[SOLVED] Teamviewer dumps core on XFCE Wayland
Hello,
I have a running XFCE Wayland system here and tried to install and run Teamviewer, but the the start fails with a core dump. It works on KDE Plasma with Wayland. What must be changed to run Teamviewer in XFCE Wayland?
teamviewer info
TeamViewer 15.79.4 (DEB)
grep: /opt/teamviewer/config/global.conf: Keine Berechtigung
TeamViewer ID:
Try restarting the TeamViewer daemon (e.g. teamviewer --daemon restart)

How are you starting xfce ?

Re: [SOLVED] Teamviewer dumps core on XFCE Wayland
The output was taken from journalctl, "coredumpctl info" is similar.
XFCE start: sddm-helper[593]: Starting Wayland user session: "/usr/share/sddm/scripts/wayland-session" "startxfce4 --wayland"
The drop-in mentioned here
https://aur.archlinux.org/packages/team … ent-868456
doesn't help.

Re: [SOLVED] Teamviewer dumps core on XFCE Wayland
That drop-in is for teamviewer on X11, so not surprising it fails on wayland. It does suggest XDG_SESSION_TYPE plays a part though.
Please post the output of printenv XDG_SESSION_TYPE .
journalctl , coredumpctl and many other commands by default output to a pager that truncates long lines. Redirecting the output to a file helps to get the full output.
Execute
$ coredumpctl info teamviewer-pid > coredump-xfce-teamviewer.txtand post the contents of the file.

Re: [SOLVED] Teamviewer dumps core on XFCE Wayland
Ok, the service is supposed to run as root, should have no trouble accessing /var/run/teamviewerd.pid but still objects to it.
=> We''ll need the untruncated error message to see what conditions it expects for the file.

Re: [SOLVED] Teamviewer dumps core on XFCE Wayland
So basically the PID seems a red herring, from the coredup TV aborts out of
#2 0x00007f8b7350e15e _ZN22QGuiApplicationPrivate25createPlatformIntegrationEv (libQt5Gui.so.5 + 0x10e15e)What is this even? There's a system service trying to run a GUI client?
You'll have to jump through some hoops just to get a gui client to run as root (what's a horrible idea anyway)??
Anyway, since it aborts creating a platform plugin, do you have https://archlinux.org/packages/extra/x8 … 5-wayland/ ?

Re: [SOLVED] Teamviewer dumps core on XFCE Wayland
no, the system service only starts the teamviewer daemon, and this works despite of the warning about the pid file. I have the same warning on KDE Plasma where teamviewer works. Teamviewer itself is started as user and there the dump occurs.
Yes, qt5-wayland is installed.
I suppose either a missing library (available on KDE Plasma wayland, but not on XFCE wayland) or some incompatibility either in the packages or in the config, e. g. for starting XFCE with wayland labwc is required.

Re: [SOLVED] Teamviewer dumps core on XFCE Wayland
When you're starting the teamviewer GUI from an interactive shell, does it print the abort message there?
Does "QT_QPA_PLATFORM=xcb teamviewer" work? (the executable command is a guess)

Re: [SOLVED] Teamviewer dumps core on XFCE Wayland
Start from interactive shell:
teamviewer
Init...
CheckCPU: SSE2 support: yes
Checking setup...
Launching TeamViewer ...
Launching TeamViewer GUI ...
Abgebrochen (Speicherabzug geschrieben) teamviewer
QT_QPA_PLATFORM=xcb teamviewer - works!!! Thanks!
echo $QT_QPA_PLATFORM
wayland
Can you give me some info how do you find this solution?

Re: [SOLVED] Teamviewer dumps core on XFCE Wayland
It's a common workaround for apps which misbehave with native Wayland, forcing Xwayland rather.
Given the newborn-baby status of XFCE's Wayland implementation, more likely the compositor than the app in this case if it works fine natively with other Wayland compositors (KDE, etc.).

Re: [SOLVED] Teamviewer dumps core on XFCE Wayland
Which would be worth a test, but it seems implausible that Qt tries to load the wrong QPA (as that would be xcb, wayland would be correct and unless you installed the arcan QPA from the AUR those are the two options)
What's most likely is that teamviewer comes w/ bundled QPAs and cannot use the system ones and simply doesn't ship a wayland QPA - in that case it would also fail on eg. weston.

OP confirmed multiple times upthread it works on KDE. Perhaps silently falling back to Xwayland in that case.
Even Arch-packaged Weston will utilize Xwayland if xorg-xwayland is installed.
To pin the issue on Teamviewer rather than XFCE, remove the xorg-xwayland package (and buddies) from the equation and ensure a purely native Wayland compositor implementation (Sway or Weston), where it's optional.

Re: [SOLVED] Teamviewer dumps core on XFCE Wayland
Or https://wiki.archlinux.org/title/Waylan … plications on KDE… it would be nice to have the abort message.
@Dieter can you confirm that XFCE is actually running on wayland and you're not enforcing the wayland QPA on X11?
Do other Qt client work w/ "QT_QPA_PLATFORM=wayland some_qt_app"?

Out of curiosity I built teamviewer with debug symbols and gathered a stacktrace.

Hyprland git built with cmake -DNO_XWAYLAND:STRING=true here.
EDIT: perhaps there's a way to force teamviewer to use system libs instead of bundled.

Re: [SOLVED] Teamviewer dumps core on XFCE Wayland
In the most simple scenario (LD_LIBRARY_PATH) just move away the bundled libs, but the bundled ones are often customized and ABI incompatible 
You could also try to LD_PRELOAD the system libs (same caveat, thoug)

Re: [SOLVED] Teamviewer dumps core on XFCE Wayland
Well it's right in the pkgbuild..
# Uncomment to use system's native libraries. This can save around 150MiB of disk space
rm -rf "${pkgdir}"/opt/teamviewer/tv_bin/RTlibAnd of course makes no difference as we're more than a year after QT5's EOL these days and ABI wouldn't have changed in a much longer while.
My only interest in this topic was insofar as it relates to the app vs compositor support aspect. QT5 and X11 requirements are quaint tho.
