Gnome shell system monitor extension

Build Status






This extension requires GNOME Shell v3.26 or later. Please see the alternate branches gnome-3.0 and gnome-3.2 if you are using an older version of GNOME Shell (check with gnome-shell --version).

Before installing this extension, ensure you have the necessary system packages installed:

  • On Ubuntu:

    $ sudo apt install gir1.2-gtop-2.0 gir1.2-nm-1.0 gir1.2-clutter-1.0
  • On Debian:

    $ sudo apt install gir1.2-gtop-2.0 gir1.2-nm-1.0 gir1.2-clutter-1.0
  • On Fedora:

    $ sudo yum install --assumeyes libgtop2-devel NetworkManager-glib-devel
  • On openSUSE (Leap 42.1):

    $ sudo zypper install gnome-shell-devel libgtop-devel libgtop-2_0-10

Additionally, if you have an Nvidia graphics card, and want to monitor its memory usage, you'll need to install nvidia-smi.

For the browser installation (recommended), you will need the GNOME Shell integration browser extension for Chrome, Firefox or Opera.

Note: If you're using Firefox 52 or later, you will also need to install chrome-gnome-shell. The instructions are available on the GNOME wiki.

Browser installation

It's recommended you install the extension via the Gnome Shell Extensions website.

Visit this extension's page on, preferably in Firefox, and install by clicking the toggle button next to the extension's name.

If the install was successful, the toggle button should now show "ON". If it failed, ensure that you installed all the necessary dependencies, and that you granted the browser permission to install extensions when prompted. Additionally, rebooting gnome-shell may help (type Alt + F2 and input r in the prompt).

Repository installation

  • Extension is in Fedora 25, 26, 27 and Rawhide repositories, you can install it for all users with the following command:

    $ sudo dnf install gnome-shell-extension-system-monitor-applet

  • Enable it with gnome-tweak-tool or gnome-shell-extension-tool

Manual installation

Download the ZIP/Tarball, extract the archive, open a shell into its directory, and run:

make install

Alternately, if you plan on doing development on the extension, or testing modifications, it's advised you checkout the Git repository and install a symlink. First, install git if you don't have it: (sudo apt-get install git-core, sudo pacman -S git, etc), then run:

git clone git:// $PROJECT_NAME
mkdir -p ~/.local/share/gnome-shell/extensions
cd ~/.local/share/gnome-shell/extensions
{ [ -d "./$PROJECT_NAME" ] || [ -L "./$PROJECT_NAME" ]; } && rm -Rf "./$PROJECT_NAME"
ln -s $GIT_PROJECTS/gnome-shell-system-monitor-applet/$PROJECT_NAME
gnome-shell-extension-tool --enable-extension=$PROJECT_NAME

And restart gnome-shell (Alt + F2, then r) or reboot the machine.

On openSUSE you need to install a devel package that provides the gnome-shell-extension-tool command:

$ sudo zypper install gnome-shell-devel

  1. To create a zip file with the specified version number, ready to upload to Gnome Shell Extensions or similar repository, run:

    make zip-file VERSION=

To determine the version number to use, check the extensions site and increment from the largest published version.

The specified version number is just for documentation and isn't strictly necessary in the uploaded file, since the extensions website will dynamically set this and override whatever we enter.

  1. Once uploaded, create a Github release with the same version number.
