I have a Nvidia GPU, which I understand is problematic with Linux. I’ve heard this is something can happen, so I assume it’s why the “Cinnamon” process is using around 20-40% CPU resources at all times. So, how do I switch to using GPU for that? I’ve installed Nvidia drivers through the driver manager already
Edit: I figured it out, SecureBoot was turned on on the UEFI-level. I disabled it and reinstalled Mint, and it seems to work now.

- your display is plugged into the gpu? then it should just work 
- The Debian docs were really useful for me in setting up my 3090 on Debian proper. - Since Mint is downstream, maybe they will help you. 
- You can use it with secure boot enabled. See if Mint has documentation. Usually it’s just setting it up with dkms, and installing your cert to the BIOS. 
- Are you using wayland? No idea if there is cinnamon wayland. I have the same issue on gnome, the last nvidia driver that worked under wayland was 570. Since then, unfortunately the only thing that helped was going back to X. - deleted by creator
