I install an ubuntu 21.10 on my Dell XPS 9510.

When I was in video call with google meet in google chrome sometimes in I have a black screen, but my colleagues always see and hear me.

I tried with wayland and x11 and had same issue.

Here my setup:

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.
