Just a heads up...
I just downloaded and installed opencam and as soon as I clicked on the desktop shortcut it broke my ubuntu installation. I couldnt open any folders or open nautilus in terminal...and all the icons and folders disappeared from the desktop.
The ubuntu was a newly installed linux emc version with no modifications on my part. Luckily I have backups.
There isnt any documentation to the opencam software but I think it does some strange things to the ubuntu emc installation....?
