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.
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.
