What is the difference between Xmanager's default server and classic server?
There are two types of X servers in Xmanager 7.
In most user environments, both will operate fine and you don’t need to explicitly choose one over the other. But in the following cases, we recommend you choose the appropriate X server for optimal performance.
Choose the default X server if you are:
Connecting to Solaris 11.4
Connecting to Redhat Enterprise Linux, CentOS 7.x or higher
Connecting to Ubuntu 13.04 version or higher
Accessing other relatively modern Linux machines
Choose the classic X server if you are:
Accessing traditional UNIX such as Solaris, HP-UX, and AIX
Connecting to Redhat Enterprise Linux, CentOS 6.X or lower
Accessing Ubuntu 12.10 or lower version
Accessing other relatively older Linux machines
