Re: nvidia and displaylink on ubuntu
DisplayPort works fine with the NVIDIA binary driver. The other recent reports of problems with DisplayPort don't have sufficient information for us to determine what's really happening.
If you read ubootfanat's original post, you'll see that the problem is that adding a third display with the Kensington USB video adapter doesn't work. The DP connected display does come up. Unfortunately, I don't have one of these USB video adapters to test with.
