msi GS66 Stealth 11UH touchpad doesn't work on ubuntu20.04 and 21.04
The same issue, it seems the new version of GS66 equipped with some new hardware, probably need to wait couple of Ubuntu updates
I solved this for upgrading to ubuntu21.10, kernel5.11.0-33. I cannot clean install from USB for any reason, I upgraded from ubuntu21.04. http://cdimage.ubuntu.com/daily-live/current/ FYI, on kernel 5.11.0-31 touchpad didn't work.
