Godot 4.0 (Vulkan) doesn't start if Godot 3.x (OpenGL) is running - Optimus on Linux with Bumblebee daemon

git2013vb commented 2 years ago

Godot version

4.0alpha 1

System information

Debian 11

Issue description

As stated in title. Also If I close 3.5 beta 1 then 4.0 alpha 1 start. Is like 3.5 put on hold 4.0 ps.: I have NVIDIA Optimus . So to me seems pretty much similar to https://github.com/godotengine/godot/issues/48091#issuecomment-915226816

If I open just the 4.0 the I have this error:

Godot Engine v4.0.alpha1.official.31a7ddbf8 - https://godotengine.org
Can't open bumblebee display.
ERROR: GENERAL - Message Id Number: 0 | Message Id Name: Loader Message

MESA-INTEL: warning: Ivy Bridge Vulkan support is incomplete

It let me open project manager and so on nevertheless..

Thanks

Steps to reproduce

Its seems related who have NVIDIA Optimus. Not sure 100%

Minimal reproduction project

NA

Most likely bumblebee doesn't support running both Vulkan and OpenGL contexts at the same time (or the patched version you might have, as I don't think stock bumblebee supports Vulkan at all, the project is unmaintained since 2013: https://github.com/Bumblebee-Project/Bumblebee/commits/master).

You might be able to confirm that by trying to run other OpenGL and Vulkan applications at the same time.

Its possible

Yes , I can confirm I can run Dota2 (setting on vulkan render) and Blender 3.0 (optirun - OpenGL) at same time

These issue, however, is related to Godot (3.x and another OpenGL software. Ref: https://github.com/godotengine/godot/issues/48091#issuecomment-824895551 Anyway AFIK its scheduled to be integrated in 3.5 soon. So, I guess, it will be ported in 4.0 too.. Right?
