I have some problems/ preference concerns
1. During installation, something weird occurred and for some reason I wasn't able to properly set a password for root(keyboard wasn't printing characters...), so at the moment, there is no password(I just hit enter). How can I change/ set it?
I also don't have any user logins(I read somewhere that root should only be used if necessary), and I don't know how to create new users.
2. When the desktop enviorment first loaded up(root/startx), I picked KDE, but would now like to try something else. How do I do that?
3. Also, I want to install Opera, and when I download the file all I get is source code(.js, .jar, etc). I find that pretty cool, but how do I actually install anything, heh.
