I tried turning off nVidia and using intel. The result was a blank screen. I know other people had the same bug which was something to do with reprobing lvds?! I saw patches go by and every time I tried one the results were the same. fail. I was actually about to post a bug report to the intel (i915) people about it. I tried to work out how to get optimus to work. After trying several different sets of instructions I never found a working configuration and put it aside. I never used to use opengl but lately my pcb software has adopted it so my needs changed. I will get back to you with more results on this matter after I get the newer kernel up.
