Did changing the bios settings help?

I have come across some more info - it is an issue with optimus which is 
a technology to allow switching between lower power usage intel graphics 
and higher performing nvidia graphics. I didn't hear any certainty about 
turning it off in bios but there is a record of linux not supporting it. 
A project called bumblebee targets getting support on linux.

The two busid's reflect the intel and nvidia devices - did you try 
removing nvidia and using only the intel settings?
