I have a Dell XPS L702X laptop which has an Intel and Nvidia card built into it. In Windows the laptop will switch between the two depending on power usage, so I can run the Intel card when I want better battery and the Nvidia card for games or general plugged-in use. In Windows 7 it works great (other than a weird white balance thing sometimes with the Intel card when it activates).
I install Ubuntu 11.10, and I had to install the Nvidia drivers after it was installed. When Ubuntu boots it uses the Nvidia drivers. Is there a way that I can choose to switch between the two at boot? For most things I don't need the 3D drivers to run and it seems to suck the battery as well as run the fan constantly, so I hate to run in Linux for long periods of time.
Since I don't think there is a way to get this to work like Windows, what's my best option? I don't mind having to reboot if that is what it takes.
