@Romano Giannetti: If in tweak tools you deselect "file manager handle desktop", you then have the background black until you select a different background. After changing background everything should be OK if Nautilus doesn't handle the desktop. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1132033 Title: Gnome-Shell activities shows black background To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-shell/+bug/1132033/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
