Mouse and keyboard input lag / stutter / jumping on Ubuntu 23.04

fr flag

Working on a clean install of Ubuntu 23.04, fully updated. Most of the time, they keyboard and mouse are unusable: the mouse jumps / lags / stutters and the keyboard input takes a few ms to display on screen. I've been through a multitude of posts although none seem to help.

If it helps,

  • the devices are connected over bluetooth.
  • Models Logitech MX Mechanical & MX Master 3S.
  • Interestingly, the mousepad on the laptop is silky smooth at all times.
  • Switching to Xorg makes no difference.

The units are fine: I have two other machines (22.10 and 22.04 LTS) both work fine. Any suggestions?

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.
