I am new to linux -- I typed arduino and got this:
blaise@king-desktop:~$ arduino
Experimental: JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version = RXTX-2.1-7
RXTX fhs_lock() Error: creating lock file: /var/lock/LCK..ttyUSB0: File exists
RXTX fhs_lock() Error: creating lock file: /var/lock/LCK..ttyUSB0: File exists
thats what you meant by start up message, correct?
It gives the same message for connected and unconnected arduino.
