I've been looking into ways to check it, so far with no success. The gpu itself clearly works because Minecraft (a game that mostly relies on the gpu) does run slightly better than on windows, and neofetch displays it correctly, as shown on the image:
I've tried psensor, but it only displays the temperature of the gpu and not the usage (it does show the usage of the cpu, but the pre-installed system monitor already does that anyway).
I also tried with nvtop, since I read somewhere that it may also work with AMD GPUs, but it gives an error saying it couldn't find a nvidia driver, and the website doesn't show any image or sign of having tested it with AMD hardware, which leads me to assume that is not an option either.
Back when I started on linux some months ago, I used linux mint, and one of the widgets I had on the desktop displayed cpu usage, ram usage and things like that with no problem, but on the gpu usage it would just say "N/A" or something like that, so this doesn't seem like a zorin-only problem, so I also tried with the propietary amd drivers. Tried to do the amdgpu-install command after downloading the proper packages, and then it gives error and displays a few missing dependencies, which I try to install and also get an error from those
At this point, I've ran out of ideas and can't seem to find any other choice of words for online searches, does anyone have suggestions for more alternatives to see the GPU usage of an AMD GPU?
