I use an external monitor and I've just upgraded to Bionic Beaver 18.04 from Xenial Xerus 16.04. The differences are striking ok, but the most annoying are:
- when I ALT+TAB the app switcher is shown on the laptop monitor instead of the one where is the active window.
- the top bar (with clock and tray icons) is shown only on the laptop monitor.
Does anybody have a workaround?
