I have 2 VGAs: nvidia 8500gt and intel GMA950

Some time ago my pc didn't boot up with the NV card set as default in the BIOS configuration. I solved it by blacklisting intel_agp module, but now I want to use both cards.

Is that possible?

More info: If I allow the intel_agp module to load, then the pc hangs up at boot (with NV set as default in BIOS) And if I set the intel card as default, I cant see anything (not grub, not xsplash) until GDM loads (with the main screen plugged to the nv card)

Hope you can help me!

Thank you!
