What's with nepomuk?

It is eating up my cpu, usually at over 80%. I’m not even sure what it does. I found nothing here and google brings up nothing but praise for the miraculous semantic desktop provided by nepomuk. It seems to be a beagle replacement, on steroids.

My internet is slow. Firefox 3 is often unresponsive and the scrolling is slow or stalled. Some kde apps act the same way. Dolphin, for example, will not load quickly. When it does, it takes so long to respond to mouse clicks, I think it is stalled.

I’m running kde 4.1 and would normally blame plasma for all of this. But, every time I check, nepomuk is near or at the top of cpu usage.

do you need it?
did you install it?
how?
by rpm?
did you install the rpm with YaST?

  • if you installed it via YaST it should be a snap to uninstall with
    YaST, just click to see the trash can and then accept…

  • if you installed the rpm manually–do you now know the name of that
    rpm? if so just pop open a command line and type (as root)

rpm --erase [packageBlahBlah.rpm]

but, you may need some of the erase options…see man rpm

if you didn’t install it, how did it get on your machine?

Hi,

Did you also enable strigi? Strigi is still a bit buggy I think. I suggest to disable strigi (in nepomuk configuration). Maybe you want to use beagle instead :stuck_out_tongue:

hope this helps.

Just get rid of all this muk: nepomuk, stigi, beagle. It is not good enough.
It is the first thing I do after a clean install… delete !
Take Google desktop, it will work in the background without any noticable extra resources being used.
It seaches better and faster than any of these other progs.

Nepomuk is somthing they are working on for a future symantic desktop (whatever that may be).

No to all of these, except I don’t really know the answer to the first one. Monex asks about strigi. I did install that because it was supposed to be the greatest thing since sliced bread.

If I don’t need them, I’ll uninstall both. I have no problem using google. I just thought I could do without it and use only native linux apps.

same thing here: a process called nepomukservices uses up my CPU at times.
I read up on nepomuk, and it sounds really cool. Mine came with my first install. But I’m surprised there’s no doc about it: not even “man strigi” will return anything.
Has anyone been able to run searches with strigi? (the idea that one could search on audio file tags for instance really appeals to me

Ok. So, I went into yast to delete nepomuk and strigi. Turns out there is no nepomuk rpm but its in lots of stuff like kde runtime. A couple of the packages it was in could be updated, so I decided to update them.

I also looked to see if I could get rid of strigi. It has an rpm of its own but is also in other packages like kde runtime. Strigi packages also could be updated and when I clicked on one of them, here is the description

strigi is a very fast crawling, very small memory footprint, no hammering of the system with pluggable backend desktop search engine.

So. I updated those packages and now I’ll use it for awhile to see if it helped.

ok…i guess (since you never said) you are using KDE4–an animal i
have NO knowledge of…

if nepomuk and the other stuff you mention came built into KDE4, then
good luck with it…and, i retract my suggestion that your remove
those pieces…and, instead suggest: if you want stable and proven
KDE you should install and use KDE3…

you can have both (and use them one at a time: 4 when you wanna live
on the edge and WONDER why your CPU is eaten up, and 3 when you just
wanna get everything done without wondering.)

and, you might note that my original posting, second question was
“did you install it?” which you should have answered “no” (since it
came WITH your system) and never got to the point of actually trying
to delete it!!

you have to be REAL careful following the FREE advice given here by
the uninformed and/or ignorant (and i am both when it comes to KDE4)

ymmv

you should disable nepomuk and strigi
run systemsettings goto advanced tab
click nepomux/desktop search
uncheck enable nepomuk and enable strigi

Seems to me that desktop search is a niche…I really don’t ‘get it’ either.
Never found a need and if I have such a need it’s that ‘once in a blue moon’
case. I just hope it doesn’t get so intertwined that you can’t get rid of it
without unleashing dependency hell.

I have nepomuk enabled but strigi indexing off (I think this is default). It never eats up my cpu.

I don’t get desktop searching either. It’s like taking the Google approach to email where they encourage you to just have an abominable 7GB mess of an inbox and then provide you a search box to sift through it. I guess its helpful for people who don’t organize and just put files willy nilly on their desktops and home folders, but I find that simply organizing your files into directories is a much easier solution.

Updating hasn’t seemed to help. Next, I’ll try turning off the services.

@DenverD - I’ve tried doing the sensible thing, but I keep getting pulled to the flashy eye-candy of kde 4.1. Luckily, I never have to do real work. So, I can live with my mistakes :wink:

> Luckily, I never have to do real work. So, I can live with my mistakes :wink:

actually, the only time i do real work is when i play the
markets…and, then again when i do my own taxes…

more power to you comrade! :wink:

I can’t find where to turn off these services >:( They’re not in yast->system->runlevel services.

Browsing was so bad, I tried using konqueror instead of Firefox. Then, it occurred to me to try Alt+F2 and look at all the processes. Unlike TOP, there might be a process hog way down the list and, sure enough, I found strigi, nepomuk server and nepomukservices. However, they were sleeping and not using much memory. I killed them anyway.

Scrolling way down the list, I found 4 more instances of nepomukservices, one of which was using 73% of the cpu. I killed those and everything is running better.

This is not in Yast. This is purely KDE stuff. You will find it in ‘System Settings’; there is a ‘Nepomuk’ icon in the Advanced tab.
Uncheck both check boxes. Then after a reboot, these services (strigi and nepomuk) will no longer run.

Does anyone know how to take advantage of Nepomuk and/or Strigi?
