I'm hoping to harness some of this awesome compute power for OpenCV and perhaps even Folding at Home. I've already started playing with OpenGL courtesy of this excellent tutorial ( <a href="http://www.opengl-tutorial.org/" target="_blank">http://www.opengl-tutorial.org/</a> ), which has been most interesting and fun. Plus it's given me a chance to exercise my C (not C++!) chops..<br></div><div><br></div><div>So my first problemo was that I was running the proprietary Nvidia drivers for my current $70 video card, which according to lspci is:</div><div><br></div><div>04:00.0 VGA compatible controller: NVIDIA Corporation GF119 [GeForce GT 610] (rev a1)</div><div><br></div><div>The proprietary drivers were in the nvidia-legacy-390xx-driver package. Since the new card is an AMD, I very much doubted that the nvidia proprietary drivers would even allow me to bring up the desktop.

They were failing on the GLFW initialize. I found that glxinfo(1) was also failing, claiming it couldn't init GLX properly. After some random duck-duck-go ing I found that my problem was the openGL eXtensions. The final clue was that the nvidia drivers replace libgl.so.0 with a proprietary version. I installed "libgl1" ("vendor-neutral GL dispatch library") and rebooted. At that point, both glxinfo(1) and my tutorials started working again. Phew!</div><div><br></div><div>Piglet is now just marginally noisier than she was with the old card -- this one has two fans in it, so I am up to around 7 fans total in her.
