Hi. I have a CentoOS machine with 2 GeForce GTX 285s. I am only able to get one of the cards to work. I have swapped cards and the card in the top slot works each time, so I’m pretty sure the cards are okay. I have attached a monitor to both cards, but the second card, again, doesn’t work. Any clues about how I might get the second card going? Are there things I should try? I have read all about getting multiple monitors going with the two cards, but I don’t think I am there yet. Right now I’d just like to be able to run CUDA kernels on both cards. I have the output of deviceQuery below. I also included the output of scanpci.-v.
