All right, always willing to help the rueful sinner ;-)

One hint in general: it pays off to see what your commands *would* do
before really doing something recursive. If you have zsh, you could have
hit tab right after typing the asterisk 'chmod -R 755 *<TAB>' and all
the possible file names would have been completed on the command line.
You had seen your error fast here. If you want to act on directories,
use '*(/)' instead of '*' (zsh only again). Or use a for loop:
# for i in `find . -type d`; do echo chmod 755 $i; done
If you like what you see, remove the 'echo' and go on. This
doesn't cost you much but can help immensely.

First of all your main problem is that /usr/X11R6 does not just contain
the X server but many applications too, so no simple recursive approach
will work. Basically it is no problem that some executables are root-only
since the X server runs as root (chmod 4755 /usr/X11R6/bin/Xwrapper).
Without ever having installed an X server on my own I suggest
trying these, first to last (assuming that you are running a Linux box):
1) See if your distribution can set the permissions for you. This may
not be obvious and you may have to read some documentation on this
topic (I can do it with my SuSE distribution).
2) Try to get the latest XFree86 package from your distributor. This
should have the correct permissions set and can usually be
downloaded for free.
3) Read the installation instructions carefully. There must be some
hint how to properly install the X server so that everybody can
use it.

Well, I never understood how these screen sections have to look,
but perhaps this excerpt from my XF86config helps you:

I don't think the order matters but make sure that you are really
running the X server spcified in the 'Device' line. Try the
manpage for XF86Config. It describes the file format.
