Hello Santau,

first of all: Can you tell us how the Mplay VFD is connected to your
computer? What type of cable is it? Does this device appear in your
computers config? If it is connected by USB you should see some USB
device in your system config.

Related to your second message: running LCDd with '-r 5' will produce a
lot of debug output. In your case LCDd did start up and you saw the
debug output for the default server screen.

The FTDI connection type requires the use of libusb and libftdi. Lcdproc
must be compiled with these installed to be able to make use of them. As
I don't know how the Ubuntu package makers configured lcdproc, I suggest
you compile lcdproc from source yourself.
