I am new to Linux. I have Ubuntu 14.04 with 3.16.0-33-generic kernel. I would like to use a second monitor and have a second desktop projected there (I have read this is know as Twinview).
I installed ARandR and the NVIDIA X Server Settings menu (of which I got only a simplified version) but they do not display an option to activate a second desktop in the other monitor. I just have two screens (my laptop's and the monitor) showing the same. Can anybody please help me to fix this?
