 How did you get /usr/X11/share/X11 ?  I suppose you have built xorg in
/usr/X11 instead of /usr.  Seems an unusual thing to do.

 I can see that the book symlinks /etc/X11 [ unnecessary for those
of us who build xorg in /usr, but perhaps useful if you are
intending to install newer versions of xorg on the same base system
- for myself, /usr (and good backups, with logs of what gets
installed) is far simpler.

 Well, my own 10-evdev.conf has
Section "InputClass"
on line 7 and appears to work.

 I also have 11-keyboard.conf (the name isn't important) with a
similar line.

 So, you are using what I regard as an odd --prefix (other people
here will think it is perfectly sane, and it certainly ought to work
if used *throughout_xorg*).  Did you use this prefix for *all* the
xorg packages ?

 Have you omitted any xorg packages ?  I omit *loads*, but I'm
thinking that you maybe missed something which handles how the conf
files are parsed.  I've certainly not seen any reports of this sort
of error, and for the moment it baffles me.

I did build Xorg in /usr/X11. That shouldn't be a problem, right? I'm not sure what went wrong, but I found a
workaround: I moved all the options in /etc/X11/xorg.conf.d/* to /etc/X11/xorg.conf, leaving
/etc/X11/xorg.conf.d empty. Now X works, don't ask me why, though...

Thanks for the help!

 Glad you got it working.  In *theory*, /usr/X11 (or, indeed, any
other prefix) *shouldn't* be a problem (if PKG_CONFIG_PATH, PATH and
/etc/ld.so.conf know about it - but problems from that would
normally be *build* problems).  Some time ago (between 2 and 4
years ago, I think) I tried building xorg in /somewhere/xorg-v.w.x
and similarly gnome in /somewhere/gnome-2.ab.c (I forget if I was
using /opt or /usr for the 'somewhere').  The theory was that I
would be able to update xorg, and similarly the part of gnome that I
was using, without rebuilding the system.

 In the event, I abandonned that - too many build problems.  Now I
build my normal things in /usr (occasionally, I make an exception for
disreputable packages that I need to use for something in the book -
they go in /opt and are only referenced when needed [ so, nothing
that installs a library - I don't try to modify ld.so.conf ].

 The bigger problem with using other prefixes so that newer versions
can be built without trashing the current version is that libraries
*do* change - if I've linked all my desktop packages against a
year-old version of xorg, updating *might* cause obscure breakage.

I followed the instructions for building in /opt just last December and 
it works fine.  Yes, I did add one line to /etc/ld.so.conf, and 
PATH/PKG_CONFIG_PATH are updated too.  I used:

XORG_CONFIG='--prefix=/opt/xorg --sysconfdir=/etc \
              --mandir=/opt/xorg/share/man --localstatedir=/var'
XORG_PREFIX=/opt/xorg

I've not seen any problems at all.

Well done for getting it working. Sorry I didn't offer any helpful
suggestions but I had no clue what the problem was. However, the way
you fixed it suggests that there was a problem with
the /usr/X11/share/X11/xorg.conf.d/10-evdev.conf file. Perhaps it was
some unprintable character that doesn't show up in a text editor? Or
maybe something to do with locale or language settings?
Thanks for posting how you fixed the problem.
