Low level X11 programming
How to use X11 without Xlib not XCB? How draw window directly on low level?
I must use anyway window manager like Motif?
I have ridden that X11 has server-client architecture, client send via TCP/IP to port 6000 request for primitives and get replies.
Where is detailed description of it? In X11 doc is 35 directories like bigreqsproto, compositeproto, damageproto, dri2proto ...

I see that usually not using port 6000 but file (symlink) X0 in hidden directory /tmp/.X11-unix
----
I begin to understand thanks to x11protocol.pdf from doc.tar.bz2 from ftp://ftp.ntua.gr/pub/X11/X.org/X11R7.7, but I don't know if is possible copy bitmap from client to server? Is request CopyArea but this copy area from on place of screen to other. Requests are small and sending big bitmaps is time consuming especially with remote servers. In other hand - memory bitmaps enable fast pixel changing, for example I read jpg from file to memory. If I have image in memory, how send it to server?

pax11publish(1) 					      General Commands Manual						   pax11publish(1)

NAME

       pax11publish - PulseAudio X11 Credential Utility

SYNOPSIS

       pax11publish -h

       pax11publish [options] [-d]

       pax11publish [options] -e

       pax11publish [options] -i

       pax11publish [options] -r

DESCRIPTION

       The  pax11publish  utility  can be used to dump or manipulate the PulseAudio server credentials that can be stored as properties on the X11
       root window.

       Please note that the loadable module module-x11-publish exports the same information directly from the PulseAudio sound server, and  should
       in most cases be used in preference over this tool.

       Use the following command to dump the raw PulseAudio-specific data that is stored in your X11 root window:

       xprop -root | grep ^PULSE_

OPTIONS

       -h     Show help.

       -d     Read  the  PulseAudio server credentials currently set on the X11 root window and dump them in a human readable form. This reads the
	      PULSE_SERVER, PULSE_SINK, PULSE_SOURCE and PULSE_COOKIE properties.

       -i     Similar to -d, however dumps them in a Bourne shell compatible format so they may be used together with the eval	shell  command	to
	      set  the	$PULSE_SERVER, $PULSE_SINK, $PULSE_SOURCE environment variables. Also reads the authentication cookie from the root window
	      and stores it in ~/.config/pulse/cookie.

       -e     Export the currently locally used sound server, sink, source configuration to the X11 root window. This  takes  the  data  from  the
	      $PULSE_SERVER, $PULSE_SINK, $PULSE_SOURCE environment variables and combines them with the data from ~/.config/pulse/client.conf (or
	      /etc/pulse/client.conf if that file does not exist). If specific options are passed on the command line (-S, -O, -I, -c, see below),
	      they take precedence. Also uploads the local authentication cookie ~/.config/pulse/cookie to the X11 server.

       -r     Removes the configured PulseAudio configuration from the X11 root window.

       -D DISPLAY
	      Connect to the specified X11 display, instead of the default one configured in $DISPLAY.

       -S SERVER
	      Only valid for -e: export the specified PulseAudio server as default to the X11 display instead of the one configured via local con-
	      figuration.

       -O SINK
	      Only valid for -e: export the specified sink as default sink to the X11 display instead of the one configured via  local	configura-
	      tion.

       -I SOURCE
	      Only valid for -e: export the specified source as default to the X11 display instead of the one configured via local configuration.

       -c FILE
	      Only  valid  for	-e: export the PulseAudio authentication cookie stored in the specified file to the X11 display instead of the one
	      stored in ~/.config/pulse/cookie.
