scrolling" and "Enable horizontal scrolling" are checked in the Touchpad settings, pushing two fingers up and down scrolls vertically, and pushing two fingers left and right scrolls horizontally. This is a good thing. What is not a good thing is scrolling horizontally while I'm in the middle of scrolling vertically, or scrolling vertically while I'm in the middle of scrolling vertically. That is invariably a mistake, and causes annoying wobbling. https://launchpadlibrarian.net/82846315/out.ogv This could easily be fixed by ignoring any horizontal movement during a two-finger swipe if started out vertical, and ignoring any vertical movement during a two-finger swipe if it started out horizontal.
