Is it possible to use a GeForce to drive the display while installing a Radeon just as a compute device under Linux?
It should be, but this is a CUDA forum… you should be doing the oppposite… using the AMD for display and your NVIDIA for compute ;)
Sorry about that. ;)
Doing the opposite seems to be easier and more common, at least according to web searches. Anyway, unfortunately I need the NVIDIA device for OpenGL. Both companies should make it easier to run both devices in parallel…
