let me guess... you are running as root?
.X*
and
.ICE*
are both for your x server...
All '.' (dot) files don't show up on a standard 'ls' or in your file browser by default. They are hidden, and often used for config files. . . over time you will build up quite a lot of them with the different programs you use.
I would suggest you create a user account to use... if you have not already.
Also... please read this:
