Thank you very much Lem, it works with Unity Tweak Tool. In the meantime I discovered that it works also running the following command:
$ dconf write /org/gnome/desktop/wm/preferences/action-middle-click- titlebar "'lower'" It might sound crazy, but this is one of the most important feature to me! Anyway, it would be nice to have the mid-click on the title bar working again by default :) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1283849 Title: New window decorations break middle click title bar To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/1283849/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
