Issue: On Ubuntu 20, when I tried to share my screen on Microsoft Teams (MS Teams), I didn't get the option to pick a window at all. Basically, we do "Share Screen" and then pick a window we want to share. Here, I could click on "Share Screen", but there are no windows to share. Solution: This is because of Wayland environment. You have to use another environment and it will work fine. To choose another environment, come over to your login screen and check for that small wheel at the bottom right. You can see "Ubuntu" and "Wayland". Choose "Ubuntu" and you are done. This solution will also help if you have a case where you can share the screen but end up with a black screen and visible mouse pointer. Happy Meetings!
