optimus-manager VS bbswitch

See the discussion on Github at https://github.com/Askannz/optimus-manager/issues/543

Read: NVIDIA Optimus AND optimus-manager documentation thoroughly.

Use Nvidia to render everything. You can easily do this with programs such as Optimus Manager or Envycontrol (I recommend the latter if you're on wayland). You can set it so that when you're on charger, laptop boots with the Nvidia (dedicated) mode and when you're on battery it boots with integrated mode (if you do this, read the wiki about Nvidia as you're going to possibly experience nvidia-related issues).

I have installed optimus-manager few hours back(I'm in NVIDIA propitiatory). Read this https://github.com/Askannz/optimus-manager/wiki/A-guide--to-power-management-options and came to understand that manual configuration is necessary for turning off the nvidia card completely. Tried : Configuration 1 : dynamic power management inside the NVIDIA driver (Runtime D3 power management) Configuration 4 : acpi_call. But none is completely turning off the NVIDIA card even though I ran optimus-manager --switch integrated (applicable to only config 4).

What you meant was optimus-manager program and you should look at https://github.com/Askannz/optimus-manager for instructions with that method of using Nvidia Optimus, but you should also look at instructions for other methods for Nvidia Optimus too, especially PRIME-Render Offload one, because you can find important things for power management at https://wiki.archlinux.org/title/PRIME#PCI-Express\_Runtime\_D3\_(RTD3)\_Power\_Management , because you have a Turing GPU and Tiger Lake CPU, and method for Nvidia Optimus you mentioned and want to use is best supported with gdm, sddm and lightdm display managers and you may want to look at other Nvidia Optimus methods.

-Refer to this: https://github.com/Askannz/optimus-manager for help with other display managers or issues

Just asking because I wanted to give some advice and it would be different between a desktop and laptop. There are some options to manager graphics through a gui like optimus manager. PopOS also comes with some extensions to manage it out of the box. You can also look at using Lutris for gaming, you can use it to make every game launch with your discrete gpu by default.

Hello, I am a newbie to Intel-nvidia-hybrid laptop. My issue is that I cannot use Nvidia dGPU for my favourite apps. I have tried Optimus Manager and Envycontrol but both of them breaks my system. I am using HP Envy laptop with Nvidia gtx 1650 ti maxq. Thank you!

> 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:

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