XQUARTZ(1)XQUARTZ(1)NAMEXquartz - X window system server for Mac OSX
SYNOPSISXquartz [ options ] ...
DESCRIPTIONXquartz is the X window server for Mac OS X provided by Apple. Xquartz
runs in parallel with Aqua in rootless mode. In rootless mode, the X
window system and Mac OS X share your display. The root window of the
X11 display is the size of the screen and contains all the other win‐
dows. The X11 root window is not displayed in rootless mode as Mac OS X
handles the desktop background.
CUSTOMIZATIONXquartz can be customized using the defaults(1) command. The available
options are:
defaults write org.macosforge.xquartz.X11 enable_fake_buttons -boolean
true
Emulates a 3 button mouse using modifier keys. By default, the
Command modifier is used to emulate button 2 and Option is used
for button 3. Thus, clicking the first mouse button while hold‐
ing down Command will act like clicking button 2. Holding down
Option will simulate button 3.
defaults write org.macosforge.xquartz.X11 fake_button2 modifiers
Change the modifier keys used to emulate the second mouse but‐
ton. By default, Command is used to emulate the second button.
Any combination of the following modifier names may be used:
{l,r,}shift, {l,r,}option, {l,r,}control, {l,r,}command, fn
defaults write org.macosforge.xquartz.X11 fake_button3 modifiers
Change the modifier keys used to emulate the second mouse but‐
ton. By default, Command is used to emulate the second button.
Any combination of the following modifier names may be used:
{l,r,}shift, {l,r,}option, {l,r,}control, {l,r,}command, fn
defaults write org.macosforge.xquartz.X11 fullscreen_hotkeys -boolean
true
Enable OSX hotkeys while in fullscreen
defaults write org.macosforge.xquartz.X11 fullscreen_menu -boolean true
Show the OSX menu while in fullscreen
defaults write org.macosforge.xquartz.X11 no_quit_alert -boolean true
Disables the alert dialog displayed when attempting to quit
X11.
defaults write org.macosforge.xquartz.X11 no_auth -boolean true
Stops the X server requiring that clients authenticate them‐
selves when connecting. See Xsecurity(7).
defaults write org.macosforge.xquartz.X11 nolisten_tcp -boolean false
This will tell the server to listen and accept TCP connections.
Doing this without enabling xauth is a possible security con‐
cern. See Xsecurity(7).
defaults write org.macosforge.xquartz.X11 enable_system_beep -boolean
false
Don't use the standard system beep effect for X11 alerts.
defaults write org.macosforge.xquartz.X11 enable_key_equivalents -bool‐
ean false
Disable menu keyboard equivalents while X11 windows are
focused.
defaults write org.macosforge.xquartz.X11 depth depth
Specifies the color bit depth to use. Currently only 15, and 24
color bits per pixel are supported. If not specified, or a
value of -1 is specified, defaults to the depth of the main
display.
defaults write org.macosforge.xquartz.X11 sync_keymap -boolean true
Keep the X11 keymap up to date with the OSX system keymap.
defaults write org.macosforge.xquartz.X11 option_sends_alt -boolean
true
The Option key will send Alt_L and Alt_R instead of
Mode_switch.
defaults write org.macosforge.xquartz.X11 sync_pasteboard -boolean true
Enable syncing between the OSX pasteboard and clipboard/primary
selection buffers in X11. This option needs to be true for any
of the other pasteboard sync options to have an effect.
defaults write org.macosforge.xquartz.X11 sync_pasteboard_to_clipboard
-boolean true
Update the X11 CLIPBOARD when the OSX NSPasteboard is updated.
defaults write org.macosforge.xquartz.X11 sync_pasteboard_to_primary
-boolean true
Update the the X11 PRIMARY buffer when the OSX NSPasteboard is
updated.
defaults write org.macosforge.xquartz.X11 sync_clipboard_to_pasteboard
-boolean true
Update the the OSX NSPasteboard when the X11 CLIPBOARD is
updated. Note that enabling this option causes the clipboard
synchronization to act as a clipboard manager in X11. This
makes it impossible to use xclipboard, klipper, or any other
such clipboard managers. If you want to use any of these pro‐
grams, you must disable this option.
defaults write org.macosforge.xquartz.X11 sync_primary_on_select -bool‐
ean true
This option defaults to false and is provided only "for
experts." It updates the NSPasteboard whenever a new X11
selection is made (rather than requiring you to hit cmd-c to
copy the selection to the NSPasteboard). Since the X11 proto‐
col does not require applications to send notification when
they change selection, this might not work in all cases (if you
run into this problem, try selecting text in another applica‐
tion first, then selecting the text you want).
defaults write org.macosforge.xquartz.X11 enable_test_extensions -bool‐
ean true
This option defaults to false and is only accessible through
the command line. Enable this option to turn on the DEC-XTRAP,
RECORD, and XTEST extensions in the server.
defaults write __laucnd_id_prefix__.X11 scroll_in_device_direction
-boolean true
This option defaults to false. Enable this option to ensure
that X11 scroll events are always in the direction of the
device. This overrides the related option in the Mouse/Track‐
pad section of System Preferences.
OPTIONS
In addition to the normal server options described in the Xserver(1)
manual page, Xquartz accepts the following command line switches:
-fakebuttons
Same as enable_fake_buttons above with value true.
-nofakebuttons
Same as enable_fake_buttons above with value false.
-fakemouse2 modifiers
Same as fake_button2 above.
-fakemouse3 modifiers
Same as fake_button3 above.
-depth depth
Same as depth above.
LOGGING
XQuartz stores a server log at ~/Library/Logs/X11.org.macos‐
forge.xquartz.log which is analogous to /var/log/Xorg.#.log on systems
that use the XFree86 DDX such as Linux, BSD, and Solaris.
In addition to this server log, XQuartz sends messages to syslogd(8)
using asl(3). These logs are sent to the org.macosforge.xquartz facil‐
ity, and you can watch these logs using the following syslog(1) com‐
mand:
$ syslog -w -k Facility eq org.macosforge.xquartz
or you can include extra information such as the file, line, and func‐
tion where the message originated:
$ syslog -w -F '$(Time) $(Sender) <$(Level)> $(File):$(Line) $(Func‐
tion) :: $(Message)' -k Facility eq org.macosforge.xquartz
By default, XQaurtz sets an ASL mask which prevents it from logging
messages below the ASL_LEVEL_WARNING level (meaning almost all logging
is done strictly to the file referenced above). To force XQuartz to
send all log messages to syslogd(8), you can adjust this mask using the
following syslog(1) command:
$ syslog -c X11.bin -d
The stdout and stderr messages printed by any process launched by
XQuartz will be redirected to this syslog facility with a priority
level of ASL_LEVEL_INFO and ASL_LEVEL_NOTICE respectively. In order to
see these messages in syslog, you will need to adjust XQuartz's asl
mask as above but using -i or -n instead of -d.

AUTHORS / HISTORY
X11 was originally ported to Mac OS X Server by John Carmack. Dave
Zarzycki used this as the basis of his port of XFree86 4.0 to Darwin
1.0. Torrey T. Lyons improved and integrated this code into the
XFree86 Project's mainline for the 4.0.2 release.
The following members of the XonX Team contributed to the following
releases (in alphabetical order):
XFree86 4.1.0:
Rob Braun - Darwin x86 support
Torrey T. Lyons - Project Lead
Andreas Monitzer - Cocoa version of XDarwin front end
Gregory Robert Parker - Original Quartz implementation
Christoph Pfisterer - Dynamic shared X libraries
Toshimitsu Tanaka - Japanese localization
XFree86 4.2.0:
Rob Braun - Darwin x86 support
Pablo Di Noto - Spanish localization
Paul Edens - Dutch localization
Kyunghwan Kim - Korean localization
Mario Klebsch - Non-US keyboard support
Torrey T. Lyons - Project Lead
Andreas Monitzer - German localization
Patrik Montgomery - Swedish localization
Greg Parker - Rootless support
Toshimitsu Tanaka - Japanese localization
Olivier Verdier - French localization
Code from Apple's X11.app (which was based on XFree86 4.1) was inte‐
grated into X.org's XDarwin DDX by Ben Byer for xorg-server-1.2. The
XDarwin DDX was renamed Xquartz to more accurately reflect its state
(the pure-darwin backend was removed). Jeremy Huddleston took over as
project lead and brought the project up to the X.org 1.4 server branch.
Jeremy Huddleston <jeremyhu@apple.com> is the current maintainer.
