Ubuntu :: Xorg Nepomuk And Virtuos Take Most Of The Cpu?
May 29, 2010
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.
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I've already been through all the KDE documentation, and they're outdated when it comes to Akonadi and Nepomuk in Natty.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?
I loaded open suse 11.2 from download nothing works, an error comes up kde nepomuk not activated. And I cant do any thing in yast2, everything comes back to the error.
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 have a "nepomuk is not running" error message :"Nepomuk Indexing Agents Have Been isabled The Nepomuk service is not available or fully operational and attempts to rectify this have failed. Therefore indexing of all data stored in the Akonadi PIM service has been disabled, which will severely limit the capabilities of any application using this data.The following problems were detected:Nepomuk is not running."and also "nepomuk was not able to find the configured database backend 'redland'. Existing data can thus not be accessed ..."by the way while launching kontactt gives the following errors :mysql server journal with errorsnepomuk service not registered at D Busno ressource agents have been found
how nepomuk is supposed to work on opensuse 11.4 KDE? My nepomuk is active but it always says in "systemsettings" that 0 files are indexed. When I do a search via Dolphin, it never finds a file. It doesn't matter if I select "from here" or "everywhere". I also tried to select the root dir '/' to look for files to index, but still nepomuk says 0 files are indexed and dolphin finds nothing.
Nepomuk/strigi slowed my machine to a crawl and used 1Gb of disk space so I turned it off. In my machine is the same thing. Turning it off is a right and wise solution?
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?
Installed 11.3 as new install on Thinkpad T42. I now have a persistent notification "Nepomuk was not able to find the configured database backend 'redland' ... what it means. System seems to be working but desktop icons have grey vertical rectangular box when selected. No objects to select in the boxes though. Previous version had tools available as I recall.
I found in my xorg.0.log the the xorg ATI driver is failing ALL options.
Code: (WW) warning, (EE) error, (NI) not implemented, (??) unknown. [ 8.942] (WW) The directory "/usr/share/fonts/TTF/" does not exist. [ 8.942] (WW) The directory "/usr/share/fonts/OTF/" does not exist. [ 8.942] (WW) The directory "/usr/share/fonts/TTF/" does not exist.
I've just done a fresh install of Lubuntu 10.10 on an older Sony Vaio laptop. Having learned the hard way about editing xorg files, I wanted to create a backup of the xorg.conf file so that I dont have to do another install when I screw everything up. In a terminal, I typed
Alright setting up a friends netbook, display has been a little iffy (slow. glxgears is giving like 100fps). Couple issues: xorg.conf doesn't exist (i know thats typically not an issue) and "sudo xorg -configure" and "sudo xorg --configure" both return "xorg command not found."
glxinfo say that its using Mesa for the software rasterizer and that the driver is from mesa. lspci says the VGA controller is from Intel. I'm thinking xorg is defaulting to vesa for drivers, but I need to know how to change that to the open source intel driver
my laptop is running Slackware64 13.0. Today I tried to update to X.org 7.5 (version 1.7.1) from version 1.6.3 shipped with Slackware. I downloaded the relevant source tarballs from www.x.org and compiled them with no errors. The compiled packages are:
My laptop has an NVIDIA graphics card and I'm using the proprietary driver from NVIDIA. Thus I reinstalled the driver after the update and tried to launch X.org with "startx". After a short while the NVIDIA logo appears for some hundred milliseconds and disappears then. But now the screen is blank and it is not possible to switch to another VT via Ctrl+Alt+Fx. But it is possible to login from another computer and restart everything, so that I conclude that the system does not hang.
It is even possible to do work normally with the laptop from remote. If I try to kill the X-server, it ignores SIGTERM and has to be terminated by SIGKILL. But the laptop's screen stays black and empty and does not allow to switch to another VT (chvt terminates with "interrupted system call."). dmesg does not give any errors.
/var/log/Xorg.0.log:

I have installed Kubuntu 8.04.2 on a USB stick with persistence to keep any changes I make after a reboot and it works fine. I then installed the 185 Nvidia driver to give me higher resolutions and it works fine.
But each time I reboot, my updated xorg.conf is replaced with the default xorg.conf that ships with that version of Kubuntu and a backup is made of my updated xorg.conf (the correct one) which looks like xorg.conf.20100409135913. I have to put the backup xorg.conf back in place to get my Nvidia driver to work with the correct screen resolutions again. Otherwise my screen resolution is too low.
What could be causing this behavor? I'm sure it not the persistence feature of the USB stick failing since a backup is made of my original xorg.conf.
I might add more information. The xorg.conf that gets changed after a reboot says "This file was generated by dexconf, the Debian X Configuration tool, using # values from the debconf database." #
1. What is the difference between files (xorg.conf and xorg.conf-vesa)
2. No matter how hard I try I can't change keyboard layout in xorg.conf-vesa (I change it in file ) but there is no actually anything changing, it starts to get annoying - for example - below goes my xorg.conf-vesa, if I uncomment and set line from
I'm running the ubuntu based Green OS and cant get my video card properly configured. i've already gone through the forums to figure out what i need to do to get my ATI card working but my system wont let me access the xorg.conf file. i can see it using the the GOS file editor but it wont let me save the modifications. when i attempt to edit from a terminal window with su privelages it tells me that /etc/x11/xorg.conf does not exist. i've even tried booting into recovery mode and using the root instead of the sudo command. nothing i've tried will let me open the file.
I've read the how-tos (thank you oldcpu!) and wikis about how xorg.conf take precedence over the section configuration files in etc/X11/xorg.conf.d/, if it exist. I also understand that the xorg.conf can be partial. If it is missing some sections, these will be taken from the corresponding xorg.conf.d section config file. Currently I'm using a xorg.conf generated by nvidia-settings in one of my home machines, due to a dual-monitor setup. After generating xorg.conf, the device sections are:
My question is if the Option "UseCompositeWrapper" "True" will be used or not. In other words, if a section exist in xorg.conf then it's correspondent in xorg.conf.d/ will be completely ignored *or* only the lines in xorg.conf.d/ that already exist in xorg.conf will be ignored?
Just upgraded a desktop to openSUSE 11.4 with KDE, and I'm encountering various graphical problems. This machine's been running SUSE versions since 10.0 on similar hardware with few major issues, and I did the 'upgrade' by reinstalling the root partition and keeping the /home partition intact. It has a Radeon 9600 AGP card, which goes under the R300 and RV350AP monikers, and uses the radeon driver (too old for the proprietary ATI driver - deprecated). With the new KMS, it boots up fine under the monitor's correct resolution of 1440x900, though occasionally and randomly then drops to 1024x768 at the login screen. On occasions it will then arrive at the desktop under this lower resolution, other times it corrects itself before getting there.
On starting KDE, the taskbar cycles through various different settings (composited / non-composited) and colours with erroneous shadows. I've tried disabling desktop effects which at least resolves that particular issue. More troublesome is that certain actions result in a garbled display from which it is almost impossible to recover without guessing various keystrokes to cause a logout. Two examples are when running the regular (non-OpenGL) KDE slide show screen saver, when certain transformations corrupt the entire screen, and when opening the Tools -> Options dialog in LibreOffice, though strangely this only causes a problem under one user account and not another.
Running dmesg, I note it is being littered with:
Code:
[drm:radeon_vga_detect] *ERROR* VGA-1: probed a monitor but no|invalid EDID yet I have just the one VGA monitor which is VGA-0, and set as such under KDE. Not sure if that's related or a separate issue.I tried adding 'nomodeset' at boot, but it brings me to a console login and after entering 'startx' I get:
Code:
xauth: file /home/[user]/.serverauth.2891 does not exist
Fatal server error:
Cannot move old log file "/var/log/Xorg.0.log" to "/var/log/Xorg.0.log.old" xinit: giving up xinit: unable to connect to X server: Connection refused xinit: server error
[code]...
Booting in failsafe mode gets me into KDE but with other weirdness and problems using the desktop. I don't know if KMS is ultimately the culprit or there's some other obvious problem, but this is what I'm left with after a 'fresh' installation (despite the /home partition still being kept from openSUSE 11.3). It's not my PC so I need to leave it in a usable state knowing these corruptions aren't going to occur, and I leave the country next week.
I currently have one user logged in, and no applications open. My system is using 1.8G of ram, and my conky is showing that Xorg is using 22.92% of it... On a fresh boot, with one user logged in, it normally uses about 500 - 600mb. how to free up that ram? I was using Google Earth a minute ago (it's closed now)
First off my monitor is a 720p plasma, native resolution is 1024x768 and yes it's 16:9. Video is onboard ATI 4200 (AMD780G). and I've tried the fglrx, ati, and radeon drivers. So I would like my dpi settings to reflect that the pixels are longer horizontally (that there are less of them)
So i've been changing DisplaySize, and tweaking X with other options like [Option "NoDDC" "true"] etc. Nothing seems to change the display.
So then I check xdpyinfo and it reports what I have in X and it's what i've configured.. So I try wiping out X and seeing what it picks up and what do you know, it's auto-detecting everything fine.
Code: screen #0: dimensions: 1024x768 pixels (160x90 millimeters) resolution: 53x95 dots per inch
So the problem, it's not using these settings. I can change the DisplaySize to 1000 10 or 10 1000 and the display does not change, but xdpyinfo does correctly report what I've entered.
