App not working on ubuntu 20.04.02 LTS

[silencify]

I have run the command. But the applet is not showing up. I was using it in the Ubuntu 18.04 and it was working fine. This is one of the best applet I have used. Thanks. My system is:

OS Name - Ubuntu 20.04.2 LTS OS Type - 64-bit GNOME Version - 3.36.8 Windowing System X11

I can confirm that. Here is what I can find in system logs when enable the extensions:

This seems to be a bug in the code that breaks the extension when Wayland's enabled. I was able to get the extension to work in 20.04 by disabling Wayland, rebooting, and then checking out the repo and running make install, followed by a alt+f2 rto reload.

That's not an ideal solution, but that's one workaround for now.

I'm also using Ubuntu 20.04 LTS, I installed libgtop2-dev package and it fixed this error at all

FYI : after installing required libraries, logout and back in ( especially if you are using wayland ; "r" might work on X11 ) to properly restart gnome-shell.

Same here.

On Ubuntu 22.04.1 under Wayland installing libgtop2-dev did the trick:

sudo apt-get install gir1.2-gtop-2.0 gir1.2-nm-1.0 gir1.2-clutter-1.0 gnome-system-monitor gir1.2-gtop-2.0 gir1.2-nm-1.0 gir1.2-clutter-1.0 gnome-system-monitor gir1.2-gtop-2.0 gir1.2-nm-1.0 gnome-system-monitor libgtop2-dev

apt install libgtop2-dev worked under Pop 22.04 with x11, using mgalgs's fork.
