No video is output to screen when using Nvidia GPU. Must switch to VT and uninstall nvidia drivers, restart lightdm service, reinstall nvidia drivers, disable Nvidia GPU from nvidia-settings and reboot. On Intel GPU, it works fine. The nvidia-prime setup worked well on kernel 3.12, but on upgrade to kernel 3.13 it stopped working. Used nvidia-331-updates and nvidia-331, same issue with both. Also installed nvidia-331-updates-uvm/nvidia-331-uvm, if it makes a difference.
