    I've tried a few variations for the "server layout" section but so far every time I add that section and restart I get a splash screen on the left (onboard video) screen and then both monitors report no signal
    oddly when I start up without the server layout section I get s splash screen on the left screen then the right screen comes up

    I hope someone can help this is about ready to drive me back to windows because I am incredibly more productive with two screens.

    Thank you

    I stumbled across a discussion awhile ago about two cards, three monitors. Perhaps it might be helpful?

    Just an interested observer, I have no experience with such setups. Sorry I can not provide direct assistance.
