 There are reports that DisplayPort on some (possibly all) current thinkpads does not support audio. While there are adapters to convert DisplayPort to HDMI, the lack of audio makes it impossible to, for example, watch a DVD or Blu-Ray on an HDTV using the DisplayPort.

To get the NVidia drivers working for Linux I had to set the '''Graphics Device''' to '''Discrete Graphics'''. This was as of 2011-11-26 using '''driver version 290.10'''. Then run '''sudo nvidia-xconfig'''. Both TwinView and Xinerama worked fine.
