Arch Linux

I noticed that my touchpad does not register tap events anymore. It worked fine a few days ago. Most of the time I use a USB mouse so I did not notice the exact date when it went missing but it worked fine about a week or so ago.

The touchpad settings went missing in Gnome mouse & touchpad settings window to. Is it possible that the touchpad is now registered as a mouse? Which package is responsible for this?
Two-finger scrolling still works.


I checked which packages was upgraded in the last week but I did not see any obvious culprit. I tried to downgrade the kernel and libinput but none of them brought back tap-to-click.

Another user posted about the issue on the BBS with an entirely different type of touchpad (Synaptics vs Elantech): https://bbs.archlinux.org/viewtopic.php?id=214382

Relevant libinput-list-devices output, tap to click is clearly disabled, but what disables it and why?

I've attached a list of packages upgraded in the last 10 days. I'm open to experiment with downgrades but I don't know which package to choose.
