Arch Linux User Repository

@Rhinoceros - I finally got screen sharing to work under KDE with Wayland. Looks like I'm using the same versions as you:

• Zoom 6.2.10
• pipewire 1.2.6

I followed the Screen share section on the Zoom wiki page:

https://wiki.archlinux.org/title/Zoom_Meetings

The only thing I didn't need to do was set XDG_CURRENT_DESKTOP=gnome. I followed the other steps, and now I can choose my desktop/window to share. Prior to following the wiki I couldn't stop screen sharing without the hanging issue, which I was experiencing prior to 6.2.10.

The workaround offered in the previous comment

GDK_BACKEND=wayland zoom

Does not work on DE LXQt 2 and WM OpenBox.

zoom 6.2.6 will start in an XFCE X11 session when GDK_BACKEND is set to wayland. Screen sharing also seems to work, which might mean that the zoom initialization logic which deals with the current environment may have an issue.

E.g. GDK_BACKEND=wayland zoom

If GDK_BACKEND is set to x11, the GUI will not start. Tested on Manjaro.

Upgraded to zoom 6.2.6-1. I still don't get a GUI when I run zoom from the command line.

(People have reported similar issues, but this is a follow up from my original comment here https://aur.archlinux.org/packages/zoom#comment-995848)

@coreyberla I confirm that 6.2.6 does not resolve freezes when stopping screen sharing (gnome wayland)

6.2.6 out, support told me that fixes the freezing issue (after stopping screen sharing), and it.... doesn't.

Just as others have reported, 6.2.5 did NOT fix the crash on ending screen sharing. I am on pipewire 1.2.6.

Ugh, zoom-6.2.5 is completely broken, no GUI even when started from terminal. Each release of 6.2 series just gets worse and worse...

I installed zoom (yay -S zoom). The installation works correctly (AFAICT). I am using LXQt as Desktop Environment from a relatively fresh install.

When I run zoom from the command line (simply type zoom, no GUI comes up).

Any help would be greatly appreciated.

I can confirm, 6.2.5 does not solve the freezing when ending a screen share on Manjaro/Gnome with pipewire 1:1.2.5-0.
