Thanks all for the replies. To answer some questions: - I prefer automatic. I already have a key on my kb mapped to 'xlockmore -mode blank', but in some rare cases I still forget to do it, or I'm in an application that overrides the mapping and the key will not work. I'm using a DasKeyboard, that doesn't have any 'unused' keys like media stuff. I guess I'll look into the bluetooth thing. That looks quite doable.

Automatic screen lock when leaving desk
Hi, I'm looking for a way to automaticaly lock my X session when I leave my desk. Probably just using 'xlockmore -mode blank' or such. But how to detect? It could be infrared based (heat signature), video based (webcam w/ motion detection) or even mechanical (switch in seat? meh..). And how would FreeBSD interface with such device? Most likely via USB, since my lt doesn't have any serial ports. Any ideas?
