cuda与optimus只是访问gpgpu [英] cuda with optimus just to access gpgpu

问题描述

我有戴尔XPS L502与Nvidia 525M显卡。我现在只对使用卡的gpgpu功能感兴趣。

I have a Dell XPS L502 with the Nvidia 525M graphics card. I am only interested in using the gpgpu capabilities of the card for now.

我安装了Ubuntu 12.04作为与机器附带的Windows 7的双引导，并按照几个安装程序从Nvidia安装CUDA驱动程序和开发工具包安装Ubuntu）。在所有情况下，显示器降至640x480分辨率。最好我可以确定这与Optimus技术和Linux有关。我尝试大黄蜂没有效果。

I installed Ubuntu 12.04 as a dual boot with the Windows 7 that came with the machine and followed several installation procedures for installing the CUDA driver and developer kit from Nvidia ( many re-installs of Ubuntu ). In all cases the display drops to 640x480 resolution. Best I can determine this has something to do with Optimus technology and Linux. I tried Bumblebee to no avail.

我真的不在乎使用NVidia卡来驱动显示器。有没有什么办法，我可以只安装NVidia驱动程序，以便程序可以使用显卡的CUDA功能，我仍然在显示器上获得全分辨率。

I really don't care about using the NVidia card to drive the display. Is there any way that I can just install the NVidia drivers so that a program can use the CUDA capabilities of the graphics card and I still get the full resolution on the display?

推荐答案

随着新版本的CUDA 5，安装指南，你只有一个文件，安装驱动程序，工具包和sdk（甚至nvidia nsight）。有一件事让我注意到，你在安装过程中也有 optimus 选项。

With the new release of CUDA 5 the, comes the installation guide, there you have just one file that installs drivers, toolkit and sdk (even nvidia nsight). And one thing that got my attention is that you also have optimus options in the installation process.

我也有Alienware M14x和i理解你的问题，但我也想让司机为我工作，所以我没有尝试太难。

I also have and Alienware M14x, and i understand your problem, but i also wanted the drivers to work for me, so i didn't try too hard on that.
