I'm running Ubuntu 10.10 with two graphic cards. I have two monitors up and running on a nVidia card and am looking to add a third monitor on a Radeon card. The third monitor appears to be recognized and can play audio, but nothing appears on the screen. A signal is being sent because the "no signal" message is not displayed. Does anyone know how to get the third monitor up and running? Below is my display information.

Thanks,
Paul
