The only ones I have checked right now are: Volume manager Update notifier Restricted drivers and network manager I think technically you COULD turn them all off. I just turned off the visual one, so I don't know what it does. I will tell you if anything bad happens. I know the following were not there on the last version: bluetooth tracker (which i think takes a lot of resources) print queue (i think) users folders visual I think that the search (or tracker thing) and the name of the user on the panel (top panel on desktop) use a lot of resources. I took them off. They were not on the previous version. Also the various folders in the home directory were not there before either (music, videos, etc...). I only think the print queue would only be helpful if you print a lot one after another. I don't use it, and my pdf "printer" works fine. And... the network manager was added a couple of versions back (6.06 i think). At that time network manager had LOTS of bugs. I used to just disable it and configure my network manually wit >System >Administration >Network. I would disable "roaming mode"
