msci-thesis VS optimus-manager

That was partially my "fault", as some of the research which led to Plundervolt was the subject of my Master's thesis. Funnily enough, this means I know a bit about what you'd need on Linux. There's a tool called intel-undervolt which should allow you to configure profiles, though you might need a custom shell script or something to automatically toggle between profiles based on whether the device is plugged in or not. The Linux kernel itself has decent P-state management by default as it relies on the CPU to tell it what P-state to use, but this is based on not undervolting. You'll need to disable this default P-state management by specifying intel_pstate=disable to the kernel on boot; you can edit your bootloader (e.g. GRUB) config to do this for you.

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.

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!
