[Lcdproc] CFontz 634 (serial) only gets blank screen

[Cameron Dale]

I just started using lcdproc for my CrystalFontz 634 serial LCD and
I'm having some trouble getting it to work with LCDproc. I've
confirmed that it works with the "test_632_634" program from
CrystalFontz (it displays the 4 numbered lines properly).

When I start LCDd with the command "LCDd -f -c /etc/LCDd.conf", the
display shows the CrystalFontz screen when I set Reboot to yes, but
after that I get a flashing prompt in the top left corner that
disappears after 2 seconds. The server/clients screen never appears
like it does when I use the curses driver. Maybe the problem is that I
don't have any power to the backlight, but I thought it should still
work (dimly) without it.

Here are my specs:

CrystalFontz 634 V2.2 (serial)
Debian Unstable
Linux 2.6.18 (AMD64)
lcdproc 0.5.1-3 (Debian package)

And here is my config file:
