Understanding the X Server Process
An X server is a single process that controls access to the hardware.
The X server performs the following functions:
Listens for incoming connections from new clients
Track inputs from input devices
Manages display access of the clients
Depending on the configuration of your Oracle Solaris system,
the X server is started from one of the following programs:
xdm, the X Display Manager
gdm, the GNOME Display Manager
The X client can connect to the X server by using TCP/IP, UNIX
domain sockets,
and several varieties of SVR4 local connections. For information
about specifying the transport type for clients, see the DISPLAY
NAMES section of the X(5) man page.
Working With X Servers
Oracle Solaris currently includes several X servers designed for
different usage types. The following
table lists some of the X servers included in the Oracle Solaris OS.
| |
|---|
Xorg
| Used with physical hardware (input and output) or in virtualization
environments that simulate physical hardware. For example,
an Xorg server is used when running an Oracle VM Virtual
Box guest or when using the keyboard, video, and mouse (KVM) functionality of the Oracle
ILOM service processors.
For detailed information, see the Xorg(1) man page.
|
Xvfb
| Used to allocate system virtual memory as a virtual frame buffer.
It does not receive input from any input devices and no output is
shown. Therefore, the system on which the Xvfb server
is running need not have a screen or any input device.
For detailed information, see the Xvfb(1) man page.
|
Xephyr
| Runs as a window displayed on another X server (host X server).
It uses the host X server's input and display devices.
For detailed information, see the Xephyr(1) man page.
|
Xvnc
| Runs a VNC session that can be connected by using a VNC client.
In a shared connection, multiple VNC clients can connect to the same
VNC session. The vncviewer is the default VNC client
that is available in the Oracle Solaris 11 OS.
For detailed information, see the vncserver(1) and vncviewer(1) man pages.
|
Xdmx
| Used as a proxy X server that uses one or more X servers for
displaying X clients. It provides X functionality for displays that
might be located on different machines.
For detailed information, see the Xdmx(1) man page.
|
Xnewt
| Interacts with Sun Ray clients such as Oracle Sun Ray 3 series DTU
hardware units or the Oracle Virtual Desktop client for Windows, MacOS, or iPad.

Solaris OS, see the Xserver(1) man page.
