Xmanager supports command line options to interface with other user applications. When you run Xmanager directly, it does not read an Xstart or Xbrowser session and you should specify the connection method and display number as command line options.

Xmanager command line usage:

Xmanager [-query hostname|-broadcast|-indirect hostname] [:digit]

Some examples are listed below.

Xmanager Runs as a passive mode with the default Xstart profile. The display number is 0 by default; if it is not available, another number is allocated automatically.
