Hi, I have recently updated to yosemite from a pretty flawless mavericks system. I have everything working that I need (no iMessage, or bluetooth- have dongle for that), except for the fact that only one of my two gtx770 4gb work. I used to have both my monitors fed into the top card, but if I use that now only the left will show during boot, and will only display everything at low res with laggy mouse and the dock is not see through but white. Looking at system prefs this is what I see.

So the bottom card is naturally recognised and the top card is being seen as nvidia and er that's where i'm stuck.

below is my chameleon playlist

Have you tried installing the Nvidia web drivers?
 
hey slim, I'm not able to, I downloaded them and got this message when i went to install them-

Mac OS X version 10.10.3 (14D136) is not supported with this package. Please see NVIDIA’s website for further driver information.
 
update managed to install the drivers using WebDriver-346.01.02f04

it hasn't made any difference though.
 
The preference pane is showing Web drivers ticked rather than osx, do I still need to run that flag? I did look through that thread but didn't see anything related to my issue of one card working one not.
