I recently retired a Dell M4400 laptop (that served well for about 7
years); its replacement is a Dell M4800... which came with a built-in
webcam:

I have installed:

devd is running:
g1-254(10.1-S)[84] service devd status
devd is running as pid 36061.

An attempt to just fire up webcamd doesn't actually seem to be useful:
g1-254(10.1-S)[86] service webcamd status
webcamd is not running.
g1-254(10.1-S)[87] service webcamd forcestart
Starting webcamd.
g1-254(10.1-S)[88] echo $?
0
g1-254(10.1-S)[89] service webcamd status
webcamd is not running.
g1-254(10.1-S)[90]=20
Getting webcamd to work isn't the most critical thing in the world,
but it would be kinda nice.
Any hints or clues for doing this?
Thanks!
Peace,
david
