Re: Problem with graphic card
You likely need nomodeset kernel boot parameter which is often needed for nvidia drivers and I figured was needed for the dual types of video (instead of default kernel mode setting). I am not even sure if 13.10 install would boot without it, but I may not have waited long enough for hardware discovery the first time I booted install iso on USB stick on a laptop with Intel HD 4600/Nvidia GTX 765M graphics. It is usually best to use Ubuntu packages for nvidia drivers to make sure that everything is coordinated and updated properly, but I forget if I used Software Center or Synaptic to do that (I used nvidia-experimental-310 which is currently a 319 version). Additional Drivers will not come up with anything while running the default Intel graphics.
If you install drivers using a script directly from nvidia might be on your own figuring out how to get everything to work, especially with bumblebee, the X server, and kernel updates.
I had to do some other things to get steam to find 32-bit libs in 64-bit Ubuntu 13.10, and some launch parameters to launch steam games using optirun for nvidia graphics (I just use Intel for steam itself).
i5 650 3.2 GHz, 8 GB, nvidia GTX 550 Ti 32" 1080p | i7-4700, 8 GB, Intel HD 4600/nvidia GTX 765M 15.6" 1080p | etc.
