Hello all, as per the title description it was allw orking fine until latest days. When I share my full desktop in teams, other people sees a black screen, but sharing a single application works.

I've tried with the web app and it works fine, it's the local installation that is not working.

I've already tried to reinstall Teams and cleared all the cache but issue persist.

Anyone can help me out? it's driving me nuts

Thanks

Carlo

    Hi,

    I have solved this issue by the change of graphical processor linked with Teams application.

    Steps:

    Type Teams in Start

    Right click on Teams -> open file location

    Right Click on Teams Icon -> Set Graphical processor

    Worked for me.

    Ubuntu 20.04, latest linux client (as of 7/31/2020)

    However, I found the web version worked just fine w/o this change.

    Also, web version allows sharing screen of desktop, application, and chrome tab, while desktop version only gives me option to share whole desktop. So web version is even better.

    I have the same problem, but it shows black when i try to show the entire screen of my external monitor (second screen) when i have the display settings to show either this screen only (laptop screen off) or in extend mode. Sharing one application window worked fine, but that can be problematic when i want to jump to a browser. 

    Sharing the laptop screen full works fine but not what I want to do.

    I have a workaround and that is to set both monitors to duplicate. then full screen sharing works. 

    Perhaps some braino on the Microsoft Teams team can solve this problem. GoToMeeting and Zoom both work perfectly with my hardware.

    Based on some Googling I found following solution. (It works for me on Fedora 31, Kernel: 5.7.11-100.fc31.x86_64)

    Steps to resolve the problem:

    1. Turn off teams
    2. Install 'xcompmgr':

    sudo dnf install xcompmgr

    1. Run following command to start teams:

    teams && xcompmgr -c -l0 -t0 -r0 -o.00 &

    More information about 'xcompmgr' can be found here

    I hope this will help someone.

    Best regards.
