Question: I've found this post when searching for something to display CPU, memory utilization in Ubuntu 20.04 top pane.

[How do I show memory usage information in top bar or as notification?](https://askubuntu.com/questions/1057164/how-do-i-show-memory-usage-information-in-top-bar-or-as-notification)

According to the accepted answer ...

```
sudo apt-get install gnome-shell-extension-system-monitor

```

I did try the solution given, rebooting the computer, but nothing happens.

I can't comment there as `50 reputations` are required which I don't have yet at the moment.

How do I get this utility appear on the top pane?

Also, if there is an alternative/probably better tool, let me know.

Answer: 
What worked for me just now was:

```
gnome-extensions enable system-monitor@paradoxxx.zero.gmail.com

```

I didn't like the idea of installing `gnome-tweaks`. Resource monitor is core functionality to me.

No reboot needed (though I had already, to no obvious effect, so might not hurt). The notifications popped up there immediately.
Original extension
------------------

To get [Paradoxxxzero GNOME Shell system monitor extension](https://github.com/paradoxxxzero/gnome-shell-system-monitor-applet) working on Ubuntu 22 LTS, you need to:

1. Check [here](https://github.com/paradoxxxzero/gnome-shell-system-monitor-applet/releases) if updated version was published recently.
	* Install directly from Ubuntu Extension Manager if it was by searching `system-monitor@paradoxxx.zero.gmail.com`
	* Follow the guide otherwise
2. Install its dependencies `sudo apt install gir1.2-gtop-2.0 gir1.2-nm-1.0 gir1.2-clutter-1.0 gnome-system-monitor`
3. Download and install [latest version](https://github.com/paradoxxxzero/gnome-shell-system-monitor-applet/tree/master/system-monitor%40paradoxxx.zero.gmail.com) of extension manually ([Method#3](https://itsfoss.com/gnome-shell-extensions/)). DO NOT install with other utilities (e.g. browser, Extension Manager) as these have older published versions at the time of this post.
4. Restart OS (there is no reload mode in Wayland as I can see)
5. Enable extension with Ubuntu Extension Manager
6. You may need to tweak the code if you get an error. See [here](https://github.com/paradoxxxzero/gnome-shell-system-monitor-applet/issues/749) and [here](https://github.com/paradoxxxzero/gnome-shell-system-monitor-applet/issues/737).

Alternative extension (fork)
----------------------------

There is a fork of the same extension at <https://extensions.gnome.org/extension/3010/system-monitor-next/> which have fixes in place while original extension is being updated.
However, you should make your own decision if you trust the fork in the long term.
