Zoom screen sharing not working on Ubuntu 24.04

[dmk1]

I have two computers that are both running Ubuntu 24.04 with Zoom 6.4.13 (2309) installed from the .deb. On one computer I am able to share the screen, but on the other, I cannot for some unknown reason. When I select "share" at the bottom of the zoom meeting window, it opens up the "Select a window or application that you want to share dialog", but when I select what I want to share and hit the "share" button at the bottom, nothing happens. The same procedure on the other computer then opens up a second system dialog asking me what screen to share and then it shares the screen, but on this computer, nothing happens.

What is the problem and how might I go about diagnosing it?

Thanks,

David

Zoom screen sharing on Ubuntu 24.04 often fails due to Wayland compatibility, while it generally works smoothly under X11. To confirm, run echo $XDG_SESSION_TYPE. If it returns “wayland”, log out and switch to “Ubuntu on X11” from the gear icon on the login screen—this alone usually fixes the issue. If you'd rather stay on Wayland, ensure the required portals are installed: 

sudo apt install xdg-desktop-portal xdg-desktop-portal-gtk

Then launch Zoom from the terminal with zoom, share your screen, and observe any errors for clues. You can also compare settings and portal installations between the working and non-working machine using:

journalctl | grep xdg-desktop-portal

Finally, try updating or reinstalling Zoom from the official .deb package to ensure you’re on the latest version.

This kind of diagnostic clarity is especially useful in roles where smooth virtual collaboration is essential, such as in guaranteed rent UK services managing remote property operations.

I’m running into the same issue on Ubuntu 24.04—screen sharing just doesn’t respond, even though all the permissions look fine. I tried reinstalling Zoom and making sure Wayland wasn’t the default session, but no luck so far. Hopefully Zoom pushes an update soon with better support for the new Ubuntu version. you can also check this thread https://community.zoom.com/t5/Zoom-Meetings/Screen-Share-is-broken-on-wayland/m-p/204495
