Qubes OS release

R4.2

Brief summary

If I try to screenshare with fc37 dom0 as the sender, I get error messages and it won't work.

Steps to reproduce

  1. Install qubes-video-companion in dom0 and a template qube.
  2. From an app qube, try to qubes-video-companion screenshare and select dom0 as the sender.

Expected behavior

It works.

Actual behavior

In dom0 journal:

dom0 qvc.ScreenShare+-disp6823[12773]: Traceback (most recent call last):

dom0 qvc.ScreenShare+-disp6823[12773]: gi.repository.GLib.GError: g-io-error-quark:  Error calling StartServiceByName for org.freedesktop.Notifications: Timeout was reached (24)

Commenting out Notify.Notification.new(app, msg, icon).show() fixed this for me. But this probably shouldn't be a solution so this still needs diagnosis.

I have encountered this also. I believe the Dom0 package libappindicator-gtk3 is the problem. The package libayatana-appindicator-gtk3 is not available on Fedora 37 but is on Fedora 38 and beyond. But I cannot be certain until there is a new release on Dom0 based on newer Fedora. I am using KDE and notify-send works normally.

The important part of the log below is:

org.kde.knotifications: WaitForName: Service was not registered within timeout
