Dell XPS 13 Plus 9320: Ubuntu and touchpad issue

ua flag

I just bought a new XPS 13 plus 9320. Installed Ubuntu 22.04 LTS on it. It works well except for one thing. When I plug in the charger, the touchpad becomes laggy with a few milliseconds (very annoying). It's hard to be precise with the touchpad. Also, the cursor jumps randomly sometimes.

If I do not plug in the charger, it works as expected.

I've tested it on Ubuntu 20.04 as well, and there's the same problem there.

I've tried to search around for a fix, but I've not found anything online. Could it be a firmware problem or is it something wrong with the hardware?

The name of the touchpad in xinput is VEN_04F3:00 04F3:31D1 Touchpad

The touchpad issue impacts many Dell XPS laptops, Dell forum thread here.
First thing to do is update the touchpad firmware, the link above is for an UK model update from 30 Sep-2022.
You could boot into Windows to have the laptop updated.

I sit in a Tesla and translated this thread with Ai:

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.
