    The issue with Ubuntu 22.04 is using a display feature called wayland. Wayland is not supporting to screen share by default(Untill now, atleast!). In previous ubuntu version we had xorg for display feature.

    To check which display feature your ubuntu is using, please enter this command

    echo $XDG_SESSION_TYPE

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

    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.

    Enjoy!

  2. Only works for web browser

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

    enter image description here

    Click the drop down menu, and click Enabled.

    enter image description here

    Finally Restart the browser

    This will enable the browser to prompt screenshare access

  3. 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.

  4. 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

  5. For Slack in-app screen recording and screen sharing:

    1. Quit Slack app.
    2. In the terminal:
    slack --enable-features=WebRTCPipeWireCapturer
    1. Make it persist across reboots:

    If that works, you can add the flag to the slack.desktop file Exec line. Should look something like: Exec=/usr/bin/slack --enable-features=WebRTCPipeWireCapturer %U

    1. Tested on Ubuntu 22.04LTS and:
    $ slack --version

  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

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

    Check the release notes in 5.11.0 (3540) release.
