System Information
Operating System: Arch Linux
KDE Plasma Version: 5.27.7
KDE Frameworks Version: 5.108.0
Qt Version: 5.15.10
Kernel Version: 6.4.10-arch1-1 (64-bit)
Graphics Platform: Wayland
Processors: 8 × Intel® Core™ i5-9300H CPU @ 2.40GHz
Memory: 15.3 GiB of RAM
Graphics Processor: Mesa Intel® UHD Graphics 630 + Nvidia GTX 1660 ti

Blender Version
Broken: Blender 3.6 (in wayland session)
Worked: Works in X11 session with nvidia prime.

Short description of error
In x11 i can use blender evee with nvidia-prime but in wayland i cannot use blender evee with nvidia prime. The blender window
doesn't open at all.

I have two graphics card, one integrated intel & another discrete graphics card nvidia.
Cycles works fine with nvidia in wayland session but when i try to use evee it uses integrated graphics instead of
nvidia card.

Exact steps for others to reproduce the error

  1. Login to wayland session.
  2. Open blender with nvidia-prime to run the program with nvidia. ( $ prime-run blender )
  3. Try to render using evee

Hi! I'm kinda confused about the report...

In wayland session, is your blender

  • not opening in wayland at all?
  • or can open in wayland, but crashed at eevee rendering while cycles is fine?

Intel UHD630 should by itself capable of OpenGL 4.6 which is more than enough for eevee (as long as you have enough memory).

Could you give us system information (Help > Save System Info, please upload the system info from X11 and Wayland, if blender can open) and (if crashes) crash log? You can find instructions here. Thanks!

By default, in wayland cycles uses nvidia and evee uses intel UHD 630 graphics card.
I want to make use of nvidia for both rendering engine.

Evee is super slow while using UHD 630 graphics.

For example, i can make use of nvidia card in x11 session with nvidia-prime to open blender &
render using nvidia only, without use of UHD 630 graphics card.

But for some reason, i cannot make use of nvidia card in wayland session using nvidia prime.
Blender main window doesn't show up at all.

@ChengduLittleA The user responded. I think they just want to use their GTX card with Eevee? They're saying that the Nvidia card can run Eevee on X11 using PRIME but it doesn't work with Wayland.

I don't have a laptop with hybrid graphics, nor do I use Wayland, so I don't have much to say here. Just judging by the context here I think this is less of a Blender problem and more of a Wayland and/or PRIME problem.

Humm I agree, this probably should be reported to Wayland then.

Closing as issues with GPU switching aren't something Blender can resolve, further NVIDIA support under Wayland is known to be incomplete (see comments on #103999).
