Hard disk led simulator on screen

[Gingalone]

I have a Dell XPS laptop (Ubuntu 18.04) which doesn't have a HD activity led on it. I saw on the web there are some on-screen HD led simulator for Windows: is there something of the like for Linux/Ubuntu?
Just a simple little flashing light somewhere on screen... I really would like that!
Thank you for suggestions.

Possibly give conky a try:
How To Install and Use Conky in Ubuntu Linux

You could probably make a very minimal setup that just showed a "hard drive active" display of some sort, but I'd explore the options with a basic install first so you can learn the system and see what it can do.

See 'gkrellm'.

Ubuntu MATE's System Monitor has a HD activity indicator available, and, for that matter, CapsLock and NumLock.

No HD LED shows the difference between read and write operations. I set it to red for read, and white for write, and have a better idea of what's going on when the HD light comes on.

Can that be installed in the Cinnamon DE?

Thanks a lot for suggestions; then I installed the package mate-system-monitor_1.20.2-1_amd64.deb and tried it:

:~$ mate-system-monitor

** (mate-system-monitor:23355): WARNING **: 14:39:56.203: SELinux was found but is not enabled.

I/O warning : failed to load external entity "/usr/share/mate-about/mate-version.xml"

and then I get a window of the classic normal System Monitor (no HD monitor option)
What about?
