Tap-to-click sensitivity adjustment on Ubuntu 23.04

cn flag

I'm having about half of my single toGNOMEuchpad taps ("tap-to-click") ignored on Ubuntu 23.04 GNOME. It was working fine on 22.10 on same laptop right before upgrade. I imagine there is a sensitivity adjustment that can be made, although it is not in settings. I've searched around, but cannot find a solution. How can I adjust the tap sensitivity?

Second question: libinput reports tap-to-click is disabled, yet it is enabled in GNOME. settings, so does GNOME interpret tap-to-click in software or some other way?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
