I try to enable one finger scrolling in firefox ( it's more comfortable to scroll like that with a touchscreen). The default fedora version of firefox and chromium work like that.

I tried to launch firefox with the option MOZ_USE_XINPUT2=1 but it doesn't work.. Can you help me ??

  • It would help a little if you explain how you are trying to use MOZ_USE_XINPUT2=1, as in where did you place this command? – Charles Green Mar 02 '19 at 14:43

I had similar issues with the HP Pavilion x360. I found that MOZ_USE_XINPUT2=1 only works in Wayland, not Xorg. Furthermore, to make it a permanent solution I needed to follow these steps:

  1. open about:config in firefox to set dom.w3c_touch_events.enabled=1 (default is 2).

  2. edit /etc/security/pam_env.conf and add MOZ_USE_XINPUT2 DEFAULT=1

  3. reboot and restart firefox

I just might have the solution for you.

I was facing the exact same issue with Firefox where I could only scroll with two-fingers and single finger selected text.

After a lot of searching I found this Gentoo Wacom page mentioning that the Wacom driver has gesture emulation that causes a problem with Firefox and my Thinkpad X1 Yoga has a Wacom touchscreen.

The fix is to turn off the Wacom gesture setting by creating the following file:

/etc/X11/xorg.conf.d/50-wacom.conf

With this configuration:

Section "InputClass"
    Identifier "Wacom class"
    MatchProduct "Wacom|WACOM|Hanwang|PTK-540WL|ISDv4|ISD-V4|ISDV4"
    MatchDevicePath "/dev/input/event*"

    Driver "wacom"
    Option "Gesture" "off"
EndSection

Resart and enjoy :)

    Any idea if this can be tweaked to work for the stylus as well - it's still selecting text instead of scrolling? – kat Dec 06 '19 at 20:19

    So a bit of searching didn't turn up anything using wacom driver but found mention of [easystroke]https://github.com/thjaeger/easystroke/wiki) to map pen button to enable scrolling in browser etc.

found a solution based on the wacom config file Cas mentioned, whose solution ultimately didnt work for me on my yoga 7. however, based on this i found, in the KDE system control panel, under input devices the section graphic tablets. there is a register card touch with a checkbox enable gestures which is activated by default. after disabling it, gestures worked again in firefox. seems they enabled it from 21.10 to 22.04. and yes, as also mentioned by Cas, when this checkbox remains enabled, i have to scroll with two fingers in firefox. i didnt know that.
