"This is all very good, the more mistakes I make the more I learn" he repeated to himself over and over again like wild eyed crazy man pacing up and down the lost halls of a forgotten mental asylum. For a while there I had something working. It was really cool, I was happy and free, my hair flowing behind me blown up by the magical breeze emanating from the cooling fan of my computer tower. I'd managed to dual boot Kali Linux along side Windows. The problem I had was that I was not able to get the two screens working as a single display. That is to say I was seeing double. I read the instructions on this page http://docs.kali.org/general-use/install-nvidia-drivers-on-kali-linux in an attempt to solve that problem. I knew it was a graphics card driver problem because when I went to the 'displays' section of the system settings the display showed as unknown and only showed one rather than two. After following the instructions to reboot I now get [...] Waiting for /dev to be fully populated...udevd[512]: specified group 'pcscd' unknown during the boot into Kali-Linux. And that's where the computer stays. Any ideas? Scott.
