I am considering buying a Dell XPS 15 laptop. The laptop has a Nvidia 420m card which should work with Linux but I keep reading that the Nvidia Optimus technology isn't supported on Linux. I am not really interested in switching from Nvidia to Intel to save power but need to know that the Nvidia card will in fact work if I installed Ubuntu.
If anyone has experience using a Nvidia card with Optimus technology or even better the exact laptop in question (Dell XPS 15 with 1GB NVIDIA® GeForce® GT 420M) it would be great.
A major problem holding people back from adopting Linux is this sort of hardware issue.
I am a long term Ubuntu user and supporter who can't afford to make a mistake with a purchase like this.
I don't want to spend £500+ to find I have no graphics acceleration because Windows 7 is not an option.
