+.RI [ :display ]
+.RI [ option ...]
+
+.B Xfbdev
+.RI [ :display ]
+.RI [ option ...]
+.SH DESCRIPTION
+.B Xkdrive
+is a family of X servers designed to be particularly small. This
+manual page describes the common functionality of the
+.B Xkdrive
+servers; for information on a specific X server, please refer to the
+relevant manual page.
+.SH OPTIONS
+In addition to the standard options accepted by all X servers (see
+Xserver(1)), all the
+.B Xkdrive
+servers accept the following options:
+.TP 8
+.B -card \fIpcmcia\fP
+use pcmcia card as additional screen.
+.TP 8
+.B -dumb
+disable hardware acceleration.
+.TP 8
+.B -origin \fIX\fP,\fIY\fP
+Locates the next screen in the Xinerama virtual screen.
+.TP 8
+.B -screen \fIwidth\fBx\fIheight\fR[\fBx\fIdepth\fR[\fBx\fIfreq\fR]]\fR[\fB@\fIrotation\fR]\fB
+use a screen of the specified \fIwidth\fP, \fIheight\fP, screen \fIdepth\fP, \fIfrequency\fP, and \fIrotation\fP (0, 90, 180 and 270 are legal values).
+.TP 8
+.B -softCursor
+disable the hardware cursor.
+.TP 8
+.B -videoTest
+start the server, pause momentarily, and exit.
+.TP 8
+.B -zaphod
+disable switching screens by moving the pointer across a screen boundary.
+.TP 8
+.B -2button
+enable emulation of a middle mouse button by chording.
+.TP 8
+.B -3button
+disable emulation of a middle mouse button by chording.
