FVWM is a powerful and highly configurable desktop window manager for the X Window system. It supports any number of virtual desktops, each divided into multiple pages. It also supports side title bars, including vertical text.
When you install FVWM on PC-BSD, it also installs FVWM-Crystal. Both window managers will be added to the login menu.
Figure 5.7a shows the default PC-BSD desktop if you select FVWM from the login menu.
