Case Sensitive Sorting in Ubuntu

[Adam Done]

Ever since I have switched to Ubuntu and have been enjoying the
experience but the one thing that has been troubling me is the lack of
case sensitivity which I really love and use a lot on the systems.

I know it is not just ls.. for I had looked into that and notice it is
from everything in the terminal to all GUI.   Is there a setting I am
missing since I am so perplexed?

Thanks
