[lcd4linux] Configuration question

[Leif L. <le...@sm...>]

Hi everyone,

Anyway, I'm having problems figuring out how to configure lcd4linux to
enable/disable backlight on keypad presses.

Non-successful configuration file appended to this email.

Using CVS version built about an hour ago.

Could someone give me a hint as to where I'm messing up?

best regards
