Question Tips for optimal experience running FC on laptop?

Hello everyone,

I am running FC11 on a Toshiba laptop with Celeron M CPU, 2 GB RAM and 250 GB SATA HD. Because this is a multiboot laptop, I would appreciate your letting me know which applications and services that are abssolutely not necessary so that I can leave them out.

Thanks a lot for your help.

Hello,

I think it would be hard for someone to tell you what is "not necessary" since we have no idea of what you do/use your laptop for.
You could start by turning off services that are not needed by you. You can see a list of enabled services by running this CLI as root:

Code:
chkconfig --list|grep on
and turn them off with the CLI:
Code:
chkconfig servicename off
You will probably want to check out System > Preferences > Startup Applications also.

That should give you a place to start. Hope this helps,

Ky

Re: Tips for optimal experience running FC on laptop?

Hi ky,

Thanks for your reply. Since I am using this laptop just for simple word processing, emails and casual Internet search, and because the machine has no line printer port, should I disable the following services?

1. cpuspeed
2. cups
3. ip6tables
4. nfs
5. sendmail
6. sshd
7. rpcbind
8. rpcgssd
9. rpcsvcgssd

Thanks a lot for your help.

As kyryder already said, nobody knows, what you are using your laptop for. I can tell you, what services I've explicitly disabled on my laptop:
1. avahi-daemon
2. bluetooth
3. livesys
4. livesys-late
5. sendmail
6. lvm2-monitor

Everything else is in default state, which may mean that it is disabled.

Hello,
I don't think you want to turn off cpuspeed and sendmail. cpuspeed helps conserve battery power by throttling your cpu when you don't need all its power(may also allow your cpu to run cooler) and sendmail is used to send you info( locally ) about possible problems with your machine ect. The rest of your list looks "killable". By just disabling the service will leave you the option to turn it back on if you find you need it.

Re: Tips for optimal experience running FC on laptop?

sendmail can kind of be a coin flip.

On the one hand, it's used as a local logging facility and, per its default configuration, will not even relay mail for any other machines. But, it's still used for logging and such. For that reason it's generally not "best practice" to disable it.

On the other hand, I've had it disabled on my netbook for months and the sun still rises and sets.

If in doubt, leave it on. It's not a huge resource-eater anyway.
