Different Thinkpad, similar problem?
I considered other patch hacks, but I’ve been down that road too many times before, and I’d like to avoid that.
My OP: Touchpad not working on Thinkpad X1 Extreme gen 3
I have come to the conclusion that I have to switch back to X11 from Wayland.
(I still think udev is causing this, but I’m unsure how to fix it.)
