Want to make the VFD work on your Media Live?
It's quite simple.
Install this version of LCDproc:
LCDproc that is included in Ubuntu or a newer version do not contain the DM-140 driver that you need.
After installation, nano /etc/init.d/LCDd
Change the DEAMON_OPTS line to: DAEMON_OPTS="-s true -f -c /etc/LCDd.conf -d dm140 -r 5"
If everything is working your VFD should start working and shows the server part.
To make it show something usefull, simply exacute the command: lcdproc
Now it should display time/load/lan etc information, you can edit that by edtting the lcdproc.conf
This worked for me, oh and best stop apt from trying to update lcdproc else it will stop working.
