Hybrid Graphics RTX 4060 with Ryzen 7 7735hs stuck at boot

So I have a lenovo legion 5 15ARP8 laptop with advanced optimus and an nvidia rtx 4060 with ryzen 7 7735hs. I made a dual boot with arch linux and setup the sddm and wayland, but everything breaks when i change to igpu, specifically when trying to change graphics mode to dynamic in my bios which is basically hybrid mode after switching to hybrid using envycontrol. But normally it breaks everytime i change to dynamic graphics. this is the output from journalctl:

for more clarity.

Setup

    Dual-boot: Arch Linux (primary OS) + Windows.

    Display Manager: SDDM.

    Display Server: Wayland (tried Xorg too).

    Tools: envycontrol for GPU switching.

When I enable Dynamic Graphics (Hybrid Mode) in the BIOS:

    The system fails to boot properly (stuck at /dev/nvme0n1p3 clean, or freezes at a part where an underscore appears in the far left corner).

    Switching to iGPU-only mode also breaks the display.

    Works fine in dGPU-only mode.

Steps to Reproduce:

    Enable "Dynamic Graphics" in BIOS.

    Use envycontrol -s hybrid (envycontrol is in a virtual environment ).

    Reboot then system hangs or fails to start the display manager.

Any help is appreciated!

https://wiki.archlinux.org/title/Dual_b … ibernation

Disable windows fast startup and hibernation, then reboot both OSes twice to ensure the changes stuck.

Also read the rest of that wiki page.

I understand but in the wiki it talks about the case of a dual boot in the same drive as windows, my Linux is installed in my second ssd drive which was empty. Still should I check windows settings that could disrupt changes in Linux?

Re: Hybrid Graphics RTX 4060 with Ryzen 7 7735hs stuck at boot

Yes, windows fast startup/hibernation can affect hardware directly.
An infamous example is that of network cards that are powered down (due to power saving options) when hibernating windows and are impossible to re-activate from linux.
