Since the update to 20.04 from 16.04, I see top bar with date and time and volume control --- but only on the primary screen of my computer. On the other screens, the top bar is not shown.
I've searched with duckgo and google but didn't find a solution.
This was asked before, but without an answer.
To be clear, I'm looking for something in a package manager or official channel, and not a custom script I can sideload.
For a solution based on an official package: make sure that you have "Universe" enabled in your repositories:
sudo add-apt-repository universe
and that you're using the GNOME desktop or a derivative.
Search Synaptic (or via apt) for the package:
gnome-shell-extension-multi-monitors
Install it, along with the GNOME tweak tool (package "gnome-tweaks", not "gnome-tweak-tool" - the latter is to access some additional settings):
sudo apt-get install gnome-shell-extension-multi-monitors gnome-tweaks
You’ll have to log out and back in (sometimes just reboot your system). After that, search for the Tweak Tool in GNOME menu and launch it. Select "Extensions" on the left-hand side, and scroll till you see multi-monitors-add-on. Activate the slider.
You should see a dual monitor symbol on your taskbar. Click it and select "Preferences". This prefs page will let you tweak all sorts of options... including "Show panel on additional monitors", which is the setting that you are looking for.
Multi Monitors Add-On can do the trick.
As per Installation from git:
git clone git://github.com/spin83/multi-monitors-add-on.git
cd multi-monitors-add-on
cp -r multi-monitors-add-on@spin83 ~/.local/share/gnome-shell/extensions/
Restart the shell and then enable the extension.
