I installed Unity3d on Ubuntu 14.04 LTS. It works, and I want to get started. So I make a C# script, and when I try to open it nothing happens. No error message, no anything. I just double click it or right click and select "open", and nothing happens. So I went to preferences, and I selected the gnome text editor, and when I double click it now, it opens up the script. So it is clearly a problem with MonoDevelop. When I try to open up MonoDevelop without using unity3d, just the application, nothing happens a well. Does anyone know what the problem is, and how to solve it?
