From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Lenovo Dual GPU Laptop on Linux (lemm.ee)

submitted 11 months ago by [email protected] to c/[email protected]

10 comments fedilink hide all child comments

Hi,

I want to buy a laptop for working and very light gaming on to go. I'm currently looking for Lenovo IdeaPad Gaming 3 with AMD CPU and NVIDIA GPU. I'm going to use Fedora or Arch Linux with i3wm. The problem is I'm not sure if dual gpu setup is going to work or not. All i want to use igpu for all tasks until more power needed, then it needs to switch automatically to dgpu

Is this possible if so is there any good guide about it?

Thanks

I have similar laptop currently and I have it set up exactly as you want. I'm on Void Linux with KDE Wayland, but I was using Fedora few months ago and I remember it working correctly too. Wayland uses integrated GPU by default, so in case I want some program to use dedicated GPU, there's handy script to do that (it just sets few env variables).

I think it should be quite easy to set X with i3 to use integrated GPU, just like Wayland does.

I prefer nvidia-xrun over PRIME

I'm not entirely sure, but that would mean that the laptop's display would have to be connected to both the integrated graphics unit and the dedicated graphics chip. I suspect that this will not be the case with most laptops.

I think most modern laptops output to display via integrated GPU even if it's dedicated GPU doing the work. I know there are laptops with much chips that let user select which GPU is directly connected to display, but I guess those are mostly high-end models.

I have the intel/nvidia 2080q on my lenovo 17inch legion. Nvidia works on my Nixos with wayland/hyprland. Using both as well to save batter just have to activate nvidia prime with a command.

Off topic a bit, but how is the Nvidia + Wayland experience?

Are the horror stories true? Do you use multiple monitors?

Its fine for me?
