The driver is not able to find the vbios image which is required for the driver to properly enumerate the hardware. I would guess it's a platform issue. Is there a newer sbios image available for your platform? You might try that or check if there are any options in the sbios regarding the behavior of the integrated graphics when an external GPU is present. I suspect the one of the following is the problem: 1. The sbios should disable the integrated graphics when a dGPU is present, but due to a bug in the sbios or a particular sbios settings it has failed to. 2. The sbios should be providing a vbios image for the integrated graphics, but due to a bug in the sbios or a particular sbios settings it has failed to. 3. The platform uses some alternative method to provide access to the vbios image for the integrated graphics that Linux does not yet handle. I would start with an sbios update is possible. Alex
