After upgrading to 17.10, my System Load Indicator (indicator-multiload) applet turned into a tiny little box where it's no longer possible to see the different live graphs.

As per How To Use Indicator Applets on GNOME Shell, I tried enabling KStatusNotifierItem/AppIndicator Support via the switch on that page, but then the widget turns into ERROR, and nothing else happens.

Is there a Gnome version of this application we should be using instead? If not, would it be possible to get System Load Indicator working again somehow?

This is a bug, and it's been already reported to developers of the app:


You can upvote it if you wish, to let the developers know that it does matter for you -- maybe it'll somehow speed them up in releasing the fix?

  1. Report that it affects you -- this will add 4 points of "bug heat" ("hotness").
  2. Subscribe to bug's notifications -- it'll add 2 points.

(It currently has 48 points.)

But in comments in the very bug I found that there is already a not bad extension for gnome with the same features:


So there's probably no need at all to fix this bug, if one can simply use existing extension?

Its installation is a little bit tricky, but there are instructions there, I simply followed them and right now I've managed to successfully install it.

Try it yourself!

    Installing it via apt didn't work, but flipping the switch on the extention page certainly did. Thanks!

    on 18.04, gnome-shell-extension-system-monitor I found with synaptic, and only had to run this on commandline to enable it: gnome-shell-extension-tool --enable-extension=system-monitor@paradoxxx.zero.gmail.com (I actually installed gir1.2... before doing it tho), it appeared on the systray, I still dont get the webbrowser part but w/e :) Jan 25, 2019 at 21:43

Installing Gnome extensions support and the system-monitor extension - https://extensions.gnome.org/extension/120/system-monitor/ - was the solution for me.

In case you also, like me, were not familiar with the gnome extensions, please follow these steps:

  1. Install add-on for your web browser:

For Google Chrome, Chromium, and Vivaldi, install the add-on via chrome web store. That's what I have done, but there are also add-on for other browsers: For Firefox, install add-on from Mozilla Addons site. For Opera, install it from Opera Addons site.

  1. Open terminal either via Ctrl+Alt+T, or by searching “terminal” from app launcher. When it opens, run the command to make it work in Chrome:

    sudo apt install chrome-gnome-shell

  2. The system-monitor extension has some requirements - run the following command on the terminal:

    sudo apt-get install gir1.2-gtop-2.0 gir1.2-networkmanager-1.0 gir1.2-clutter-1.0

  3. Finally go to extensions.gnome.org via your browser (I have used Chrome), install any Gnome Shell Extension by turning on the switch on the web. For the system-monitor extension, the link is https://extensions.gnome.org/extension/120/system-monitor/.

After upgrading to Ubuntu 17.10 I also had this problem and I was missing the indicator-multiload features. I now like this system-monitor extension even more - it looks better, has relevant information, it is easier to configure and it is easy to find and install, at least when you get into the gnome extensions.

  • but will it be placed on the system tray or I will have to open a web browser? the systray is the right location for such kind of things (fast monitoring). Jan 25, 2019 at 21:18

    It will be placed on the system tray. The Gnome extensions add-on provides only an easy way to install it. Just have a look at the link from the extension. Mar 26, 2019 at 10:55
