This likely has nothing to do with GA107 and everything to do with the fact that the GPU is in the dock. Also, this by itself doesn't fix a kernel bug. It disables DRM format modifiers in Mesa and that's likely having knock-on effects with compositors and GPUs vanishing. Please file a Mesa issue. We should sort it out in userspace.
