in order to make TestGPUInfo work properly and return something like:<br>
<br>
"<br>
There is 1 GPU(s).<br>
GPU 0:<br>
dedicated VRAM=512 MB<br>
dedicated RAM=0 MB<br>
shared RAM=0 MB<br>

1. With a Windows machine, you need to install the DirectX SDK.<br>
<br>
It have been tested on VTKEdge with the DirectX SDK from August 2008:<br>

<br>
And you can find the latest Direct X SDK from February 2010 here:<br>

<br>
<br>
2. With a Linux machine with an nVidia card, with an nVidia<br>
proprietary driver, you need to install the NVCtrl library (It gives<br>
access to the NV-CONTROL X extension) and set VTK_USE_NVCONTROL to ON<br>
in your dashboard script:<br>
<br>
* If it is already installed on your system, you can find the library<br>
libXNVCtrl.a in /usr/lib/ and the header files NVCtrlLib.h and<br>
NVCtrl.h in /usr/include/NVCtrl/. On Ubuntu, those files are provided<br>
by the package "nvidia-settings".<br>
* You can also get them from the source package of nvidia-settings<br>
from <a href="ftp://download.nvidia.com/XFree86/nvidia-settings/" target="_blank">ftp://download.nvidia.com/XFree86/nvidia-settings/</a>. With the<br>
source package, all the relevant files are in src/libXNVCtrl/. Make<br>
sure to download a version of nvidia-settings equal or greater to<br>
177.82 to avoid any license issue. (on August 25 2008, nVidia<br>
acknowledged that there is a mistake in the license of the NVCtrl<br>
library prior to 177.82, it should be MIT-X11 / BSD instead of GPL,<br>
only the nvidia-settings application is covered by the GPL, not the<br>
NVCtrl library:<br>

<br>
3. There is nothing special to change on Macs.<br>
<br>
What I just wrote is pretty much what it is the VTKEdge FAQ as the<br>
GPUInfo feature was moved from VTKEdge to VTK:<br>
