Debian 10.5 on GNOME two-finger scrolling keeps disabling.

[adowson]

I’m having a weird issue with GNOME where I have to keep re-enabling two-finger scrolling. As a temporary resolution I can run “sudo modprobe -r psmouse && sudo modprobe psmouse”. However, once the laptop suspends/resumes, two-finger scrolling completely stops working until I run the previous command again. Sometimes two-finger scrolling does work, but it requires heavy pressure on the trackpad unless I run the above modprobe commands.

To enable two-finger scrolling through the GUI I have to click on the switch twice before it enables, all other settings switches require one click which is odd. As soon as I switch out of that setting window and return, two-finger scrolling is disabled. No amount of re-enabling will keep it permanantly enabled.

My next step was to try manually re-enable it by running “gsettings set org.gnome.desktop.peripherals.touchpad two-finger-scrolling-enabled true” which has no effect and two-finger scrolling still appears as disabled in the GUI.

I have also tried modifying “/usr/share/X11/xorg.conf.d/40-libinput.conf” by adding “Option "ScrollMethod" "twofinger"” but even after a reboot this doesn’t change anything. See:

Code: Select all

Section "InputClass"
        Identifier "libinput touchpad catchall"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Driver "libinput"
        Option "Tapping" "On"
        Option "ScrollMethod" "twofinger"
EndSection

I’m stumped? I’m guessing that this is a problem with GNOME since I’ve seen some mention of similar-ish issues online but none of their solutions have worked for me. Any ideas? Device is a Thinkpad x250.

I'm guessing this is a problem with the user since I'm running Debian 10.5 with GNOME and two-finger scrolling is maintained between reboots for me.

Please post the output of
