Originally I wanted to make a live CD with this... However I gave up on that.

So Is there a way to do this, have ubuntu figure out which card is loaded, before loading a driver. Or... How could I create a script to load at boot to "| grep pci... etc" and print for variable to run "activate_AMD.sh" or "activate_NV.sh" etc...

Ubuntu automatically detects which GPU is installed in your machine. If you want a script to switch between Nvida and Intel drivers I've found one you can modify here: bauca/graphics-switcher

It will require the program glxinfo which you can get by installing:

sudo apt install mesa-utils

One key function in the bash script that will interest you is this one:

function CheckForCurrentVideoCardInUse {
    local _VIDEO_CARD=`glxinfo|egrep "OpenGL vendor|OpenGL renderer*"`
    if [[ $_VIDEO_CARD == *"NVIDIA"* && $_VIDEO_CARD == *"GeForce"* ]]; then
        CURRENT_VIDEO_CARD="NVIDIA"
    elif [[ $_VIDEO_CARD == *"Intel"* ]]; then
        CURRENT_VIDEO_CARD="INTEL"
    else
        ErrorHandler
    fi
}
