Unable to screen share in ubuntu 22.04

Still does not work with version 5.11.3 (3882) on Ubuntu 22.04 with multiple screens on Wayland. Shared  screen is always black. It works if I use only the notebook screen and no additional screens. I also tried to share only windows - no success. But might be related to the Gnome version - 42.2.

I just updated my ubuntu instance to 22.04.

I have the latest zoom version as of writing this: 

Version: 5.11.10 (4400

I am running on a doula monitor setup.

I can not share my screen at all. Only whiteboard and system capture.

Is there a way to keep wayland and share screen?

I read the release notes and saw quite a couple of bugfixes regarding wayland.

Can I assist with any logs?

Problem is present again in Zoom 5.11.10 (4400) on Ubuntu 22.04.   The only options are "Use System capture" and "Whiteboard".  "Use System capture" doesn't do anything. 

UPDATE 9/18/22

I was able to fix screen sharing in XFCE Desktop Environment. I installed a package for the Weston Compositor, this apparently installs all the wayland files. I used the command >sudo apt install weston  It then recomended another package which I also installed. I then ran weston from the command line and it popped open a window with a terminal. Wasn't much to be done there other then to confirm that the package was installed and it could create a window and terminal in the XFCE environment. Restarted the computer, logged in and fired up zoom and works like a champ! 

I can share individual apps or the entire desktop, and as an added bonus, when sharing the entire desktop, I can scroll through all 4 of my virtual desktops, so the screen sharing has full cooperation with XFCE. Beautiful!

Original Post:

I figured I would reply here since I am having a very similar problem in that screen sharing is not working when I join a meeting. This is critical since I am taking a programming class online and it is imperative that screen sharing work.

Quick History:

Zoom screen sharing worked just fine about a year ago, at some point I updated Debian and Zoom and screen sharing was broken. I was able to find this thread and was able to make sure I was using X windows and I was again able to share the desktop only, where as before I could share individual screens. Summer break goes by I have again updated Debian and the Linux kernel a few more times, and of course I have updated Zoom to the latest version, and once again screen sharing is broken.

My exact problem is this: When in a hosted meeting, if I click on the 'share' (or try alt 's') button, the button flashes in recognition that it is being clicked on, but nothing happens, no error, no dialog box, nothing. I have checked all my zoom settings and have made sure screen sharing is enabled, I have checked and unchecked all possible combination of settings and nothing makes a difference. Other students (Windows) are able to share screens without issue so it is not a host setting issue.

In addition, I have tried joining using both Chrome and Firefox by clicking on a session link with no solution, I have tried opening, logging in the desktop app and joining the meeting and that has also not worked. I have also tried hosting a zoom session from my Google Pixel 4a cell phone, then joining from my desktop and again I am unable to share the screen from the desktop. 

All other Zoom functions are working correctly including sharing a whiteboard, so it is obviously capable of opening separate windows. All functions are operating correctly, video, audio, etc etc.

System Details:

Debian Version 11 (bullseye), Linux Kernel 5.10.0.18, Desktop Environment Xfce 4.16, Zoom Version: 5.11.10 (4400)

I have modified the /etc/gdm3 config file to Wayland = False (Note* This actually fixed screen sharing the first time)

Verified I am running X11 by running the command:

sudo echo $XDG_SESSION_TYPE
x11

I also have all the Gnome desktop binaries installed although I do not use Gnome as my Desktop Environment. I can offer up logs, screen shots, etc if it will help resolve the problem. Thank You for your prompt attention to this situation. I will update this if I am able to find a solution in the interim.

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_ "

I've just installed "Version: 5.12.2 (4816)" on "Ubuntu 22.04.1 LTS". Still doesn't show me anything but whiteboard to share.

I've just installed the latest zoom "Version: 5.12.2 (4816)" on "Ubuntu 22.04.1 LTS".
It still shows only whiteboard to share.

I saw this workaround in this thread.
However, switching to Xorg just to share things in Zoom is not a viable option really.

Firstly you need to install the Xorg package

sudo apt-get update
sudo apt-get install xserver-xorg

In this file /etc/gdm3/custom.conf (to access it for editing, you could run sudo nano /etc/gdm3/custom.conf), uncomment (remove the leading #) this line

#WaylandEnable=false

To

WaylandEnable=false

save and exit.

Then run this command in the terminal to restart gdm3

sudo systemctl restart gdm3.service

 It will log out and log in automatically. Just wait...

Hi, everybody

I had the same problem. My OS is Ubuntu 22.04 and Zoom is 5.12.9.  I was running on Wayland but with xorg driver (I can't remember why).

So I went on "software & updates" - "additional drivers" and selected the latest NVIDIA proprietary driver (or the open source if you prefer, actually ver 520).

After a restart everything is working fine.

Hope it could help
