Comment 284 for bug 973096

Yes, you're right, those NVRM messages are fine - they just say that the driver found a couple of nvidia GPUs. I was wondering if you were getting Xid errors or the 'attempted to yield the CPU in atomic mode' mentioned earlier in the thread. Your issue might still be an nvidia problem - if the nvidia module locks up the kernel it can stop any further logging - but it might be a separate issue with X or unity. If you can do so, you could try removing one of the GPUs - I vaguely recall seeing other bugs related to running two nvidia cards.
