1- I am trying to install an nvidia card to use with the display and radeon for calculations. However once I install the nvidia driver, the clinfo does not show Radeon anymore. (I didnt try/check with nouveau driver ... )
So, is it because X is not running on this card? If yes, is there any instructions on what to do to run a dummy X on it?
Does this work better on Windows? or would it have made any difference if both cards were from AMD?
