Microsoft Teams - Black screen when sharing desktop, works with single application

Question

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

Answer 1

I had the same problem on debian 10 with XMonad window manager and this solution worked perfectly - i.e. removing /usr/share/teams/resources/app.asar.unpacked/node_modules/slimcore/bin/rect-overlay

Answer 2

The 1.3.00.16851 version also isn't working for me. (Linux Mint 19.2, i3 desktop)

The same for me (Debian GNU/Linux bullseye/sid, i3 desktop).

For all Linux users working on a bare window manager (such as, i3, awesome, Window Maker, fluxbox, blackbox, iceWM, and so on) without a composer (like compton), take a look at -> https://docs.microsoft.com/en-us/answers/questions/42095/sharing-screen-not-working-anymore-bug.html

Hello Treawlony1986,

Thanks for your post in Microsoft community. Since you are able to share your screen as single application in Teams desktop, so first of all we suggest you to kindly double verify you have assigned Meeting policy with entire screen sharing mode.

For this:

1. Login with Microsoft Teams Admin center : Users > Search for your user account > check Meeting policy name assigned to you
2. Now Go to Meetings > Meeting policy > search for the meeting policy which was assigned to you and click on edit option to view all settings > go to Content sharing > check screen sharing mode is set as “Entire screen”.

Further based on your post, could you please kindly let us know, when issue occurred, is there any activity performed on your system (such as update Windows, Teams and any other such kind of activity)?

• Kindly share us screenshot or video about your issue, it helps us to identify issue more clearly.
• To narrow down this issue, we request you to kindly run Teams Debug logs and share us the result.

Kindly share above request information via the Private Message.  For your privacy, we will send it to collect further information.

Thanks and regards,
