I just installed Ubuntu to try it out and get to use some free CFD programs I like it thus far, except for my second, smaller monitor mocking my main unit. Not used to using script based commands yet (other than dxdiag and ipconfig ) Should nView or whatever it is called that nvidia has for multi monitor support work? (yes I have an nvidia card)

 

I was running Ubuntu forever on my laptop, and mine did the same thing when I plugged in a second monitor. I just had to install the correct video drivers and run the ati control panel then change the settings through there.
