• Recently multitouch detection on track pad sucks.

    In the last week or two the multitouch detection on my track pad has sucked. Ever since I first installed Antergos it has worked wonderfully but now it’s spotty at best and I’m not sure why or how to fix it.

    Laptop - lenovo y-50
    using libinput with nothing else on top
    the only gestures I really need is two finger scrolling, two finger right click, three finger middle click, and pinch zooming.

    is there something I should install on top of libinput for help with this?

    To clarify by spotty meaning they do work, but I’ve got a bout a 70% chance of it not recognizing that I’m using more than one finger.

  • what says:

    demsg | grep elantech


  • this is my dmesg | grep elantech

    [ 19.436428] psmouse serio1: elantech: assuming hardware version 4 (with firmware version 0x495f01)
    [ 19.446612] psmouse serio1: elantech: Synaptics capabilities query result 0x70, 0x15, 0x0e.

  • The holy ArchWiki says:
    If a touchpad device is not detected and shown as a device at all, a possible solution might be using one or more of these kernel parameters:
    i8042.noloop i8042.nomux i8042.nopnp i8042.reset

    sudo nano /etc/default/grub

    change the line :



    GRUB_CMDLINE_LINUX_DEFAULT="i8042.notimeout i8042.nomux quiet"
    sudo grub-mkconfig -o /boot/grub/grub.cfg
    sudo grub-install /dev/sdX

    X change to your value
