(Change Version)

Fixed long standing bug with root user getting null output for res or tty, now if in X, shows message that gfx data is not available 
to root.

Also added null case handling for some of the gfx output to show N/A instead of null. This lets me know which detection fails, which 
should make debugging a bit easier long term.

Turned off the advanced glx info line as well for root user.
