Thread: What services/packages can I remove to speed up my computer?

  1. #1

    Default What services/packages can I remove to speed up my computer?

    I just installed openSUSE 11.3 and I'm certain there are services and apps running that I do not need. So I was wondering if anyone here can help me find some to remove.

    My running services ("ps aux" - is there a better way to find the services running?):

    YaST offers a runlevel-editor, maybe you should give it a try, as the respective services are explained. We can not know what services you need - for example I do not own any bluetooth devices, therefore I deactivated 'bluez-coldplug', but you might still need it.

    By the way: the command 'ps' does not list services, but running processes. Quite a difference.

    And here's my packages:
    RAW OUTPUT 2U9sHK4X
    (And with highlighting/colors: XML | <entry kind="package" name - Packages - 2U9sHK4X - Pastebin.com )

    Those are packages and may or may not be a service.

    Only you can say what services you need or do not need. In general service on Linux do not significantly slow a machine. If you want to see what is using CPU cycles run the top command from the command line. Or via menu - system-monitor-System Monitor for a GUI

    And who is user 1000? You seem that have him running things, but having no username!

    I also have the idea that user root is running KDE. If that is true you can wait for big problem in no time. The simple question of running the avahi deamon or not is realy peanuts compares with what you are doing (did allready) to your system.

    Whoah! Why would that be? I just installed openSUSE 11.3 with all the defaults and the following:

    1. I am NOT an admin user (I'm logged in as a "regular" user account)
    2. My regular user account's password is diff. from root

    I only use root via sudo/su.

    And yes, who is user 1000? I just installed so everything is as the openSUSE installer set it up.

    1000 is the first user added to the system.

    Only the UID not the user name is displayed in pa aux command

    Root UID 1 does display as root.

    Thanks! What's going on with whathcvv said about KDE running under root? Is this bad? Why is it happening if so?

    Sorry I made you shiver. My fault.

    I did not see how you generated the list because that statement is not part of your copied pasted computer text (I hate people telling what they do, they must show what they do).

    I may be wrong about the root user having unneeded KDE processes also. There are one or two in my system, but not as much as in yours, but it still may be normal.

    In any case, forget my post above, but my advice still is (conclusion from other posts above): try to realy understand the differences between:
    . packages;
    . directories, files (all sorts like configuration, executable binaries, executable scripts, etc.) belonging to packages;
    . processes;
    . running network services;
    . start/stop scripts from /etc/.init.d and the whole complex around it including the concept of runlevels.

    There might be a few services that are switched on by default and which you do not need and thus can be switch off. After all the default is a compromise between what any openSUSE starter (and maybe noob) miigh think that will run "out of the box" and security.
    The use of YaST > System > System services (runlevel) will show the list. I switched off Avahi (for non zero network configuration, something you will not need when you do not have many MS systems in your LAN depending on it IIRC) and, as said above, sshd when you do not want to use it.

    Ask for any of those in the list of you have any doubts (of course after googling and/or looking in Wikipedia).

    Also, check if xinetd is running. When yes, check what it is serving there

    And last, when you do
    Code:
    netstat -atlp
    you will see what TCP ports are listening on your system. Same for UDP with
    Code:
    netstat -aulp
    These may btw still be blocked by your Firewall.
