What I did was open a text only terminal with Ctrl-Alt-F3 and requested it to restart display-manager. You won't see this yet if you don't sort of restart. On previous attempts I had already restarted and could just issue some CLI voodoo (actually the enable step from the TLDR, though substituting info indicated enable would be needed) to have the graphs magically appear: What worked was (instead of gnome-tweaks, which sounds Kev-ish): gnome-extensions enable discovered this from the author's README (where they are calling the tool an "applet"):Įnable it with gnome-tweak-tool or gnome-shell-extension-tool playing with that command (because writing someone else's email sounds like an exfiltration risk). I tried logging out and in and even rebooted all to no effect. Sudo apt-get install gnome-shell-extension-system-monitor

I've just refined this on my third Ubuntu 20.04, and did it on 18.04 way back in 2018/2019. gnome-extensions enable Sort of restart, but as Tully says, only gnome shell needs to.sudo apt-get install gnome-shell-extension-system-monitor.
