Software to View GPU Usage and VRAM Usage on Nouveau
PublicNuisance Jun 25, 2020
On most of my systems I have an AMD GPU and would use Radeontop to view the GPU usage and VRAM usage. On my Trisquel systems I have Nvidia GPUs using the Nouveau drivers so that doesn't work. Can anybody recommend me software that would list the GPU and VRAM usage for GPUs using Nouveau ? The cards specifially are a GT 730 and a Quadro NVS 140M if that matters. Thanks in advance.

I haven't tested it since I don't use Nouveau, but have you tried MangoHud? I use it with the binary driver and with amdgpu and it works great.

That's a really good idea I hadn't thought of. I use MangoHud on my main system and it should work on the others as well.

We can use GL-Z :

I just gave GL-Z a try. I like the idea and layout of it but on both of my systems I tested it on the GPU usage would just stay at 0% and I couldn't find any info on VRAM being used. It showed the total amount of the card but not current usage. One of my systems had a GT 730 and the other my 5700XT, both using Mesa drivers. Maybe GL-Z doesn't like Mesa ? or maybe i'm doing somethign wrong or looking in the wrong place.

The latest stable GL-Z is not able to works with latest Radeon RX. But the following tool, based on GL-Z can works:

Sorry for the late reply but I finally got around to trying your new link. I tried it on all of my systems and on my Nouveau systems running Trisquel it only showed me GPU temps not usage. On my system that uses the 5700XT it did work just as in your screenshot. On that system however I can use Radeontop. Looking at the screenshots on the link you provided I think that this isn't a glitch but expected behavior as on their test with a GTX 960 using Nouveau drivers they only showed temps not usage as well. I think Mangohud/Goverlay combo is still my best bet on Nouveau. Thank you for the effort regardless !
