• strange behaviour of trackpad on Dell XPS13

    Dell xps13 9310 Mageia 9

    My trackpad is misbehaving. I have it set up so that single finger on
    trackpad is supposed to move cursor, two fingers is supposed to do
    vertical scroll. Unfortunately, often single finger suddenly does
    vertical scroll. If I double tap hard it will behave itself and single
    finger will again do cursor movement. This gets really annoying. I have
    no idea what is doing that. Any suggestions?

    Are you using the Plasma desktop?

    FWIW, after a plasma-workspace update a while back, I discovered that
    the touchpad on my HP Probook 6550b was behaving differently, mostly
    with regard to scrolling as I recall. In System Settings, under
    Workspace Behavior/General Behavior, I found a setting for something
    called "Touch Mode." Changing that from "never enabled" to "always
    enabled" restored normal touchpad scrolling. It also enlarged parts of
    the user interface, like the bar at the top of a window, but I soon got
    used to that.

    My Probook was originally designed as a Windows 7 computer. My newer HP Pavilion, originally a Windows 8 computer, doesn't have that setting. My
    guess is that The Friendly Folks at KDE are trying to simulate Windows Gestures on older machines, not needed on newer machines because it's
    somehow built-in, but I have nothing to confirm that.

    As always, YMMV.

    My memory is faulty - must be getting old. It's been a while since I
    actually looked at these settings on each, and the difference between
    the two laptops is not as I described above.

    On the Probook, several touchpad settings, including two-finger
    scrolling, aren't available unless Touch Mode is enabled. They are there
    in System Settings/Input Devices/Touchpad, but some are grayed out.

    On the Pavilion, Touch Mode IS there to enable/disable, but those
    settings are available if Touch Mode is enabled or not.

    I have no idea why. I can only speculate - very different hardware, very different BIOS.
