Touchpad

Circular scrolling

Device has relatively small round-shape touchpad, so ability to configure circular scrolling is important for usability (since touchpad ares is too small for gestures). As of 06/27/2020, libinput does not have support for circular scrolling, which means you cannot get cirtular scrolling in Wayland. Under Xorg with xf86-input-synaptics installed circular scrolling works fine with following configuration section

/etc/X11/xorg.conf.d/70-synaptics.conf

Section "InputClass"
        Identifier "touchpad catchall"
        Driver "synaptics"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Option "TapButton1" "1"
        Option "TapButton2" "3"
        Option "TapButton3" "2"
        Option "CircularScrolling" "on"
        Option "CircScrollTrigger" "0"
        Option "CircularPad" "on"
        Option "LeftEdge" "80"
        Option "RightEdge" "450"
        Option "TopEdge" "80"
        Option "BottomEdge" "450"
EndSection

After saving the file, restart Xorg.

Fix touchpad delays after system wake from sleep

Touchpad starts to behave badly and introduce pointer moving delays after system wake up from sleep. To address the issue, i2c_hid kernel module must be unloaded and loaded back again. Following script does the job:

/lib/systemd/system-sleep/fix-touchpad.sh

#!/bin/sh

if [ "$1" = 'post' ]; then
    echo "Reloading i2c_hid module to fix touchpad behavior"
    modprobe -r i2c_hid && modprobe i2c_hid
fi

Audio

Requires sof-firmware to fully function.
