For Ubuntu, Fedora Workstation, and other Linux with recent GNOME Desktop, there’s now a new extension to enable the top-bar in multiple monitors.
As you know, GNOME top-bar by default only shows in the primary display for multi-monitors working in the “Join Mode”.
There was a multi-monitors-add-on extension which can add multiple monitors overview and panel. It’s however discontinued and support ends at Gnome 3.38.
