Hello -
The problem may be that you have multiple settings specified.  Try
commenting out all but the server you actually want to use. (see below)

This has been addressed before on this list, and I can't remember
exactly how it's solved - something to do with adding an option to use
raw input.  Search the archives for this one.

All this looks fine.

This should be commented out - leave only one screen section.

Try this first - if it doesn't work for you - write back.  There are
ways to specify how the X server lines itself up on the screen - offsets
and so forth.  But his looked like an easier staring point.
Good luck,
