Ubuntu :: Use The Nepomuk / Strigi File Indexing Service - Usability?
Aug 5, 2010
how one can use the nepomuk/strigi file indexing service. I started up dolphin, and typed the search string in the upper right corner, and clicked Search. The search result is a long list of files. The one I need is a PDF file. When I select this file, on the right hand side there is the following info: 'Is part of: 15.2 GiB Removable Media' which is clearly wrong, since this file resides in my home directory, which is on a 200 GiB partition. If I double-click this file to open in okular, I get an error message:
Code: Could not open nepomuksearch:/nepomuk_3A_2Fres_...... Reason: Please insert the removable medium "15.2 GiB Removable Media" to access this file I guess this is some old result from nepomuk's cache (in the meantime I have had to repartition my hard disk, and restore my home directory from a backup copy on an external hard drive - but this has been many months ago, so I would expect that nepomuk have had the time to recognize this)

I've had opensuse 11.2 for a long time and I've never seen this nepomuk thing run before. But all of a sudden on startup just now, I got a message that it was running. Why? What is this and should I be worried? Why have I never seen it before?

Code: Strigi service inizialization failed, maybe for an installation error. This is strange becouse during my installation I have not seen error messages....

On Windows, I used to be able to search for items on my home server quickly if it had indexing enabled by simpily typing a query in the search box when I was viewing one of its drives (i.e. samba shares).Since I moved the server to Ubuntu, I can find plenty of indexing software like tracker but I cant figure if any of them support querying them over the network. I need a fast way to search through all the files on the server with indexing without the hassle of having to VNC into it.

I have noticed on my netbook that F14 is running some sort of indexing service in the notification area. What is this, and how do I turn it off? I know what it is doing, but why is this just now important in F14. It is killing the battery life on my netbook.

I have a large number of video files on a couple of high capacity HDDs. The files are reasonably clearly named. I've never bothered creating a database of the files because I am inherently lazy and believe the computer should be doing this for me.
Anyways, crunch time. Had a look at the stuff in the public repositories, but they all involve too much typing, too much work. So, what are others using/ doing to maintain their "collection" indexes?

If I want to work on two or more non-maximised windows, how do I simply access their menus without having to select a window into focus and then go to the top main menu? I'm fairly impressed with Unity, but that really struck me as a major usability blunder. I can accept that the window has to brought into focus, because that's what you'd do anyway, but then having to move the mouse to the top of the screen to get at the menu options seems really off.
Is there a way of doing this that's as elegant as was the case previously?

I was running 10.10, and it was fine - except for some reason the mouse just stops working - nothing is clickable at all. Apparently this might be the official NVidia drivers, but I've not found a solution to that yet, but I do know that plenty of other people experience this. So today, I thought I'd check for updates to see if something would fix it.
1. I open the update manager, and see 11.04 is available, and several security fixes. I opt for the security fixes first, but they fail, saying 'check your internet connection'. My internet connection is perfectly fine, so this is a pretty bad error message to be showing people.
2. I then try the upgrade to 11.04 button instead, and it gets a small way in before saying it was 'unable to get exclusive lock' due to me having an update manager open - what, such as the one I used to launch this upgrade? Another bad error message.
3. I close everything, try again. Now it complains that not all upgrades can be installed due to a "previous upgrade that didn't complete". As a programmer I have to wonder why, if they're sensible enough to know how to use an exclusive lock to ensure a safe upgrade transaction, why they aren't sensible enough to treat the upgrade as a transaction which they could have rolled back when they failed to acquire that lock? Luckily this doesn't seem to be a serious problem but again it's a bad error message to display and one that is completely unnecessary.
4. I start upgrading. Eventually 'Defconf' pops up and asks me what I want to do about 'modified configuration file grub'? THIS IS NOT A SUITABLE QUESTION TO ASK A TYPICAL USER! My options are "Show differences, show side by side, show a 3 way comparison, do a 3 way merge (experimental), start a new shell to examine the situation, install the package maintainer's version, or keep the local version currently installed." Oh, while I'm doing this, the input periodically hangs every 10 seconds so I can't type. And I do have to type, because my mouse isn't working. Luckily, unlike 99% of computer users, I'm a programmer so I am not scared of comparing files, but I'm pretty horrified to see it pop up what looks like a text-based unified diff - how on earth is a normal human meant to act on that? And it did all this because it claimed I had changed something locally, but it became quite apparent on looking at the diff that I had done no such thing, and that some system program had done whatever it had done. So I was being asked about changes to a core piece of system functionality for no good reason.
5. I let it upgrade the file and it seemed to work when I rebooted. Now imagine my dismay when I notice that my desktop has been changed into a Mac. All my menus have disappeared and I have no idea how to get them back. I can still edit and reorder my menus in the System Settings but I'll be damned if I can work out how to get them on the screen again. Plus all my apps are uncomfortable to use now because the menus no longer appear unless I press the Alt key first. I'm not going to claim that the Mac approach is worse than what we had before but this is a MASSIVE usability change to spring on someone without any real warning or any guidance to simple things like "where did my menus and everything on them go?" I am aware most of this won't be news to most of you, but I'm sure that if you look at it from a pure usability perspective you can appreciate how awful an experience this would be for most people who now have to re-learn their system.

I recently decided to install ubuntu on an old PC to increase its speed and usability. Prior to this I had windows XP running on it. I installed the newest version of ubuntu, which makes the whole thing running unbearable slow. Under windows xp it was running ok, my question therefore is: which version would you guys recommend that needs less ressources, but still has comparable functionality to the new version?

from this multirow taskbar, extensible quicklaunch, clock day date are only important. And i want to doubleclick upper left corner of a window as alternative close. A better variant is to use the third wheel button on a mouse - to close any window just by pressing wheel inside a window (similar to Firefox close a tab, or in qip close a tab..)

I am doing a usability test on OpenSUSE 11.2 for a novice user. I am trying to establish if usability has an effect on why some students do not use GNU/Linux for general desktop computing. How easy and how many steps does a novice need to do the following tasks?
Note: Novice is someone who has no experience in working with OpenSUSE?
Task1: This task involves making two slides of a course presentation using OpenOffice Impress.Org
Task2: Involves changing the screen resolution and desktop background.
Task3: This task involves organizing files in folders
Task4: Involves copying music from an audio CD in to mp3 format using K3B
[code].....

I'm using Ubuntu 10.04 and I have a 1TB NTFS (internal) hard drive where I put all my files. The drive shows up in the "Places" menu, and if I select & open it, the drive and all the scripts & text files in it work. But, if I go to run the scripts without opening the dive in the places menu first, it just gives an error.
1. What is being done when I select the drive in the places menu?
2. Can this be set up automatically, so I don't have to open the drive every time after I start up?

I just upgraded Kubuntu from 9.10 to 10.04. I had problems getting Nepomuk and Strigi to run on 9.10, but finally did. I was using the Soprano backend on that version. Now, it seems that Virtuoso is the new backend, Ok?
I enabled Nepomuk, and Strigi, but the setting dialog in "System Settings / Advanced / Nepomuk" says that Strigi cannot start, could be an installation problem. When I expand the system tray, I see that the strigi icon is listed, and says it's scanning.
Is the warning in the System Settings incorrect, or is Strigi really not working properly? How can I check the status from the command line, and / or restart the daemon so I can read any errors on startup.

I just upgrade to KDE 4.3 and it is great release, one problem I have found with it is that The Strigi Desktop File Indexer does not want to start. The error that I get is "Strigi service failed to initialize, most likely due to an installation problem.", does anyone here know if Strigi logs things like this and were? "We must plan for freedom, and not only for security, if for no other reason than only freedom can make security more secure."

Whenever I boot up ubuntu, virtuoso-t, nepomukserver and 8 instances of a nepomukservices process run, and these DO really slow my system a lot, giving slow response of GUI apps etc... I tried asking before, but nobody knew. I'd like to keep trying: How can I get rid of these processes. What starts them up? I want to remove the command that starts them from which ever config file it is.
NOTE: disabling the desktop search setting in KDE settings does NOT disable these 10 executables that slow down your system. Going to KDE control center and disabling nepomuk there isn't the answer. I'd like to know the config file

I've installed KDE 4.6.2 (from Index of /repositories/KDE:/Release:/46/openSUSE_11.4) and I've noticed that Strigi fails to work. In my System Settings I have?message that Strigi haven't started, although it should (the checkbox to strart Srtigi is active). The process virtuoso-t is constantly suspended in the system.
OS: OpenSuse 11.4 64 bit. Some bugs are resolved in KDE 4.6.2 compared to 4.6.00, so I would like to stay with KDE 4.6.2.

The ?search engine thing 'strigi' is apparently slowing the computer down as it builds its index. The index is already up to about 2GB. This indexing has stared automatically after a new installation of Squeeze. The index is still being built a couple of days after the install. Assume the thing it's indexing is about 167 GB.
Should strigi be left to do its thing, or stopped? If so how?

I first installed strigi as part of nepomuk which came by default with my KDE 4 desktop. I noticed that nepomuk and virtuoso ended up consuming more than 1 GB of memory after a couple of hours, so I disabled it. I gave tracker a try, and after a couple of hours, it was using 300 mb. Left without options I installed the "under archiver" beagle. It has been running for many days keeping all my data indexed and up to date. The best part is that it uses mere 30 mb. The only change I did was enabling user_xattr on my file system, which as far as I know, doesn't affect tracker or strigi. Has anyone experienced this bizarre behavior with strigi or tracker? If so, is there a solution?

1. What file do i have to edit in order to include /usr/local/bin in the class path (ie. I put an executable in /usr/local/bin and when I try to execute it, it says the command cannot be found, etc.) EDIT: Solved, just didn't set PATH correctly. EDIT: New problem. When I try to execute a program in /usr/local/bin, it says "fopen: john.ini: File not found" Yet when i cd to /usr/local/bin, it doesn't say that. What would cause this?
2. Once I get my system setup the way i like it, how would i go about making it into a bootable CD/DVD?
3. How would I pass arguments from a shell script to a program?

Virtuoso neopomunk and xorg take most of the cpu while on indexing
Code:
1429 root 20 0 294m 96m 22m R 44 4.9 36:25.55 Xorg
1880 kirys 39 19 530m 47m 20m S 44 2.4 12:50.73 nepomukservices
1786 kirys 20 0 138m 45m 3336 S 30 2.3 15:39.85 virtuoso-t I can understand the complexity of the indexing but the cpu usage of xorg means to me that there is a lot of unnecessary refesh on the interface during the process even if there is no open dialog.

I receive following error when trying to enable strigi. "strigi service failed to initialize, most likely due to installation problem" I have searched internet, obviously not good enough, and i have found nothing. Nothing that would work. i have tried installing openjdk-devel as suggested, soprano. And still nothing. I have same problems on both boxes running Fedora 12.

I've already been through all the KDE documentation, and they're outdated when it comes to Akonadi and Nepomuk in Natty.
I've disabled Desktop Search in System Settings, which is supposed to disable Nepomuk. For some reason, nepomukserver and akonadiserver along with about twelve other memory-sucking processes autostart and have to be manually killed after my upgrade to Natty.
I can't simply remove all packages that contain akonadi in the name; one of its dependencies is kubuntu-desktop, which would suck to remove.

I'm not using any of the KDE PIM components (I already removed Kontact, KOrganizer, KMail, Kopete) but some akonadi tasks (~15-20) are always running in the background.How can I get rid of akonadi and nepomuk completely without removing the actual KDE desktop?
