I tried to find out what may be your problem with the hello message, but I cannot find anything wrong at a first glance.

To help with debugging this I ask you to try the attached patch and run 'LCDd -r 4 -f' (report level info, run in foreground) and send me the output of that.

It should contain something like this:

server_screen_init(), hello=4
line1 = [                    ]
line2 = [     Welcome        ]
line3 = [                    ]
line4 = [                    ]

Regards,
Markus
