The X server runs as the given displaynumber, which
by default is 0. If multiple X servers are to run simultaneously on
a host, each must have a unique display number.
-a number
Sets pointer acceleration (that is, the ratio of how much is
reported to how much the user actually moved the pointer).
-ac
Disables host-based access control mechanisms. Enables access
by any host, and permits any host to modify the access control list.
Use with extreme caution. This option exists primarily for running
test suites remotely.
-audit level
Sets the audit trail level. The default level is 1, meaning
only connection rejections are reported. Level 2 additionally reports
all successful connections and disconnects. Level 0 turns off the audit trail. Audit lines are sent
as standard error output.
-auth authorization-file
Specifies a file which contains a collection of authorization
records used to authenticate access. See also the xdm and Xsecurity
manual pages.
bc
Disables certain kinds of error checking, for bug compatibility
with previous releases (such as working work around bugs in R2 and
R3 xterms and toolkits). Deprecated.
-bs
Disables backing store support on all screens.
-br
Sets the default root window to solid black instead of the standard
root weave pattern.
-c
Turns off key-click.
c volume
Sets key-click volume (allowable range: 0-100).
-cc class
Sets the visual class for the root window of color screens.
The class numbers are as specified in the X protocol.
-co filename
Sets name of RGB color database.
-core
Causes the server to generate a core dump on fatal errors.
-dpi resolution
Sets the resolution of the screen, in dots per inch. To be used
when the server cannot determine the screen size from the hardware.
-deferglyphs whichfonts
Specifies the types of fonts for which the server should attempt
to use deferred glyph loading. whichfonts can
be one of the following:
All (all fonts)
None (no fonts)
16 (16 bit fonts only)
-f volume
Sets feep (bell) volume (allowable range: 0-100).
-fc cursorFont
Sets the default cursor font.
-fn font
Sets the default font.
-fp fontPath
Sets the search path for fonts. This path is a comma separated
list of directories which the X server searches for font databases.
-help
Prints a usage message.
-I
Causes all remaining command line arguments to be ignored.
-nolisten trans-type
Disables a transport type. For example, TCP/IP connections can
be disabled with -nolisten tcp.
-noreset
Prevents a server reset when the last client connection is closed.
This overrides a previous -terminate command line option.
-p minutes
Sets screen-saver pattern cycle time in minutes.
-pn
Permits the server to continue running if it fails to establish
all of its well-known sockets (connection points for clients), but
establishes at least one.
-r
Turns off auto-repeat.
r
Turns on auto-repeat.
-s minutes
Sets screen-saver timeout time in minutes.
-su
Disables save under support on all screens.
-t number
Sets pointer acceleration threshold in pixels (that is, after
how many pixels pointer acceleration should take effect).
-terminate
Causes the server to terminate at server reset, instead of continuing
to run. This overrides a previous -noreset command line option.
-to seconds
Sets default connection timeout in seconds.
-tst
Disables all testing extensions (for example, XTEST, XTrap,
XTestExtension1, RECORD).
ttyxx
Ignored, for servers started the ancient way (from init).
v
Sets video-off screen-saver preference.
-v
Sets video-on screen-saver preference.
-wm
Forces the default backing-store of all windows to be WhenMapped.
This is a backdoor way of getting backing-store to apply to all windows.
Although all mapped windows will have backing store, the backing store
attribute value reported by the server for a window will be the last
value established by a client. If it has never been set by a client,
the server will report the default value, NotUseful. This behavior
is required by the X protocol, which allows the server to exceed the
client's backing store expectations but does not provide a way to
tell the client that it is doing so.
-x extension
Loads the specified extension at init. This is a no-op for most
implementations.
[+-]xinerama
Enables(+) or disables(-) the XINERAMA extension. The default
state is disabled.
