Having trouble finding a hardware monitor. I tried GNOME's system-monitor, but it doesn't show most of the possible info; I only get the CPU temp. My system has the MSI Gaming Edge AC with a Sapphire Radeon RX Vega 64 Nitro+.
I like to use
sudo apt install conky
Conky is a light weight system monitor that let's you pick and choose system information and your own information and place it on the same window you can move anywhere:
My design is about four years out-of-date and not nearly as fancy as "modern"
It's come to my attention some people (or everyone?) is having problems with conky under version 18.04. In which case I found this blog:
I had upgraded my 16.04 to 18.04 last year and don't recall any problems with conky. That said I rarely use 18.04 and prefer the stability and comfort of 16.04.6 LTS.
