[Solved]Framework 16 - Dedicated AMD GPU is activated very often

I have a Framework 16 laptop with a:

• AMD Ryzen 9 7940 HS CPU with Radeon 780M (integrated) GPU

• AMD Radeon RX 7700S dedicated GPU

These GPU units are both supported by the amdgpu driver which is loaded correctly at boot.
Installed are mesa, lib32-mesa, vulkan-radeon, lib32-vulkan-radeon

I use Gnome on Wayland.
I have switcheroo-control installed and it works.

I experience small delays when opening most applications and the culprit seems waking of the dedicated GPU for small amounts of time looking at the output of: /sys/class/drm/card1/device/power/runtime_status in a loop script.

I found in the Wiki this remark, but that didn't help, and it seems NVIDIA only anyway:

/etc/environment

__EGL_VENDOR_LIBRARY_FILENAMES=/usr/share/glvnd/egl_vendor.d/50_mesa.json
__GLX_VENDOR_LIBRARY_NAME=mesa

I tried software rendering as per this wiki remark, but that was very slow and the gnome-session crashed:

/etc/environment

MESA_LOADER_DRIVER_OVERRIDE=kms_swrast

When I load applications from the terminal with DRI_PRIME=0 application (0 is my iGPU, checked that) the same happens. Always triggering a wakeup from the dGPU with a small delay.

So, does anybody know what to try next or even has a solution for this? Not only are the delays very annoying, but it also drains the battery. I only want to use the dedicated GPU when gaming, rendering GNOME (shell) is for the iGPU.

EDIT: I'll leave seth's suggestion here so it can be seen by non-members:

Try "GSK_RENDERER=ngl" or "GSK_RENDERER=gl"?

Thanks, but that's not a fix. It just activates the dedicated GPU for a long time draining battery.
It works for the delays though.

Edit: above this is for the first link you posted (you edited it).
I will try the next solution and be back.

EDIT2: I now see that is a different problem. Very confusing. The thing you added fixed it though, see below in my final post.

Ok doing this:

/etc/environment

GSK_RENDERER=ngl

fixed it indeed as per https://bbs.archlinux.org/viewtopic.php … 1#p2211391.
Thank you very much.
