Hello,
Tried a fresh install of Ubuntu 20.04.2 and problem is the same even I haven't
activated fractional scaling.
The touchscreen is working good on live iso.
It's also working good on GDM before a session is opened.
Hope you can fix this bug.
Best regards.

I tried on "Ubuntu on Wayland" session and the problem is the same.
journalctl -b0 > journal_on_wayland.txt

the problem
journalctl -b0 > journal.txt
when touchscreen is not working

* Does logging into 'Ubuntu on Wayland' fix the problem?
Also when the problem is happening please run:
