Yes, that's likely. I'll take patches to activate this plugin in other environments if they're provided. Follow the logic that we've used for gnome-panel.

This package is only a Recommends of ubuntu-desktop. It's an undeclared dependency which isn't actually necessary. [ Proposed fix ] Check for org.gnome.Panel (for gnome-panel environments) and com.canonical.Unity (for Unity environments). Unity also provides org.gnome.Shell so check $DESKTOP_SESSION in that handler to only run in a real gnome-shell session. [ Test case ] Remove the gnome-screensaver package. In a gnome-panel based or a Unity session, launch gnome-settings-daemon. Make sure your media keys work with the update. [ Regression potential ] This changes activation of a plugin. There's a chance it could be wrong. If it doesn't work, make sure the plugin is enabled: $ gsettings get org.gnome.settings-daemon.plugins.media-keys active and then run $ gnome-settings-daemon --debug --replace | tee /tmp/g-s-d.log wait 5 seconds, try pressing some media keys, then attach /tmp/g-s-d.log [ Original report ] With the latest g-s-d any custom key-bindings fail as do some 'default* ones (system Test cases - remove gnome-screensaver open keyboard panel > shortcuts> system change Log out to a new binding log out/in thru indicator-session Try the new binding, nothing happens open keyboard panel > shortcuts> custom create a new binding for some command log out/in use binding, nothing happens ProblemType: Bug DistroRelease: Ubuntu 13.10 Package: gnome-settings-daemon 3.8.5-0ubuntu7 ProcVersionSignature: Ubuntu 3.11.0-11.17-generic 3.11.3 Uname: Linux 3.11.0-11-generic x86_64 ApportVersion: 2.12.5-0ubuntu1 Architecture: amd64 Date: Wed Oct 9 14:03:35 2013 InstallationDate: Installed on 2013-10-03 (6 days ago) InstallationMedia: Ubuntu 13.10 "Saucy Salamander" - Beta amd64 (20131002) MarkForUpload: True SourcePackage: gnome-settings-daemon UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/1237564/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
