here is my vbios file:
https://drive.google.com/open?id=0B_-jCMJSxUqBMXZobldiY2xIV00

about the later, I need to check how to do it, since I don't have any experience using bumblebee and/or different X configs..

But I can check how to do it in the next few days. Hope this can help to solve these issues!

Thanks,
