Ubuntu 22.04 suddenly goes Black Screen after apt upgrade

I have similar issue for my ubuntu: Ubuntu suddenly goes Black Screen

The system can normally boot into the GUI and I can use it for few hours. It just suddenly went black screen and it happened couple of times since my last update/upgrade. However, I tried take control this morning by pressing Ctrl+Alt+F2 and I found login prompt pop up. So, it is not a total system crash. It seems like some desktop package crash.

Does anyone know how to do inspection and fix it? Thanks.

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.
