Answer 1

Such a question is very (OS version / GPU hardware / graphics driver) specific as solution varies

If you install https://extensions.gnome.org/extension/120/system-monitor/

there is a GPU setting in Preferences -> DisplayStyle -> both

________________ Only Nvidia GPUs supported so far ________________

Currently on 19.04 here is an error with above install here is work around ... download https://github.com/paradoxxxzero/gnome-shell-system-monitor-applet/archive/master.zip

which will give you ~/downloaddir/gnome-shell-system-monitor-applet-master/system-monitor@paradoxxx.zero.gmail.com/

cp -rp ~/downloaddir/gnome-shell-system-monitor-applet-master/system-monitor@paradoxxx.zero.gmail.com  ~/.local/share/gnome-shell/extensions

so it results in

ls -la ~/.local/share/gnome-shell/extensions/system-monitor@paradoxxx.zero.gmail.com/

install upstream packages

sudo apt-get install chrome-gnome-shell    
sudo apt-get install gir1.2-gtop-2.0 gir1.2-networkmanager-1.0  gir1.2-clutter-1.0
