I have obtained an output file containing all the processes that my box is currently running. As someone who has a basic knowledge of linux i really don't know what processes I can kill. Can someone please tell me which of this process list are not needed to be running. I use my computer as a basic home PC i use the net, office software, play music, play dvds and print things. Almost everything i do can be covered by that
