how to fix the screen sharing ??

Hello Hitesh, Thank you for reaching out to the Microsoft Community. My name is Seun and I'm happy to help. Here are the steps to resolve this issue: I'm sorry to hear that you're having trouble with screen sharing in Microsoft Teams on your Ubuntu platform. This issue might be due to the display protocol used by Ubuntu. Recent versions of Ubuntu use a protocol called Wayland, which may not be fully supported by Microsoft Teams. I pulled the following inforamtion from https://learn.microsoft.com/answers/questions/829747/how-to-enable-screen-sharing-in-ms-teams-desktop-o?orderBy=Newest. : "1. Open a terminal. 2. Type the following command to edit the GDM3 configuration file: `sudoedit /etc/gdm3/custom.conf` 3. In the file, find the line that says `#WaylandEnable=false` and uncomment it (remove the `#` at the beginning). The line should now read `WaylandEnable=false`. 4. Save your changes and close the file. 5. Restart your device or restart GDM3 by typing the following command in the terminal: `systemctl restart gdm3` After the restart, this should resolve the issues with Microsoft Teams screen sharing." Please note that this solution assumes GDM3 is your default display manager. If you're using a different display manager, the steps might be slightly different. I hope this information helps, if you require further help or information, please let me know. Best Regards, Seun
