CPU Usage in idle 18-23%...?

[vickoxy]

Hi,
i have dell mini 10v and i noticed that for last few days my cpu usage in idle (nothing is running) stays at 18-23%. Before that i had 9-10%.

Isn´t it little bit too much?

Ram stays low-at 140-170 MB

Running Ubuntu 9.10 (gnome) on Dell mini 10v. I installed HTOP too and it shows same usage...

In htop what is the app that is using the cpu so much?

[shaka_zulu]

check system activity and see what application "eats" processor?

[vickoxy]

smfpd is only app that i do not recognize-running at about 20%.
All other: cairo-dock, conky, gnome-terminal, htop, usr/bin/X... are having very low cpu usage.

What is this smfpd? In conky/system there is no sign of this process-i see it only in htop...

Ok, there is something-i installed yesterday samsung drivers an found that smfpd have something to do with it:

Is there any way to kill this process? Should it disable my printer?

[moetunes]

htop will show its' pid - process id
exit htop and enter - kill -15 "pid"

Well, in system activity there is nothing unususal. smfpd is not there- i can see it in htop eating 15-20%

And it has something to do with samsung drivers-that is some their daemon. Any idea how to remove it or shut it down?

htop will show its' pid - process id
exit htop and enter - kill -15 "pid"

That did, it, but after reboot-will it be there again? Is this permanent solution?

Thanks

I just printed one document. So, this smfpd is not necessary to have installed for printing (http://blog.rtg.in.ua/2009/09/what-is-smfpd.html), but can i disable this process or should i delete /usr/sbin/smfpd?

is there anything in the folder
/etc/init.d
that relates to it?

[vickoxy]

/etc/init.d

Yes there is:
/ets/init.d/smfpd -some Shell-Skript

and here:

/usr/sbin/smfpd -this is some x application

On this forum i found some other places where it could be:
http://ubuntuforums.org/showthread.php?t=341621

[vickoxy]

And yes-after reboot there is again this process running.

As said, i killed it and printing is working just fine without it..

But how to remove it permanently?

Thanks for help

[vickoxy]

Well, i removed those two files:
/etc/init.d/smfpd
/usr/sbin/smfpd

Have no problems at all with printing and my cpu usage at idle is now at 6-8% again. So, i will make this thread solved.

Thanks

I had this issue too. If you look at the contents of /etc/init.d/smfpd it shows you everything you need to know to "disable" it. Uncomment the "exit 0" like it says and you should be good.

sudo update-rc.d -f smfpd remove should do the trick.
