Public bug reported:
After using the touchpad for a while, it suddenly believes that I'm
doing a two-finger scroll, when I'm not. It makes the touchpad unusable
: it's not possible to move the mouse anymore, vertical scrolling
happens instead. I could not find an action that reliably gets me out of
this mode (except reboot !).
My workaround for now is to disable two-finger scrolling in "Config /
Devices / Mouse & Touchpad", and enable "Edge scrolling" instead.
I'm using Ubuntu 19.04 (Ubuntu 5.0.0-21.22-generic 5.0.15)
