I have a very strange problem. I have installed Ubuntu again and I have of course installed gnome-shell and gnome-tweak-tool. The tweak-tool doesn't start when I click on the icon. It loads a few seconds, but then it's disappeared. Can anyone tell me what I'm doing wrong?
If I run gnome-tweak-tool in the terminal I get this error:
WARNING : Schema /usr/share/glib-2.0/schemas/org.gnome.shell.gschema.xml missing summary text: <key name="saved-im-presence" type="i">
