Re: [gentoo-user] Nvidia and optimus
Need some help (taking the topic that is about this): already build bumblebee and implemented everything (runned glxgears with optirun and things gone okay). However, I'm with some problems to play some games, like Shatter and Anomaly, that has 32-bit only versions (my ARCH=~amd64).

Unless someone knows specifically For optirun you don't need any particular 32-bit dependencies, but you need the 32-bit dependencies for the games. The best way to find the dependencies is to install the game and run ldd on the binary. E.g.: ldd /opt/anomaly/anomaly (If that's the name of its binary.) Then find the packages to which the libraries in the output belong and install the corresponding app-emulation/emul-linux-x86-* packages resp. put them into the DEPENDS array of your ebuild. Heiko
Re: [gentoo-user] Nvidia and optimus
I'd like to use the internal card most of the time since I don't care about 3D acceleration but I do care alot about power saving. When using an external monitor I'd like to use the NVidia card. Currently my solution is to reboot and change bios settings, being able to switch at runtime would be a real enhancement for me. Is this possible? Yes, install xrandr/xinerama. P.S. On top of that, this laptop has only a year or so left before I replace it, and I know now to avoid Optimus entirely in the future. Will probably be impossible in the future if you buy anything with a discrete card (even a crap one, for multi-monitor). New laptops are shipping without an HDMI multiplexer like Christian's has.
Re: [gentoo-user] Nvidia and optimus
What would you consider better support? The way it works currently is how it's working with MS Windows (as provided by NVidia). What I mean by better support is easy install and configuration. In the Windows I just install the driver and the driver is responsible for offloading or switching the chips. I spent a couple of hours to configure it and gave up, because it is not easy to configure or even easy to troubleshoot. A single GPU makes things simpler, but being able to have the best of both options: 1) Intel = low power = long battery life 2) Nvidia = good quality 3D, but shorter battery life The NVidia chip is actually switched off when not being used. (Or if not, I wouldn't notice as the battery life is significantly better after installing bumblebee and running the bumblebee service.) Thats right for the current setup, but it is possible to have a laptop with a powerful Intel GPU, right?
Re: [gentoo-user] Nvidia and optimus
You need bumblebee. Otherwise it's not possible to use the Nvidia Optimus chip. I think that it is possible, or supposed to be possible! The gentoo wiki says that Nvidia drivers are now supporting the optimus, so it is called native optimus support I just waned to use optimus without that, but it seem the it is not easy! It's not possible, because the Nvidia Optimus chip isn't a full featured graphics card, and doesn't write directly to the screen. Joost already explained it pretty well. Exactly, that is why the Nvidia driver is using the xrandr for offloading the tasks.

But those don't come close to the specs NVidia and ATI put into the real GPUs. Your right but I am not gonna need those specs for a laptop.
