[Lubuntu] How to unmount a camera from the command line?

[Phill Whiteside]

Hi John,

from what you describe I think PCManFM is being maybe just a little too
eager to mount anything that arrives in a USB port. As such, I'd suggest
raising a bug against PCManFM in the first instance, it can always get
re-allocated once the dev-team have had chance to look into it.

Regards,

Phill.
