Public bug reported: The video recording toggle is missing from the GNOME Shell Screenshot UI (triggered by Print Screen key). Investigation shows the org.gnome.Shell.Screencast D-Bus service crashes on startup.
**Error when running the service manually:** ``` $ /usr/bin/gjs -m /usr/share/gnome-shell/org.gnome.Shell.Screencast (org.gnome.Shell.Screencast): Gjs-CRITICAL: JS ERROR: Error: Expected type utf8 for Argument 'argv' but got type 'null' canScreencast@resource:///org/gnome/Shell/Screencast/js/screencastService.js:516:18 main@resource:///org/gnome/Shell/Screencast/js/main.js:6:28 @file:///usr/share/gnome-shell/org.gnome.Shell.Screencast:9:7 ``` **Steps to reproduce:** 1. Press Print Screen to open the Screenshot UI 2. Look for the video/screencast toggle (to switch from camera icon to video camera icon) 3. The toggle is missing - only screenshot (image) mode is available **Expected result:** A toggle button should allow switching between screenshot and screencast modes. **Actual result:** Only screenshot mode is available because the screencast service crashes on startup. **System information:** - Ubuntu 25.10 (Resolute) - gnome-shell 49.2-1ubuntu1 - Session type: Wayland **Additional notes:** - The underlying org.gnome.Mutter.ScreenCast API works correctly (verified via D-Bus introspection) - All required GStreamer plugins are installed (gstreamer1.0-pipewire, plugins-good/bad/ugly) - PipeWire is running correctly - This appears related to upstream GNOME Shell MR !2592 (timing issue where GStreamer checks block long enough to trigger service auto-shutdown before initialization completes) **Upstream reference:** https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2592 ** Affects: gnome-shell (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2138437 Title: [gnome-shell 49.2] Video recording toggle missing - Screencast service crashes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/2138437/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
