[lcd4linux] HD44780 20x2 only shows 8 characters

[Joao B. <bon...@ya...>]

Hello,

I'm trying a new lcd display, this time a CrystalFontz CFAH2002Y-PDI-ET (HD44780 compatible).

The problem is that it only shows 8 characters on line 1. If I send it more than 8 characters, nothing will show.

Also, can't get any widget to display on line 2.


the log and conf file are:
