Comment 9 for bug 1851901

I forgot to add something potentially important - this used to work until a few days ago. I don't know which update exactly broke things, since usually I use a mouse and I simply didn't notice right away. I updated via the software center pop-up so there could be even more delay.

I went back to older kernels and it does not work anymore (5.2.9 and 5.3.0-18 - 5.3.0-22). On 18.04.3 LTS in a live session the touchpad works, while the touchscreen doesn't.
