Media Center Build - Audio Artifacts

I didn't even think about the CPU, but I would definitely not rule that out. I have no experience at all with integrated graphics, never had a CPU with that. I don't know if it's possible that the CPU is doing the desktop rendering, which might explain your issues.

Isn't it typical, we keep looking for complicated reasons for the issue and then it turns out to be something simple.

But if you had a laptop without this problem, and it also had Nvidia, then it might only be certain models that have some issues with the nvidia power management.

So after a bit of searching, there is supposedly a command that should do this. Try it to see if it changes it to maximum performance:

Code:

nvidia-settings -a '[gpu:0]/GpuPowerMizerMode=1'

If that successfully changes it to maximum performance, then I can help you implement it as part of the startup.

systemd does not look at rc.local at all, and unless Mint has some compatibility tools to parse rc.local, then that file is completely ignored.

I'm not familiar with startup applications for Mint. When you tried creating one, did you use sudo in it? You should not use sudo for this command, same when you are simply running it in the terminal.

My wife has a laptop with Mint and an Nvidia gpu, so I found the startup application in mint and it worked on her laptop. Just simply having it run the command (no sudo of course).

It changes back on its own? That seems to defeat the whole purpose of being able to change settings. Well, we could make a script that checks the value of powermizer, and switches it to performance if it is at any other value.

Or for an even simpler brute-force style solution. A simple script that sets it to performance every second:

Code:

#! /bin/bash
while :
do
    nvidia-settings -a '[gpu:0]/GpuPowerMizerMode=1'
    sleep 1
done

You can put that into a text file, ensure it is executable, and then create a startup application to run this script. You could also simply run the script manually after starting the system.

I don't see why this shouldn't work, unless changing powermizer setting continually will cause some performance loss. If you keep this running, but experience some loss of performance, then we can move away from this brute force approach. But hopefully this simple solution is sufficient.
