.SH ARGUMENTS
.TP 12
.I display
Specifies the connection to the X server.
.TP 12

.SH DESCRIPTION
The
\fIXSetDeviceMode\fP
request changes the mode of an input device that is capable of reporting
either absolute positional information or relative motion information.  
Not all input devices are capable of reporting motion data, and not
all are capable of changing modes from \fIAbsolute\fP to \fIRelative\fP.
.LP
\fIXSetDeviceMode\fP
can generate a \fIBadDevice\fP or
\fIBadMode\fP 
error.
.SH DIAGNOSTICS
.TP 12
\fIBadDevice\fP
An invalid device was specified.  The specified device does not exist or has 
not been opened by this client via \fIXOpenInputDevice\fP.  This error may
also occur if some other client has caused the specified device to become
the X keyboard or X pointer device via the \fIXChangeKeyboardDevice\fP or
\fIXChangePointerDevice\fP requests.
.TP 12
\fIBadMatch\fP
This error may occur if an \fIXSetDeviceMode\fP request is made 
specifying a device that has no valuators and reports no axes of motion.
.TP 12
\fIBadMode\fP
An invalid mode was specified.  This error will also be returned if the
specified device is not capable of supporting the \fIXSetDeviceMode\fP
request.
