Don't run compiz, either. I have been going through the processes,
though. I notice /usr/bin/pads is running. I have no idea why, though. I
looked it up on the Ubu site, but I never installed it nor launched it!
"Pads is a signature based detection engine used to passively detect
network assets. It can determine which systems are alive in the network
as well as the services they make use of. It is designed to complement
IDS technology by providing context to IDS alerts. Unlike other tools,
like nmap, it will not generate any network traffic which makes it
useful to run both on network capture files and promiscuous mode
interfaces."
