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.

Even current 5.14.0-1 won't start. When trying to start from CLI, no output - just won't start. Once the system tray icon shortly appears but less than second disappears and that's all. When removed ~/.zoom/ folder temporarily to another location and tried to start Zoom again from CLI with clean settings, then I got lots of output and most relevant part:

Client: Breakpad is using Single Client Mode! client fd = -1
libva error: vaGetDriverNameByIndex() failed with unknown libva error, driver_name = (null)
.....

For anyone (@cysp74) getting the following error:

/opt/zoom/zoom : symbol lookup error: /opt/zoom/QtQuick/Controls.2/libqtquickcontrols2plugin.so: undefined symbol: _ZN13QQmlDirParserC1Ev, version Qt_5_PRIVATE_API

Within the PKGBUILD directory try deleting the pkg and src directories, the broken .tar.xz and broken .pkg.tar.zst files, then rebuild the package. That fixed it for me. Or just re-clone the repo and re-build. I suspect there were leftover files from a previous zoom build causing the error.

For the past 7~8 days (with 2 intervening updates of my Linux kernel) I have not been able to connect to any Zoom session with v5.13.11 (1288). The start of this issue coincided with me trying to connect with SSO, through my organization. That one attempt failed for obscure reasons. Since then, nothing 'doing. Error messages are:

either 1) "It looks like we are unable to connect. Please check your network connection again.", obtained when trying to connect to my

or 2) "An unknown error occurred. Please use this meeting through your browser. Error code 5003." ... when trying to connect to my private meeting room

or 3) "Timeout" when trying to login with my account user and password from this desktop app.

No joy either when signing out from all devices from my Zoom profile page and signing back in from this desktop app.

I am stuck. Any pointer welcome.

@zeph2 I had the same error as @aljinovic (i.e. qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found; complete log here ). I didn't have any symbol lookup errors that you and others have reported, so it seems like there might be two different issues.

@aljinovic @terru I have qt5-base installed for other reasons, but zoom still crashes at startup with the same error as reported by cysp74 on 2023-02-09 10:09 (UTC). I have tried playing a bit with qt packages, but I have yet to find a solution on my system. I am using the latest zoom version from AUR.

After using Zoom for two years without any issues, I noticed some weeks ago that I could no longer share my screen (on X11, no Wayland involved): The button to start sharing is there, but the dialog to select a window or full screen etc. didn't appear at all.

Since my searches did not yield any hints, I just wanted to give Flatpak a chance. So I installed it parallel to this AUR. Starting it, I noticed that German translation is missing (not a deal breaker) but it wouldn't "migrate its database" (permissions issues?). So I just uninstalled it a couple of minutes later.

Weird thing is: After that, clicking the "Share Screen" button yielded a dialog again, so that part is back to normal (although I don't see how above actions could have influenced that).

I now face a different issue: I start Zoom, log in, click "Keep me logged in", enter my 2FA TOTP code, and everything is working. But when I quit Zoom (via its notification button, without signing out) and re-start it, I need to log in again. So my login isn't remembered now. That part WAS working correctly before my above actions.

I see this in ~/.zoom/zoom_stdout_stderr.log:

Any idea what could cause and how to tackle this?

@edh this is the error that I found in error log:

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found

I can confirm that after installing qt5-base the issues I was having with newer versions have gone away, though it's worth noting that I hadn't tried the latest version too recently. It's possible my problems were fixed by some other update I installed in the meantime rather than qt5-base specifically.

@aljinovic According to zoom upstream, qt5-base is not a dependency. They ship a bunch of qt packages with the package so having to install qt5-base seems strange.

Zoom was crashing on startup after I tried any of the >5.13.4 versions. Installing qt5-base solved the issue. Is it a new dependency?
