I'm using ubuntu 20.04 and with Intel UHD Graphics 630, the second monitor is detected but it's all black, does anybody know how to fix this issue?

Is the resolution set to the correct (native) one?

Yes, everything correct, really, didn't understand what happened, something driver related low-level for sure, installed a gpu to solve the problem xD

Same here, with similar GPU: `VGA compatible controller: Intel Corporation UHD Graphics 620 (Whiskey Lake) (rev 02)`. The external monitor is detected as per the output shown by `xrandr` but the output is black. Did you solve it?

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.
