DIAGNOSTICS

lcd4linux on foreground writes (depending on level) to stdout or stderr. The Text-Driver has its own diagnostics window. Started in the background (the default), lcd4linux uses your syslog daemon for logging. Facility is USER, levels are ERR, INFO and DEBUG.

If you experience problems with lcd4linux, always start it with lcd4linux -Fvv and send us the output!
