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.

Distro suggestions for a dual-GPU Lenovo laptop? (lemmy.ml)

submitted 1 day ago by [email protected] to c/[email protected]

I'm a long-time Linux user but for the past few years my main laptop - a Lenovo Legion 5 with both AMD iGPU and Nvidia dGPU - has been on Win10. I'd like to upgrade and am looking for suggestions for distros and configurations. I've mainly used Debian-based distros in the past but am not particular. Here are my main concerns:

I will likely still need to run Windows in a VM for a few corporate applications that won't run in Linux (according to some teammates who have tried).
I do a lot of work in Figma and haven't tried it at all in Linux, but I know for sure it needs GPU acceleration. It seems like I'd have to choose between the following:
- just running in a browser window and (somehow) assigning the dGPU to that browser
- the above, but using the unofficial Linux electron-based figma app
- try running the Windows app in Linux
- putting Linux on the iGPU and passing the dGPU through to a Windows VM for this
I also do a fair amount of local LLM work. I would prefer to do this in Linux with the dGPU, but again I could pass the dGPU through to a Windows VPN and then do it in WSL2 in Windows (which seems a little janky)
I don't want to dual-boot

Does anyone have any thoughts/suggestions on this? I haven't tried GPU-switching in Linux for a long time and had poor success in the past. Am I better off leaving both GPUs accessible in Linux, or passing one through for the Windows VM?

One thing you probably need to figure out first: how are the dgpu and igpu connected to each other, and then which ports are connected to which gpu.

Everyone does funky shit with this, and you'll sometimes have dgpus that require the igpu to do anything, or cases where the internal panel is only hooked up to the igpu (or only the dgpu), and the hdmi and display port and so on can be any damn thing.

So uh, before you get too deep in planning what gets which gpu, you probably need to see if the outputs you need support what you want to do.

Yes, that's a good point, I think the thunderbolt out only works on the iGPU, so I'm assuming that to get dual external monitors (HDMI and usb-c) the bare metal OS (Linux) will have to be running at least the iGPU.

I guess that also begs the question: X or Wayland in this scenario?

[–] [email protected] 1 points 1 day ago

I'll admit to having no opinion on windowing systems.

If the distro ships with X, I use X, and if it ships with Wayland, I use Wayland.

I'd honestly probably not be able tell you which systems I've been using use one or the other, and that's a good thing: if you can't tell, then it probably doesn't matter anymore.
