I have a system set up to do a autologin that runs a Perl program servicing an XBee and a USB camera to serve snapshot pictures. this boots and runs fine if I have a USB keyboard and a HTMI monitor. When I unplug (headless) them it does not seem to be working, as a little debugging aid I have a LED attached to the XBee that I turn off and on just to see of my code is running. I see no LED activity when headless.
Any ideas or suggestions?
