I have 4GB RAM. When I open Firefox, IntelliJ IDEA or VS Code and some other application my memory is about used up thus my machine hangs and I can't do anything. I can't even close any applications.

Date and time are shown in the top bar so that I can view it any time without any thing typing.

If I would view memory status in this way without typing anything then I can make a decision whether to open an application or whether this application may put my machine in hanging state or not.

Is it possible in Ubuntu 18.04 LTS?

  • VS Code is a unique twist. Are we talking thousands or millions of lines of code? – WinEunuuchs2Unix Aug 8 '18 at 3:35

As pointed out in the other post you want to install the Gnome Shell Extension system-monitor There's a browser plugin and integrations that can allow you to install it from the browser or from the software center as mentioned by @pomsky.

However I've found that the easiest way to install it is to just install it from apt using the debian package

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

This will also pull in all the required dependencies, and after a reboot or log out the system monitor was in the top task bar.

(Note that I think I enabled the swap manually before taking the screenshot.)


You may try a GNOME shell extension called "system-monitor". It does

Display system informations in gnome shell status bar, such as memory usage, cpu usage, network rates…

enter image description here

"system-monitor" depends on a few packages. To install them, run

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

Then log out and log in again.

    I run this command and log out and log in but nothing is shown. – alhelal Jul 18 '18 at 9:07
  • @alhelal That command itself won't do anything, it'll just install dependencies for the "sysrtem-monitor" extension. You'll have to install the extension too. See the top half of the answer. – pomsky Jul 18 '18 at 9:17

    I am in doubt whether it is a web extension or desktop app. Your addressed answer give only browser solution. If it is web app why I need browser setting to install. – alhelal Jul 18 '18 at 9:23

    @alhelal Then open "(GNOME) Software" (the software store application) and search for "system-monitor". – pomsky Jul 18 '18 at 9:33

    @RingØ No, you're confusing two different things. gnome-system-monitor rather confusingly is the GUI application called "System Monitor" which is usually pre-installed and can be found in "Show Applications". This one is a GNOME shell extension called "system-monitor", see its homepage. To verify this, run the command gnome-system-monitor in Terminal, the GUI app "System Monitor" will launch. This extension also lets you launch the GUI app "System Monitor" (the button above "preferences" in the screenshot). – pomsky Aug 22 '18 at 18:39
