Lubuntu is a desktop system, meaning it's format for releases is year.month. Ubuntu reserves the year format for snap only products like Ubuntu Core 22, which won't use the Lubuntu desktop being packaged in deb packages (the year format being snap only). Have you disabled the power settings & screensaver? https://manual.lubuntu.me/stable/ Lubuntu also doesn't use GNOME as per many of your commands.

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.
