Screen sharing in Ubuntu does not work

When I try to share my screen, I get the following error message: "Your video isn't working. We couldn't access your camera." But the camera/video is working. (My colleagues can see me.)

To Reproduce

1. Try to share your screen.
   
2. The error message will be displayed.
   

Desktop

Additional context
In the browser (Vivaldi) works the Screen Sharing.

@AntoninSlejska it's a problem with snap and the way sandboxing done in it. Can you try flatpak ?

[AntoninSlejska]

@jijojosephk Thanks. I have installed the deb package. It seems to work.

Hi, I have exactly the same problem with latest version (1.4.11).
Mine is installed with the deb package, I'm using Ubuntu 22.04 with gnome 42.9, no Wayland.
It's also working in a Web Browser.

Same here:

• Version: teams-for-linux: 1.4.11
• Distribution: openSUSE Leap 15.4
• DE: Plasma 5.24.4
• X11

It did work with the 1.4.7 or 1.4.8 version I was using before without a problem.
I will try to downgrade and see if I can get it to work.

Same on Manjaro:

• Version: teams-for-linux: 1.14.11
• Distribution: Manjaro Linux
• DE: Plasma desktop 5.27.10 (KDE frameworks 5.113.0-1)
• X11

It worked last week with teams-for-linux: 1.14.10; Today I have upgraded just teams-for-linux, no big global upgrade.

Hi, I'm facing the same problem, teams-for-linux is installed via deb package.

System Info:

• Linux Mint 21.2
• Cinnamon 5.8.4

[dagmoller]

Same here:

Slackware 15.0
KDE Plasma
Version 1.4.10 and 1.4.11 (last working version is 1.4.9) (tar.gz)

[BzSpi]

Was in 1.4.11, reverting to version 1.4.10 make it works 🤷

sudo snap revert teams-for-linux --revision 523

[cyber-duracel]

Confirmed for Debian, since 1.4.11 while 1.4.10 was OK.

[frazzaglia]

Hi, if I try to install 1.4.10 from apt on linux mint I get this error:

E: Version "1.4.10" "teams-for-linux" not found

The command is:
sudo apt-get install teams-for-linux=1.4.10

Thanks.

Hi, if I try to install 1.4.10 from apt on linux mint I get this error:

E: Version "1.4.10" "teams-for-linux" not found

The command is: sudo apt-get install teams-for-linux=1.4.10

Thanks.

That's because only the latest release is provided on the debian repo: https://repo.teamsforlinux.de/debian/pool/main/t/teams-for-linux/
You can download the .deb file from the GitHub release and then install the local .deb file via sudo apt install ~/Downloads/eams-for-linux_1.4.10_amd64.deb for example.
See #1110

[jijojosephk]

There is nothing in the latest release that could break screen sharing. I'm not sure what's happening

It did work with the 1.4.7 or 1.4.8 version I was using before without a problem. I will try to downgrade and see if I can get it to work.

FYI:

• Clearing the cache and restarting / re-logging in using 1.4.11 did not fix the problem
• Downgraded to the 1.4.10 RPM on my openSUSE and it worked perfectly afterwards

@holle when you say you can't share screen, are you getting the same error mentioned in the issue?

[holle]

@holle when you say you can't share screen, are you getting the same error mentioned in the issue?

@jijojosephk yes, correct. I am (was) seeing the same message telling me teams-for-linux could not access the camera albeit I was already having my camera running and happily chatting with a colleague.

[woernsn]

@jijojosephk, for me it also is the same error as in the original issue description.
I tried the last versions

• 1.4.9: working
• 1.4.10: working
• 1.4.11:
  

[jijojosephk]

This could have been causing this issue: #1102 (comment)

I'm on wayland so can't debug the same problem. Once pre-release ready for 1.4.12, kindly test.

[jijojosephk]

@holle and @woernsn can you try 1.4.12 ?

[z1atk0]

Same here, Slackware64 15.0 on X11, tarball release of 1.4.11. When I try sharing a screen, I get "Your video isn't working. We couldn't access your camera.". The funny thing is, the camera actually works just fine on meetings. Plus I don't quite get why it would need the camera for sharing a screen in the first place?

Anyway, will try 1.4.12 today ... 🤷‍♂️

[dschrempf]

1.4.12 fixed the screen sharing issue for me on NixOS (unstable).

[jijojosephk]

Sorry for the chaos. I believe 1.4.12 fixes the problem hence closing.

[woernsn]

@holle and @woernsn can you try 1.4.12 ?

Also on my site, 1.4.12 fixes the issue.
Thanks.

[holle]

@holle and @woernsn can you try 1.4.12 ?

@jijojosephk will try later today. But I guess from the others feedback it will work 😉
Thanks for the quick reply, the quick fix and the effort 👍

@jijojosephk I had the chance to call a co-worker: yes, screen sharing alongside video and sound etc. works perfectly.
Thanks again 👍

[z1atk0]

Yup, 1.4.12 works fine again here as well. Thanks! 👍 😃

[AntoninSlejska]

I have installed 1.4.12 the deb package. My colleages have then complained, they hear me twice, when I start to share my desktop.
I have installed 1.4.12 the snap package. The screen sharing did not work then anymore.
I have installed 1.4.12 with the following commands:

sudo mkdir -p /etc/apt/keyrings
sudo wget -qO /etc/apt/keyrings/teams-for-linux.asc https://repo.teamsforlinux.de/teams-for-linux.asc
echo "deb [signed-by=/etc/apt/keyrings/teams-for-linux.asc arch=$(dpkg --print-architecture)] https://repo.teamsforlinux.de/debian/ stable main" | sudo tee /etc/apt/sources.list.d/teams-for-linux-packages.list
sudo apt update
sudo apt install teams-for-linux

The screen sharing works perfect now. I will write an update, if there are any other problems.

[jijojosephk]

Thanks @AntoninSlejska ! snap package has been a pain since a few months.
