Even when I use the MUX switch and use only the dedicated card it stills stutters badly on 2d graphics only. It's really strange.

I have a Lenovo Legion 5 Pro (Ryzen 7 5800H + RTX 3060). This happens across EVERY distro I've tried (Debian 12, Fedora 42, Mint Cinnamon, EndeavourOS, Nobara, PopOS) and EVERY browser (Firefox, Brave, Chromium).

Key symptoms:

• 2D browser games stutter badly with low framerate
• 3D WebGL browser games actually run fine (???)
• Native games run perfectly (Captain Claw via Lutris works great)
• Same exact game runs perfectly on Windows 10 on the same laptop

Someone else with an RTX 3060 tested the exact same game, seeing the same ~20W power draw, but has zero stutter issues.

Here's everything I've tried so far:

• Graphics drivers: Both nouveau and NVIDIA proprietary drivers (570.133.07), both with open and proprietary kernels
• Display settings: Tested at both 60Hz and 160Hz refresh rates
• Hardware acceleration: Enabled and disabled in all browsers
• Power modes: BIOS set to both Dynamic and Discrete graphics
• BIOS tweaks: Disabled virtualization, no power management features available in BIOS apart from that
• Performance forcing: Locked GPU clocks manually (nvidia-smi -lgc 1200,2100 and -lmc 7000,7000). Enabled persistence mode
• Added kernel parameters for power management (pcie_aspm=off acpi_osi=Linux)
• Lenovo-specific: Installed the Lenovo Legion Linux drivers from johnfanv2/LenovoLegionLinux
• NVIDIA power management: Tried enabling Nvidia dynamic boost with nvidia-powerd.service

I've monitored GPU power draw during gameplay and it hovers at 20-25W even when the light is red (performance mode) and the card is locked at P0 performance state. This is considerably lower than the ~80W it should be able to draw under load. It might not need to draw much more, but right now it's not drawing any more.

When I run the Firefox profiler to see what's happening, I can see the frame drops but there's no clear cause. And the fact that 3D browser games work fine but 2D ones stutter makes no sense to me.

If you have any idea at all I'm listening, I'm all out of ideas :(

I'd love to make Linux my daily driver, but there's an issue with 2d animations on any Linux distro I install on my laptop. Windows 10 does not have this issue. So that means like half the Internet is stuttery.

Until that is fixed, I cannot use it as my daily driver.

My brother once had an ice cream from a street vendor in Cambodia. Many locals were buying there so he figured he'd be okay. He ended up in the hospital for 2 weeks.

I don't have a hamster that folds clothes, though that is now on the list to teach my cats

I like Linux, but it isn't ready for big and complex adoption. No one can figure out why 2d browser animations stutter on my laptop, which makes browsing incredibly annoying. Imagine figuring out why your organisation directory isn't synching and it's an issue in a part of a service that has a dependency that was updated and not tested fully.

As long as this can happen, big companies won't adopt Linux.

Kid friendly houses? In this economy?

Even if I trust the flying itself, I don't trust not being detained upon entering the USA. I'm not flying there again anytime soon.

It's here: https://ostechnix.com/dual-boot-windows-and-pop-os/

In the "Configure SystemD Boot for Dual Boot" section, or maybe I misunderstand the guide?

Yeah that's true, but dual booting is harder than with most and requires tinkering with the windows boot partition, which I'm not a big fan of.

Just be sure to add only the people you want to be there. I've heard some people add others and it's a bit messy

This is honestly the only reason Linux is not my only OS. I have a laptop with an integrated and dedicated nvidia rtx3060 gpu, and Linux has trouble with the Nvidia drivers and I get stuttering in almost all games and 3d applications.

I went into a discord specialised in lenovo Legion on linux, and even they couldn't help me, though they were very helpful. My requirements aren't even insane, I just want to slice files for my 3d printer without issues and play a 2d browser game from time to time.

I'm still debugging it, it mug have to do with the power management firmware. But this is not ready for the mainstream consumer if its necessary to go this deep.

I tried Fedora but since they removed support of x11 and nvidia doesn't get along with wayland, I'm out of luck.

Was it hard to set it to always use the dedicated gpu?

Dual booting PopOS seems pretty rough though, with risks to the windows installation and bootloader

Oh, that's good to know. So I can just install x11 on my Fedora no problem whatsoever?

Only shame is that they don't recommend dual hooting with windows, which is a requirement for me

Thanks! I'm downloading nobara now, any tips to get it to work as expected?
