Screen Share Not working in Ubuntu 22.04 (In all platforms zoom, teams, google meet, anydesk , etc.,)

Question

Ubuntu 22.04 has a bug which is we can't share our screen on any platforms.

Answer 1

The issue with Ubuntu 22.04 is that it now uses a display feature called wayland by default, while in versions prior to 21.04 Ubuntu defaulted to using xorg as its display server. Wayland does not support screen sharing by default (until now, at least!).

To check which display system your Ubuntu is using, please enter this command

echo $XDG_SESSION_TYPE

If the above command outputs wayland, your system is using wayland.

In order to use screen sharing, we have to disable wayland and enable xorg (x11). To do this,

Please go to this file

sudo nano /etc/gdm3/custom.conf

Uncomment this line.

WaylandEnable=false

Reboot your system.

Voila! You can share your screen. You can confirm this by re-entering this command.

echo $XDG_SESSION_TYPE

Now it should display x11.

Answer 2

Only works for web browser

Go to chrome://flags/#enable-webrtc-pipewire-capturer using the address bar of your browser.

Click the drop down menu, and click Enabled.

Finally Restart the browser

This will enable the browser to prompt screenshare access

Answer 3

For Slack in-app screen recording and screen sharing:

1. Quit the Slack app completely (use Quit from the tray icon).
2. In the terminal:

slack --enable-features=WebRTCPipeWireCapturer

3. See if it works.
4. (Optional) Persist the change across reboots:

gedit admin:///usr/share/applications/slack.desktop

In text editor find a line that says:

Exec=/usr/bin/slack %U

Change the line to say:

Exec=/usr/bin/slack --enable-features=WebRTCPipeWireCapturer %U

That's it. Tested on Ubuntu 22.04LTS and:

$ slack --version
4.27.156

$ echo $XDG_SESSION_TYPE
wayland

$ dpkg -l | grep -i pipewire

Answer 4

Since Wayland is not supporting screen share by default, there is already an experimental way with chrome browser.

First you need to export the metadata API from the pipewire media sessions.

sudo mkdir -p /etc/pipewire/media-session.d/
sudo cp /usr/share/pipewire/media-session.d/media-session.conf /etc/pipewire/media-session.d/
sudo sed -i 's/#metadata/metadata/g' /etc/pipewire/media-session.d/media-session.conf

At chrome experimental features enable the WebRTC PipeWire support

chrome://flags/#enable-webrtc-pipewire-capturer

Restart the browser and now you can share your screen.

Answer 5

I tried the global.context.unsafe_mode=true solution, but Google Meet was still showing black screens, so didn't test it any further.

What worked for me was switching to X11/Xorg, which I did by

• logging off
• clicking gear icon at bottom right
• selecting "Ubuntu on Xorg"
• logging back in

Answer 6

As mentioned this is a Security Feature of Wayland. You can either use XOrg or disable the save mode of Wayland by doing:

1. Press Alt + F2
2. Type lg and press enter
3. Disable save mode by typing global.context.unsafe_mode=true and enter

This will work till you reboot/log out. I wrote a small Gnome Extension which does can disable the safe mode on demand. See https://github.com/julianpollmann/zoom-wayland-gnome-extension

Answer 7

I changed graphic drivers (in additional drivers menu) from xorg-server to Nvidia proprietary. It worked for me.

Answer 8

Now the screen sharing in Wayland is available with the zoom client for Ubuntu.

Check the release notes in 5.11.0 (3540) release.

Answer 9

I was resolved by going to chrome://flags/#enable-webrtc-pipewire-capturer and changing the value from Default to Enabled.

then

Search for the file.conf in /etc/gdm3/ in my case, Ubuntu 20, it's custom.conf

sudo nano /etc/gdm3/custom.conf

uncomment the line

#WaylandEnable=false to be WaylandEnable=false

then reboot

"uncommenting that line will use the Xorg display manager instead of Wayland "
