Each Xmanager session logs debugging information as a file in a user folder. When multiple Xmanager sessions are running at the same time, each session generates log messages in a different file such as X0.LOG, X1.LOG, and so on. The number on the log file indicates the display number of an Xmanager session.
When you experience a problem in using Xmanager, it is helpful to see the log file.
