Hello.
I get the nmedia PRO-LCD unit (http://www.nmediapc.com/prolcd.htm) installed on linux with lcdproc.
My lis driver section on the LCDd.conf file is set to default values (Size=20x2).
But the last character on the first line is never displayed by lcdproc.
At startup, i can see the vendor logo moving over this part, so it isn't seem to be an hardware issue, that's why i think it's a LCDd/lcdproc issue.
(context : lcdproc 0.5.7-2 archlinux on x86_64)
Have a nice day.
