Those last four words are the important part! =:^) As long as it helps
some and isn't actively messing others up, it's all good! =:^)

The xorg.conf manpage covers a lot of this.
You have the Option "DPMS" set in two different sections, the monitor
section (identified as "Monitor0" and the screen section (identified as
"Screen0". Neither of those are global to the X-session as a whole, as
there can be more than one X "screen", each of which can contain more than
one "monitor".
As an aside, the way you posted the text on the forums works as X doesn't
care about indention (it's X readable), but it's not particularly human
readable. The more traditional way to write it would indent the contents
of each section, emphasizing the section hierarchy, like so (following
your lead I've truncated a few more lines for posting, indicating them
with dots ".....":

Again, the xorg.conf manpage (which I do truly hope your distro installs,
it's /ever/ so helpful!) has several short example sections demonstrating
this. As I said, it's whitespace agnostic. As long as you have at LEAST
one space between entries on a line and don't split or combine lines, X
won't care. So while I used tabs above, you can use spaces, like so...
Section "Example"
Identifier "Example0"
Entry "Value0"
SubSection "Subsect"
Subentry "x" "y" "z"
EndSubSection
Option "OptA" "FALSE"
EndSection
... You can line up the values too if desired....
Section "Example"
Identifier "Example0"
Entry "Value0"
SubSection "Subsect"
Subentry "aaaa" "bbbb" "xxxx"
EndSubSection
Option "OptA" "FALSE"
EndSection
Be sure to keep quoted values quoted and bare values bare, however. That
DOES matter!
The above makes it far clearer what's going on, and that you indeed do
have DPMS options in two different sections. The xorg.conf manpage puts
the DPMS option in the monitor section, thus allowing you to set monitors
differently if you have more than one. It appears that you only have one
monitor, however, and I suspect that it's actually this section's DPMS
option that's being used. You can thus likely delete the screen section
DPMS option and still have it work. The caveat is that you're running the
nVidia proprietary driver, which may have its own rules. I believe it
comes with its own rather detailed README file documenting its config.
You can either read that and figure it out, or simply try it with only the
monitor section DPMS option, and see.
Meanwhile... the files section is entirely empty so you might as well
remove that. Obviously the xorg defaults are sufficient for your system.
It's also quite likely that those InputDevice sections are being ignored
by a modern xorg-server. Even if they're not being ignored as-is, you
don't have anything particularly special in them, so it's likely you don't
need them. Backup your existing file somewhere, delete them, and restart
X. If it works fine, you just simplified your config dramatically! =:^)
(If it doesn't, however, you'll not have keyboard and/or mouse and may
have to Ctrl-Alt-F1 to get to a text console and copy the working file
back, or even possibly reset in ordered to get out of the test, then
choose to boot into safe or no-X mode in ordered to copy the working file
back. But I'm betting it'll work fine.)
Likewise, on a modern xorg-server, you can probably do without that
ServerLayout section, since it's pretty much the default and xorg will use
its built-in default without it.
The screen section *MAY* also be removable. It doesn't appear that you
have anything really out of the ordinary there. It's optional on current
xorg and current drivers. However, the nVidia proprietary driver tends to
lag a bit in current xorg-server compatibility, and may still require it
especially if the driver isn't randr-1.2 compliant, yet. Again, try it
and see.
The really important bits for you are the device section, where you
specify the driver to use and its options, and the monitor section. Both
of these are likely necessary in your case, since you're specifying the
nVidia closed driver and some custom options for it, and you need the dpms
option in the monitor section. It's also possible that those no-edid
options you're using in the device section require the screen section with
its mode information. You'd need to either consult your nvidia
documentation or simply try it without, to see.
