[kde-doc-english] Password

[Tom Staley]

This is my first time with Kubuntu 14.10, I understand Windows pretty 
well but am lost here.
When opening an application it prompts for a password, so I enter my 
password and nothing happens. What can I do to fix this. I am trying to 
make Windows 7 my first boot and downloaded grub-optimizer and it 
prompts for a password.

I also cannot logout of facebook in Kubuntu 14.19
