If the suid wrapper is enabled, /usr/bin/Xorg is just a shell script that
execs either /usr/libexec/Xorg.bin directly or the Xorg.wrap binary which then
execve's /usr/libexec/Xorg.bin.
Either way, we end up with Xorg.bin, which is problematic for two reasons:
* ps shows the command as Xorg.bin
* _COMM and _EXE in systemd's journal will both show Xorg.bin as well
There's not much we can do about the path, but having the actual command stay
as Xorg means better compatibility to existing scripts. And, the reason for
this path: the command
journalctl _COMM=Xorg
works universally, regardless of whether the wrapper is used or not.

The OutputClass section provides a way to match output devices to a set
of given attributes and configure them. For now, only matching by kernel
driver name is supported. This can be used to determine what DDX module
to load for non-PCI output devices. DDX modules can ship an xorg.conf.d
snippet (e.g. in /usr/share/X11/xorg.conf.d) that looks like this:
Section "OutputClass"
Identifer "NVIDIA Tegra open-source driver"
MatchDriver "tegra"
Driver "opentegra"
EndSection
This will cause any device that's driven by the kernel driver named
"tegra" to use the "opentegra" DDX module.
See the OUTPUTCLASS section in xorg.conf(5) for more details.

With the recent systemd-logind changes it is possible to install the Xorg
binary without suid root rights and still have everything working as it
should *if* the user only has cards which are supported by kms.
This commit adds a little suid root wrapper, which is a bit weird, first we
strip the suid-root bit of the Xorg binary, and then we add a wrapper ?
The function of this wrapper is to see if a system still needs root-rights,
if it does not (it supports kms and the kms drivers are properly loaded),
then it will immediately drop all elevated rights before executing the real
Xorg binary. If it finds (some) cards which don't support kms, or no cards
at all, then it will execute the Xorg server with elevated rights so that
ie the nvidia binary driver and the vesa driver can keep working normally.
To make it possible for security concious users who don't need the root
rights to completely remove the wrapper, Xorg is started in a 3 step process
when the wrapper is enabled during build time:
1) A simple shell script which checks if the wrapper is there, if it is
it executes the wrapper, if not it directly executes the real Xorg binary
2) The wrapper gets executed, does its checks, normally drops all elevated
rights and then executes the real Xorg binary
3) The real Xorg binary does its thing
This allows distributions to put the wrapper binary in a separate package, and
will allow users to remove this package. IE the plan with Fedora is to make
"legacy" drivers depend on the wrapper pkg, and since our default install
contains some legacy drivers it will be part of the default install, but
users can later yum remove it (which will also automatically remove the
legacy driver packages as those won't work without it anyways).
The wrapper is loosely modelled after the existing Debian Xwrapper, it
uses the same config-file + config-file format, and also allows restricting
Xserver execution (through the wrapper) to console users only.
There also is a new needs_root_rights config file directive, which can
be used to override the auto-detection the wrapper does.
Hopefully this will allow Debian to replace their own wrapper with this
upstream one.

The option's effect is to search for and mark once each named mode in
the output modes list. So the specification order is free and the zoom
modes sequence follows the order of the output modes list. All marked
modes are available via the Ctrl+Alt+Keypad-{Plus,Minus} key
combination.

This option has its use for combined monitor and television setups.
It allows for easy switching between 60 Hz and 50 Hz modes even when a

This will fix inconsistencies and prevent the creation of new unneeded

The xorg.conf manual uses the following convention in most of its
sections:
bold = text to be copied literally to the config file,
italic = a symbolic name to be substituted by a true value.
Some configuration keywords seem to have been changed into generic
options. Prepending Option to the manual entry swapped the
bold-italic logic. This patch restores the convention in the monitor
section and consists of
-.BI "Option " "\*qPreferredMode\*q " \*qstring\*q
+.BI "Option \*qPreferredMode\*q \*q" name \*q
modifications.
Plus a few minor changes (Modes → Mode) and a typo fix.
