My gut feeling is that the following is the cause: févr. 17 11:09:07 dresden gnome-shell[4485]: Failed to interact with fprintd service: Error: GSettings key enable-authd-authentication not found in schema com.ubuntu.login-screen Stack trace: _checkKey@resource:///org/gnome/gjs/modules/core/overrides/Gio.js:779:23 createCheckedMethod/<@resource:///org/gnome/gjs/modules/core/overrides/Gio.js:729:30 _getDetectedDefaultService@resource:///org/gnome/shell/gdm/util.js:905:34 _initFingerprintManager@resource:///org/gnome/shell/gdm/util.js:526:23 _updateEnabledServices@resource:///org/gnome/shell/gdm/util.js:858:18 ShellUserVerifier@resource:///org/gnome/shell/gdm/util.js:183:14 _createUserVerifier@resource:///org/gnome/shell/gdm/authPrompt.js:147:16 _init@resource:///org/gnome/shell/gdm/authPrompt.js:89:35 AuthPrompt@resource:///org/gnome/shell/gdm/authPrompt.js:66:4 _init@resource:///org/gnome/shell/gdm/loginDialog.js:535:28 LoginDialog@resource:///org/gnome/shell/gdm/loginDialog.js:487:4 _ensureUnlockDialog@resource:///org/gnome/shell/ui/screenShield.js:470:28 showDialog@resource:///org/gnome/shell/ui/screenShield.js:402:14 _initializeUI/<@resource:///org/gnome/shell/ui/main.js:316:26 _prepareStartupAnimation@resource:///org/gnome/shell/ui/layout.js:762:18 _loadBackground/signalId</id<@resource:///org/gnome/shell/ui/layout.js:691:26 @resource:///org/gnome/shell/ui/init.js:21:20
I can't find trace of this error in earlier logs of the system, and it *does* talk of auth prompts... However, I was unable to find any mention of "enable-authd-authentication" in the sources of either gdm3, gcr or fprintd. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2098654 Title: /usr/libexec/gcr- prompter:11:gtk_im_multicontext_set_slave:im_module_setting_changed:g_closure_invoke:signal_emit_unlocked_R:signal_emit_valist_unlocked To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gcr/+bug/2098654/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
