VK_ERROR_INCOMPATIBLE_DRIVER

[franalbani]

How should I continue debugging this?

$ ./cyberether

Build instructions went fine.

Nothing obvious comes to my mind. Are you launching CyberEther from a terminal that has a display attached to it? You can check this with echo $DISPLAY.

Hi Luigi!

Yes.

I can also share sudo coredumpctl debug:

I had the same error on macOS Ventura (13.6.6):

I could fix the error by running brew install molten-vk vulkan-tools so it seems that at least one of the packages was missing.
