Below is the hardware and driver summary. It's an Acer with Intel i5. I have 2 identical monitors. Both worked when I did the initial install of Ubuntu (dual boot with Windows). Both show the splash screen with animations, but as soon it gets to the desktop GUI only one screen is live. If I leave the second screen powered the other display flickers every few seconds. Using Settings you can see the OS detects the display briefly then disconnects. If I switch ports the same thing happens in reverse. When I boot into Windows both displays wsork normally.

I don't know what to do. I have tried repair, refreshing the apt repository. The USB image I just made and booted from has the same problem. I am a Linux newb, so give simple steps please. Telling me what to do without an example is no help at all. I did try booting with Xorg. Both screens live at login, the same result at GUI.

I can only assume the answer is give up on Ubuntu and try a different OS.

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.
