bbswitch VS nvidia-gpu-off

> How did you "power down" your nvidia card?

First I made sure X was working the way I wanted with Intel graphics. There are a handful of ways to do hybrid graphics on Linux, depending on what you want to be able to do, and how old your hardware is. The Arch wiki has some pretty good guides [1] that are helpful even if you're using a different system.

bbswitch seems to work on my system, and the interface is really simple [2]. But there's also this page on the acpi-call thing [3], which suggests that bbswitch is old and unmaintained and that newer systems do something different. From a quick scan, it looks like the Arch wiki also mentions this approach.

As far as drivers go, I know everyone likes to dump on Nvidia for their closed source mess, but in every system I've used with Nvidia hardware (desktops and laptops), I've found that the Nvidia drivers have universally been more reliable than nouveau, so that's what I use.

Not sure if you'd want to on a new computer, but you could always try to repaste and undervolt (which is enabled on tigerlake-H processors!). If you don't need to use your DGPU often, you can try to disable it with BBSwitch.

Google tells me, for ubuntu, bbswitch can be used to turn off gpu. Here's the link to its github page. I read the README file, but I'm still new to linux and i couldn't understand the following :

I think what you're looking for is bbswitch. I don't know which Optimus method you're using, but optimus-manager has bindings for it. For example. here is my config that turns it off by default if on batter power at boot:

Check: https://github.com/Bumblebee-Project/bbswitch

Try using bbswitch (you can configure it to exclusively use intel graphics)

I'm decently sure it doesn't turn off completely in Windows either. There are ways to completely disable it, but I'd say it's not worth the effort as it only saves a tiny amount of power. If you still insist on manually disabling it, check out this repo.

Already tried this https://github.com/bayasdev/nvidia-gpu-off without success.

Well then, there's this guide I know that might help you.
