XRDP shows black screen after logout

az flag

I'm using Ubuntu 18.04.5 LTS. I installed xrdp but getting the black screen error even after I logged out from remote computer physically. (This happens even though I'm not logged into the device anymore.)

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.
