Hi, Here are the instructions to solve this:
1. Add the notifications key to your schema: sudo gedit /usr/share/glib-2.0/schemas/org.gnome.desktop.screensaver.gschema.xml And add a new key: <key type="b" name="show-notifications"> <default>true</default> <summary>dummy summary</summary> <description></description> </key> 2. Save the file and recompile the schemas: sudo glib-compile-schemas /usr/share/glib-2.0/schemas/ After that, everything should work. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1117637 Title: Brightness and Lock option in System Settings crashes because of glib's schema missing key To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1117637/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
