So I have a jm with an 860m in it. I've managed to get everything working now except for the nvidia gpu. When I try to install the web driver and add the statement in to use it. I'll go into a reboot cycle until I pass the flag for nvidia to VESA. The reading I've done seems to say that this is because the 860m is an optimus(sp) card. But the reading I've done would have suggested that yours would have been too. Any chance someone could elaborate on this?
