The "About" icon of Control Panel can be used to quickly find information about the PC-BSD system. To start the application, double-click its icon in Control Panel or type about-gui. An example is seen in Figure 8.2a.
This screen displays the version of PC-BSD, the architecture, where i386 equals 32-bit and amd64 equals 64-bit, and the hostname of the system. The "FreeBSD base" section displays the version and architecture of the underlying FreeBSD system and the name of the kernel (ident). The "Hardware" section indicates the type of CPU and the amount of installed memory.
If you click the "System components" button, the X.org version and the revision number of the command line and graphical utilities are displayed, as seen in the example shown in Figure 8.2b.
If you click the "Desktop environments" button, the currently installed desktops will be displayed, as seen in the example shown in Figure 8.2c. If you wish to install additional desktops, use the System Packages tab of System Manager.
