First off I am a new to Ubuntu with limited Linux experince but am a master in windows and I am a software engineer by trade. I want to learn Ubuntu like I know windows so decided to install it for an Embedded project I am working on.

I am triple booting Mac OSX, Windows 7 and Ubuntu 12.10. I Installed refid before ubuntu (OS X and Windows 7 were already installed). I had to use the nomodeset F6 option from the Mac Version of the x64 Ubuntu 12.10 to avoid the black screen but was able to install Ubuntu. Now when I choose Linux in refid the grub menu comes up, but I have to add nomodeset to not get the black screen again. Looking at System, Software Sorces, Additional Drivers I am using the 9600GTM card which acts as small room heater, so would like to use the 9400. (Have the same issue in Windows 7 but thats another story)

How do I make Ubuntu use the 9400 video card and disable the 9600 video card?

What video driver should I be using for the 9400? How do I download and install it.

I was going to try this (https://help.ubuntu.com/community/Ma...s_.28Compiz.29) but I don't have an etc/X11/xorg.conf file to edit so I assume I am running a diferent video card driver or somthing.

I found this page as well but it is for Ubuntu 11 so not sure how much of it applies.

I had to use the wired network connection to connect to the internet but I think I have found enough post online to fix the wireless driver.

Any help you can give would be appriciated.

Thanks

Andy
