X Server partial list of the files, terms, and utilities used

Managing the Graphical Environment


The following is a partial list of  the files, terms, and utilities used:



• /etc/X11/xorg.conf

  X Configuration File. If you’re using X.org on a Linux distribution
  that uses the init daemon, your configuration settings are saved in
  /etc/X11/xorg.conf. If you’re using XFree86, your configuration
  settings are saved in /etc/X11/XF86Config.



• xhost

  You can also tunnel your X server traffic to remote X clients using an
  SSH connection. To do this, you must configure the client system to
  accept connections from the X server using the

  xhost +X_server_hostname 

  command.


• DISPLAY

  Then you configure the X server to redirect its graphical display to
  the client system by setting the DISPLAY environment variable. The
  syntax is

  DISPLAY=X_ client_hostname:0.0.


• xwininfo

  The xwininfo command can be used to display information about open
  windows on your graphical desktop. You can run the command and then
  click the window you want to get information about.


• xdpyinfo

  The xdpyinfo command can be used to display the capabilities of a
  server, the various parameters used when communicating between clients
  and the server, and the different screen modes available.


• X

  If you’re in runlevel 3 and want to start the Linux GUI, simply enter
  startx (which is a simple shell script wrapper for xinit) or just X at
  the shell prompt.
