I appreciate there are a lot of similar questions to this already but I can't seem to fix it following any current threads.
I have installed 64bit Ubuntu 13.04 and installed the Nvidia drivers as per this thread: http://www.dedoimedo.com/computers/ubuntu-quetzal-nvidia.html
The drivers seem to be working correctly and I can access the nvidia-settings, but detect displays does not detect my second monitor (actually an LG TV if it matters connected through HDMI) from either nvidia-settings or the standard display option.
Some of the other threads mention editing the etc/X11/xorg.conf file but it doesn't exist on my system, at that location at least.
Any help would be appreciated, and thanks in advance.
