[lcd4linux] Problems using Crystalfontz 634 USB

[Michael M. <im...@im...>]

Hi everyone,

I've been trying to use my new Crystalfontz 634 USB with LCD4Linux and 
am experiencing an odd behavior.
On system boot the default logo of CF appears correctly. When the system 
has booted up, I'm manually loading the ftdi_sio module to get a ttyUSB0.
When I start up LCD4Linux now, I only see 4 dark bars when viewed from 
the front (everything seems to be set to black).
But when I move my head a far to one side of the display (about 30 
degree to the display) I can see the correct info being written on the LCD.

Does anyone have an idea why this is happening?
Here are the relevant parts of my configuration:

Display CF634 {
    Driver 'Crystalfontz'
    Model '634'
    Port '/dev/tts/USB0'
    Speed 19200
    Contrast 95
    Backlight 100
    Icons 0
}

Layout myDefault {
    Row1 {
        Col2 'CPU'
    }
}

Display 'CF634'
Layout 'myDefault'

I'd appreciate any help or hints.

best regards,
Michael
