Lenovo Yoga 6 touchscreen stopped working

My Lenovo Yoga 6 13ALC6 touchscreen seems to have stopped working after after a while, I don’t know if this was due to an update or something else. This holds true with both X11 and Wayland.

Strangely enough, even though it doesn’t work when I try using the touchscreen with my finger, using a touch pen still works.

That seems to imply that it may be a hardware level issue. You can try running sudo libinput debug-events and while that is running, touch your touchscreen with your finger and see if it generates an event. If it doesn’t then the touch event isn’t getting to Fedora to process it.

Touching the screen does not generate an event when running libinput debug-events, but moving the touch pen closer to the screen or tapping with it does generate an event.

In that case, it’s happening at the hardware level, in which case you may need to contact Lenovo.
