====== X2Go Sessions File Format Specification ======

Default path name

  * Linux, Mac OS X: ''$HOME/.x2goclient/sessions''
  * Windows (non-portable mode): session profiles are stored in the Windows registry (''HKEY_LOCAL_MACHINE\SOFTWARE\x2goclient'')
  * Windows (portable mode): session profiles are stored in a file (location???)

Related command line options:

  * x2goclient: --portable, --home, --session-conf
  * pyhoca-gui: --client-rootdir

==== Possible Session Command Combinations ====

  * Desktop sessions: (''command=[KDE,GNOME,LXDE,...]''):
    * KDE (startkde)
    * GNOME (gnome-session)
    * LXDE (lxde-session)
    * XFCE4 (xfce4-session, Python X2Go only)
    * TRINITY (starttrinity, Python X2Go only, don't miss the [[http://code.x2go.org/gitweb?p=python-x2go.git;a=blob;f=README.Trinity-Desktop|README.Trinity-Desktop]] file!!)
    * UNITY (unity-2d-launcher, Python X2Go only, very experimental and not well supported)

  * Single Applications (''command=[TERMINAL,WWWBROWSER,OFFICE,MAILCLIENT]''):
    * TERMINAL (find terminal application on server and launch)
    * WWWBROWSER (find browser on server ...)
    * OFFICE (find office application on server ...)
    * MAILCLIENT (find mail client on server ...)

  * Remote Desktop (''command=RDP''):
    * Setting the command to RDP will turn X2Go into an RDP proxy (RDP via NX). RDP will receive a performance improvement on WAN connections and X2Go will guarantee SSH encryption (whereas RDP drops encryption if the bandwidth won't suffice).
    * Make sure to use the options rdpserver and rdpoptions properly.

  * XDMCP (''command=XDMCP''):
    * Do an XDMCP query for the XDMCP server specified by the xdmcpserver option. Useful if you have a complex terminal server setup behind one X2Go gateway (e.g. handled by an XDMCP chooser).

  * Other applications (''command=<unix-application-on-server>''):
    * Specify any application (by its name) that is available via $PATH. No full path names are allowed here, the path will be stripped off of the file name provided. Make sure your $PATH environment variable resolves to the wanted application properly.

  * Published applications mode (''command=, published=true''):
    * Leave the command option empty and enable the option published
