ehhhh.... I think you've got a few things mixed up.

LessTif == clone implementation of the Motif widget mess. Used to make
X11 application interfaces.

FVWM2 == very olde fashionede X11 windowmanager. Used to add decorations
like titlebars and minimize/maximise buttons to X11 applications. As a
bonus FVWM2 adds a program starter thing too.

Important point: A X11 windowmanager isn;t necessarily tied to the
toolkit your application is using. If windowmanager W uses say the Gtk
toolkit and the X11 application A uses the Motif toolkit, the two will
work fine if:

1. the 2 toolkits are available on your system
2. the windowmanager and application honour the ICCCM conventions for
windowmanager <-> application communication.

Thus: DDD will run without any problems at all using the FVMW2
windowmanager, but you'll need LessTif installed someplace sensible on
your system for DDD's UI to work. Have a look on the DDD website, and
you;ll see that the screenshots show DDD running with the KDE
windowmanager, which is based on the Qt toolkit.

hope this helps a little,

PS. As to rebooting, unix boxen generally don;t need reboots for any
system administration tasks, the main exception being kernel upgrades.
