A few days ago, I installed the latest Zoom client (Version 5.7.5 (29123.0808)) on Fedora Linux Release 32. Now «Share Screen» offers only the whiteboard under «Basic». There is no option to actually share the video screen. Yes, I rebooted the system to be sure there was not some other problem. The old client worked great, though it may have been a few versions back. Does anyone else have this problem?

That was it! I’m not sure why it worked before, but I switched over from Xwayland (Wayland) to Xorg following the instructions at https://docs.fedoraproject.org/en-US/quick-docs/configuring-xorg-as-default-gnome-session/. Now screens and application windows appear in the Share Screen dialog window. Thanks!

Can you verify if you are utilizing Wayland with your Linux set up? If so, you will need to launch your Linux session with Xorg instead. From the support article: https://support.zoom.us/hc/en-us/articles/201362153-Sharing-your-screen-content-or-second-camera#:~. .

«Linux sessions utilizing Wayland can only share an entire desktop or whiteboard. To share just a specific application, you need to launch your Linux session with Xorg instead.»

Let me know if you continue to experience any other issues or if this resolves what you are experiencing. Thank you.

Meh, this isn’t really a «solution» it’s more accurately a workaround for a Zoom bug

And a poor workaround at that. I believe Wayland is in the process of replacing Xorg entirely, and right now Zoom is the ONLY app I’m forced to use with Xorg.

Agreed. Also, it seems to work for very specific distributions and on GNOME only. KDE users are left out in the cold with Wayland+Zoom. This is a bit surprising since KDE is built on top of Qt, just like Zoom. All Qt apps work perfectly under KDE . except Zoom!

What sorcery has Zoom devs added (or not) to Zoom that makes it so hard and unusable on Linux, in general, and KDE/Wayland, in particular?

Btw, I’ve heard my GNOME friends complaining too!

In short, they simply never added Wayland support

Fortunately it sounds like they are now doing that, though it’s unclear when we might expect to see it

For more context, Zoom incorrectly implemented their screensharing on modern gnu+linux distributions which use Wayland. Zoom did not introduce Wayland support until March 1, 2020 version 3.5.361976.0301. This was broken upon release because they did not use the correct API (gdbus-org.freedesktop.portal.ScreenCast) which has been available since early 2018 : https://github.com/flatpak/xdg-desktop-portal/releases/tag/0.10. This resulted in issues for multi-monitor setups, problems with HiDPI screens, unusable performance, and other glitches from the beginning, and now it is broken completely.

Many users are switching to affordable, reliable, backed-by-open-source options like https://8×8.vc, powered by Jitsi (plus, they didn’t lie to their users about end-to-end encryption and get sued). The screenshot API exists only for the system to take screenshots (of course). It is very inefficient for video but what’s worse is it is also completely insecure because in order for it to be publicly enabled, applications have full access to record your entire screen without explicit permission.

The correct API was designed for video, and gives the user control over sharing specific windows/apps or the entire screen, so no app gets to spy on your screen without your permission. So when Zoom created their implementation they used the wrong API, and for the almost two years since then Zoom still didn’t update, ignored the users with issues, did not monitor for deprecating APIs, and did not test upcoming gnu+linux distributions like Fedora to see that the API they use was incorrect, long been deprecated, and imminently disabled. This left many users and developers to do the testing and investigation for them, but still took nine months to be recognized. Finally, they are working on this now, so we will see how long the fix takes.

How to share a screen in MS Teams or Zoom from Ubuntu 22.04

on Ubuntu 22.04 LTS (42.0, Wayland) no screen shows up after clicking on «share screen».

Hardware: Lenovo ThinkPad X1 Yoga 3rd, Mesa Intel® UHD Graphics 620 (KBL GT2), Intel® Core™ i7-8550U CPU @ 1.80GHz × 8 connected with two monitors via Thinkpad Thunderbolt 3 dock.

Is there a configuration issue, or is screen sharing not supported?

Going back to Xorg which is regularly proposed as a solution to the above problem is pretty much like telling someone to ditch their car and go back to horse and carriage if they have a flat tire. One of the reasons screen-sharing works under X and not under Wayland is that X has no concept of security. Every X application has full access to the frame buffer and thus sees everything. Disabling security — however crude a solution that may be — does the trick for now and you are not worse off than with Xorg and at least you can disable it for the duration of your screen sharing session only.

Finally some common sense. I think the best solution for now is just to use Zoom from the browser (and complain to Zoom that this is ridiculous, Ubuntu 22.04 is recent but Wayland has been around for years now). Note: to make screen sharing work in Chrome it’s sufficient to enable WebRTC PipeWire support in chrome://flags.

It would be good if these were two separate question posts, as the solution for Zoom may not be the same as the solution for Microsoft Teams.
