Super user privileges required on Linux

```
Super user/root user privileges required to run the software on GNU/Linux.
This is because of a kernel level key logger (Linux User Input Device Event
Interface).

Possible Fixes: 
1. setuid.
2. Develop a new key logger which functions at user level. Xlib is one such
possibility.
