-<p>The goal is to get <a href="http://www.ubuntu.com/">Ubuntu 13.10</a> (Desktop version) running on the integrated Intel HD 3000 graphics chip and use the available GTX 660i as a dedicated CUDA device. Googling around brings up various guides, e.g. from <a href="http://www.r-tutor.com/gpu-computing/cuda-installation/cuda5.5-ubuntu">RTutorial</a> for Ubuntu 12.10 and one on <a href="http://askubuntu.com/questions/380609/anyone-has-successfully-installed-cuda-5-5-on-ubuntu-13-10-64-bit">AskUbuntu</a> specifically for Ubuntu 13.10. These guides advocate downloading the newest driver and cuda toolkit from nvidias website and running the installation process manually. Doing so however broke my Xorg setup: After logging in wiht lightdm, the screen stays black. Investigating this issue (i.e. looking into /var/log/Xorg.0.log), it seems that with the <em>current</em> nvidia provided drivers (that is version 331.??) intel's libGLX.so gets overwritten and thus unity can not start. Looking around, <a href="http://mauricio-matera.blogspot.com.ar/2013/10/configuring-cuda-in-ubuntu-1304.html">Juan Mauricio Matera</a> already provided a simple fix for that. It seems that other people also stumbled over this problem, e.g. see this question on <a href="http://askubuntu.com/questions/355731/use-integrated-intel-graphic-card-for-display-and-tesla-for-cuda?rq=1">AskUbuntu</a>.
