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!

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

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.

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

Just install

sudo apt-get install xorg openbox
