+.B \-xinerama
+Enable Xinerama support - disabled by default. Xinerama is an X server extension
+that allows multiple physical screens to behave as a single screen. With traditional
+multi-head in X11, windows cannot span or cross physical screens.
+
+Please notice that some window managers are not Xinerama-aware, and so some operations
+like window placement and resizing might not behave in an ideal way. This is an issue
+that needs to be dealt with in the individual window managers and not within grml-x
+or X server.
