Which Of These Services Can I Safely Turn Off?

3) OK, this was a slightly sardonic comment. To use disk space in a unixy system, the disks have to be mounted. You could potentially disable disk mounting in an embedded system that doesn't have disks, but for everyone else this is necessity.

You really don't want to be messing about tools for mounting and unmounting disks unless you know lots more about it than I do.

4) Cryptdisks is part of disk encryption; if you don't use disk encryption, you should be able to disable this. OTOH if you do use disk encryption, disabling this will lead to you being unable to access your data. Most people would regard this as a disadvantage.

Salasi, you've been very helpful.

1) As far as Cryptdisks is concerned, how can I found if I use disk encryption on my system?

2) What does Cryptdisks do? Is it important?

I can assure you that you do not need any services running in order to use Linux. Boot and shut down scripts does help simplify things. If you insist keeping some servicing running, I suggest the following.

dhcdbd
hal
rc.local
loopback
vboxdrv
vboxnet
x11-common

The service wpa-ifupd is only needed when you want to access encrypted wireless networks.

The services that you listed like the following can be disabled if you want to.

apparmor
hal - an optional service to run that helps with auto mounting storage devices
libpam-foreground - not really needed
mountoverflowtmp
policykit
powernowd
powernord.early
procps
rc.local - boot script
sysklogd - for logging and it is an optional service
ufw - might be Ubuntu firewall, but optional
wpa-ifupdown
x11-common - optional for X11 or X Window Server

You should look up the processes and scripts your self.

sundialsvcs, you are wrong. All services can be disabled and it will not mess up how Linux works.

Well, you probably only use disk encryption if you specified it at some time, probably when you installed your system. While I can't think of an obvious 'type this command' approach to discovering for certain whether you use encryption (maybe I would if I used encryption myself), but an alternative approach would be to take a look via a live CD and if you can still access your data normally then you are not using encryption.
