Screensharing not working in the official MS Teams for Linux

Since sometime last week, screensharing in MSTeams for Linux has stopped working.

I'm on Ubuntu 20.04 with the official install of MS Teams. During a call, the screenshare button is visible but doesn't do anything.

Any ideas?

Up to 10 attachments (including images) can be used with a maximum of 3.0 MiB each and 30.0 MiB total.

Actually for me it crashes and restarts the team app again. It was working fine but after recent upgrade activity on ubuntu 20.04 LTS, Teams crashes on screen share.

Web app works fine but on screen share only black screen is available.

May be it will help microsoft guys if they are planning to improve teams on linux.

Problem solved - Administrators have two settings for Guest accounts/users; "Single App" or "Whole Screen" sharing.

It was set to "Single App" which seemed to break screen sharing in Linux Teams entirely. They have now changed to whole screen and it is fixed!

Its still an issue with Ubuntu 20.04 (plasma desktop). The moment i share the Desktop, all i see is a black screen with red border. I had to switch to another terminal (Ctrl-Alt-2) and kill teams. And after that the audio stops working completely. I had to switch to another terminal (Ctrl-Alt-2) again and come back to the original desktop.

I am still facing same issue for Ubuntu 17.10. I can see clearly if someone else is sharing screen but if I try to share screen from my desktop app, it crashes and restarts app with a message "There was a glitch in Teams app". If I try to share screen using web browser, other people can see only black screen with cursor moving.


Please help me in resolving this issue.

Official not supported for Linux :-|

"Außerdem steht die Fensterübertragung Linux-Benutzern nicht zur Verfügung."

Hi Paul!

Does this issue persist all the time?

Are there any error messages when you click screenshare button?

In this case, we recommend you try to clear Teams cache and restart your client to see if it can be fixed.

If there is no luck, you can also try to reinstall Teams client to see if it works for you.

I did a test in my environment (Ubuntu 18.04) and it can share desktop normally, but we cannot see mouse pointer in the screen (it is a known issue). And I will also do a test in Ubuntu 20.04 to see if we can reproduce this issue and give a feedback to you.

Thanks Jimmy and Michael,

Clearing cache doesn't help but I should note that I'm using a guest account to work with a client. Could that cause the issue? I am able to share screens when using my windows PC.

I'll try a reinstall and let you know if that helps.

Nope, that didn't work. I also get the problem using Teams in-browser from Ubuntu 20.04.

A screenshot of the debug attached.

There are problems on Mac now also and this IS supposed to be supported, right?
After I turn on screen sharing the first pane is sent to my recipient and then it is not updated after that. If I try to work with more with screen sharing, the fan turns on full bore and eventually the app just hangs except for chat. (Thanks goodness, I can at least tell my audience that I have to quit Teams and start over.) If I try to turn off screen sharing, it disables my audio for the call. If I repeatedly try to turn off screen sharing and then try to quit Teams (so I can restart) it is hung and will not quit. I have to Force Quit it from the Mac OS.
I tried running it and got this behavior. Then I quit the teams client and restarted it and got the same behavior including hang and lost audio. Then I rebooted the system and started the Teams client again and got the same behavior.

For all who still looking some workaround - check this blog article: https://www.faschingbauer.me/blog/2020/03/ms-teams-on-linux.html
I have Ubuntu 20.04 and the same problem described by author.
First section about "Screen Sharing: X11 Revival" helped me in 100% :)
Cheers!

I have come up with a work around. I'm using Mint 20 cinnamon and am using the official release for regular teams and the unofficial release for when I have to share my screen out. Its a bit of a pain but it works for now. I guess I can always go back to using cisco webex.

Ubuntu 20.04.2 LTS (kernel 5.8.0-44-generic, Wayland is disabled), Microsoft Teams Version 1.4.00.4855,

I had the same problem until I uninstalled the proprietary Nvidia driver. I am currently using the open-source "xserver-xorg-video-nouveau". No more issues with screensharing.
