OpenSUSE :: Regular Xorg And Plasma-desktop CPU Usage Spikes
Nov 1, 2010
I have this problem that Xorg CPU usage spikes to between %20-%40, a little more than once every second - constantly. When this happens, everything on the system slows down, video, scrolling through pages, etc. plasma-desktop does the same, at the same time as Xorg, though uses less CPU. Switching off Desktop effects makes no difference. The spikes starts just after KDE is up and running after boot. I'm running 11.3, KDE 4.4.4 release 3, 64bit on a desktop and 32bit on a laptop, both have the same problem. I have searched the internet, but cannot find anything related to this, please help!
My 64bit desktop details is:
hwinfo --short
cpu:
AMD Athlon(tm) 64 X2 Dual Core Processor 5400+, 1000 MHz
AMD Athlon(tm) 64 X2 Dual Core Processor 5400+, 1000 MHz

I just upgraded from Ubuntu 9.10 to 10.04 LTS, and my system seems to have developed a weird problem. Every few minutes, especially when I'm using chrome, VLC, or the screensaver is running, Xorg will start to spike in its CPU usage - spikes occur several times per second, and generally go up to 50-100%. Spikes seem to be composed of half "System" and half "User" according to my System Monitor applet thing.
Weirder than the problem is the thing which seems to stop this behavior - going to a terminal which is running top and hitting enter a few times seems to invariably return the CPU usage to usual (within seconds). There does seem to be a ~10 second period where the system monitor shows a few % "System" activity. Xorg starts up again with the same spikes within minutes, however.
EDIT: It looks like almost any keyboard input to any terminal also stops the Xorg CPU use - things which change the state of the other terminal, e.g. hitting the spacebar, typing a letter, will work, while hitting CTRL or SHIFT does not suffice to return the CPU use to normal.
I'm using an NVIDIA proprietary driver (which system->administration->hardware drivers says is (version current) and Recommended). My graphics card is a GeForce 9400 GT. I'm using Kernel 2.6.32-22-generic, and x86_64 Ubuntu. Here's my xorg.conf file:
Code:
# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings: version 1.0 (buildd@crested) Sun Feb 1 20:25:37 UTC 2009
# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig: version 1.0 (buildmeister@builder62) Tue Mar 24 06:15:32 PST 2009

When I "middle click" the scroll wheel to enable smooth scrolling in Firefox, the entire machine basically locks up until it scrolls to the bottom of the page. On a long web page, this can take almost a full minute as it scrolls very slowly.
Also, just using the scroll wheel to scroll normally. If I scroll up then back down quickly, it takes quite some time, and the CPU usage spikes under those conditions too.
As a test, I went ahead and loaded Top in a terminal window, set side-by-side with my browser. Once I start the smooth scrolling, I can't stop it. It has to get to the bottom of the web page to quit. Xorg's CPU usage spikes during that time and I can hear the fans starting to speed up.
I just quickly made a long text document in Gedit and tried scrolling through it. Same thing. So it's not limited to any one application.
Anyone experiencing anything like this? It started happening after my last major update.
I'm using Fedora 12 with Gnome.

I just upgraded KDE on my openSuSE 11.2 installation. I have never had any problems doing this in the past, but this time, when I rebooted, I noticed that after a few seconds of idle time, my CPU usage goes sky high. I ran top in a console and noticed the culprit was xorg. I am using an NVIDIA card on an AMD64 3200+ with 1 gig of memory. KDE version is currently 4.5.85.
Like I said, I didn't have this problem until the last update. Any ideas as to what could be causing this?

Recently I decided to install my first linux. I choose openSUSE. Installation went smooothly and everything seemed to work just fine. After few days i noticed that sometimes my screen blinks for some time. During this blinking everything is working very slow.Today when blinking started i decided to see CPU usage of specific processes and I noticed that during this strange behaviour Xorg CPU usage is about 40% or more, it seems odd to me because usually it is few %. I am wondering what is the cause of this behaviour and how can I do something about it.I am using KDE, my graphics card is Intel GMA 4500.

I have accidentally deleted the last desktop activity for Plasma. I cannot access the cashew and right clicking on the desktop does nothing. I can still see and use my panels just as I would before but there is nothing that I can put on the desktop do I get a desktop activity back from where there is nothing?

I'm running SUSE 11.3 32-bit and have run into an issue with the KDE Plasma Desktop crashing after login. I've submitted a bug report with the KDE folks, but thought it might be OpenSuSE specific. Details from the my KDE bug report [URL].. is as follows:
Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.2 (KDE 4.5.2)
Qt Version: 4.7.0
Operating System: Linux 2.6.34.7-0.4-desktop i686
Distribution: "openSUSE 11.3 (i586)"
Information about the crash: What I was doing when the application crashed: After updating my OpenSUSE 11.3 32-bit workstation to the latest (as of October 22, 4pm EST) available here:

I had openSuse 11.3 KDE4.4.4 installed and used the 1-Click install to get the nVidia drivers. However, this gave me the problems with Amarok and other applications crashing. I switched the system repos to use packman but that didn't help.
The solution on the forums seemed to be either recompile with an old nVidia driver or upgrade to KDE4.5 as most people were reporting to not see it under 4.5.
Upgrading seemed to be the easiest method, especially as there appeared to be a stable repo now.
I upgraded and now plasma-desktop crashes on login! Is getting the old nVidia driver my only option now?

I have been enjoying my newly installed openSuse installation for the past two weeks. I used it to run on a free computer I received so I didn't have to purchase that other operating system. It has come a long way since my last tinkering with linux/unix in college 12 years ago!I think that I noticed a problem with the calendar widget 1.0. When you change the month, the days don't update in the calendar.

I just updated both my KDE 3.5.10 and KDE 4.5 today (OpenSuse 1.11). The problem that I have now is that the Plasma Desktop is loaded automatically after KDE 3.5 has started. So, depending on where I click or what I do, plasma and kdesktop fight for the control of my desktop.
I searched in every corners of my KDE 3.5 --and a bit in KDE 4 since somebody forced kdm4 on me-- but I haven't found who or what starts "plasma-desktop". Definitively not me! I can kill it safely but that's very irritating.

I'm running OpenSUSE 11.4 (i586) with KDE Desktop 4.6.0 "release 6" on my IBM ThinPad X40. And I have trouble with getting new plasma widgets by internet. To be more concrete, every time I try to install new widget (first I want to view details of that), so when I'm pushing on blue button called "Details", BOOM and my plasma desktop crashes and after refreshing it generates the dump file for reporting to developers.
As this is quite an annoying bug, I've decided to report it, so I've installed all the necessary debugging tools, generated the complete bug report and sent it to KDE team. After this, I've got mail with link on KDE bug tracking system [URL] and found a lot of people being in the same trouble. So, one guy - Dario Andres (I think he's from KDE team) says: "The bug and the fix are in "libattica", may be your version of that library is not the latest. (or there wasn't a release including the fix)" and though after his comment there's a dozen of other replies with the same problem, all of them are marked as the duplicated bug and has no answer.
Well, even I know that my operating system is always up to dated, anyway I've checked that library version on my computer:
giorgi@linux-oary:~> rpm -qa|grep libattica
libattica0-0.2.0-5.1.i586
And I've double checked on the Internet and this is the latest version of this library. So, it's obvious that this BUG 261530 has not solved by this library.

I am finding that plasma-desktop crashes on a freshly installed 11.3 64-bit VM in VirtualBox whenever memory is set to 512MB. I created the VM with 1GB, which is overkill for what I am using it for. At that point all was well. After lowing memory to 512MB, it boots and starts to load the desktop, which fails - error log below. Increasing memory to 756MB allows it to load fine again.
I don't really need a desktop environment on this VM, but it seems odd this is happening at all. 512MB should be fine to run a basic VM with KDE and per Hardware requirements - openSUSE 256MB is the minimum, and 512MB is recommended.
While it's not a big deal, I am a bit curious why this really needs 756MB to run a bare bones system and just launch KDE. Really? We've come to that?
Perhaps I just long for the halcyon days when Linux would run, including a desktop environment, on a 486 with 256MB . . .

Is there a way in SuSE 11.1 to have the conventional desktop, instead the plasma desktop? I thought that installing KDE 3.5 will fix it, but I was wrong. I really don't want to download back SuSE 11.0, just to have my old desktop layout. SuSE developers should at least leave it as an option than to force people to install it

Running 3.3.2 of LibreOffice under 64bit 11.3. When I open a document (.doc) it opens right away, then the cpu spikes for about 8 seconds during which the app is not usable then all is fine. Renamed .libreoffice and made no difference. Tried with both .doc and .odf document types and the same. If I open a empty doc then the spike is a second or 2.

I am using OpenSUSE for the first time. I quite like it but KDE on 11.3 is really giving me a hard time. My desktop becomes very sluggish after about an hour of usage and the KDE widgets/desktop are no longer rendered properly, with color spilling and bloated borders etc.
To give you a better idea, here is a screenshot of my desktop -[url] here's another - [url]
I suspect that this might be an issue with drivers for Intel Graphics, though I couldn't find anyone experiencing exactly the same problem as me. I am running a P4 2.4 GHz with onboard intel graphics.

I use my second machine mainly as an xbmc box, but for the past few months it has come across a problem where if I idle for a certain period while running xbmc, eventually my Xorg process will basically hang, using 99% or more of my CPU. I can rescue my machine via ssh if I stop the gdm service and then kill the Xorg process, but re-starting gdm will cause Xorg to immediately use 99% again, even if xbmc is no longer running.
This will invariably occur if xbmc is running, and never occurs if not. I believe sometimes it also will happen if I am actually using xbmc, but usually it happens when idling. I have tried changing the screen saver to a blank screen, thinking that maybe the screen saver was causing some kind of graphics driver problem, to no avail.
I understand if this should be posted at the xbmc problems but the fact that the problem persists after shutting down xbmc and restarting gdm/Xorg suggests to me that something is going awry outside of xbmc. The logs for both xbmc and Xorg do not reveal anything that would suggest why things would all of a sudden break.
I am running xbmc on a retired mythbuntu installation, x86_64, which has had most of the myth stuff removed. I already disabled/uninstalled pulseaudio and compiz. This phenomenon occured all way way back with Gutsy Gibbon and I have since tried every upgrade in between, now on Lucid Lynx. I have also tried with both stable and daily SVN builds of xbmc.
Any ideas on where I might start debugging this problem? What is confusing to me is that xbmc seems to be stable, and so does Xorg. If I had to guess it would be a driver issue, though I have also tried multiple versions of the Nvidia driver as well (currently using 195.36.07.03).

I recently made the final jump over to Linux and am using OpenSUSE 11.2 KDE 4 on my laptop while waiting for my companies to get new computers, which will probably be running Ubuntu.
So I've got OpenSUSE set up and running great, but twice in a row I've had strange crashes: Once last night and once today. It seems like my plasma desktop dies. This is what happens:
- Desktop 1 (my main working desktop) suddenly has a different background and I have no options to work with the plasma desktop stuff I usually have on it (I've got the Marble satellite picture of the world). Instead, all the icons look a lot more old-fashioned, like a friend of mine's GNOME desktop (not meant as a dig against GNOME, just an observation).
- The other desktops have a pure black background.
- My task bar and everything on it's gone - no clock, no programs, no kicker menu
- Alt+F1 doesn't do anything any more
- Ctrl+Alt+Delete doesn't do anything, to shut down I have to use the terminal
Things that do work:
- Alt+F2 to call up programs
- Switching between desktops with keyboard shortcuts (my pager's gone)
- Zooming out to see my desktops with Ctrl+F8
I've managed to identify the following factors that might contribute to the crash:
- Something similar happened when I shut down my computer while connected to an external monitor, but my desktop background wasn't gone and the plasma desktop functions were there, I just didn't want to bother putting together a new taskbar. The problem there (and this occurs consistently) was that, if I move my task bar to the external monitor and don't move it back before disconnecting from the monitor, SUSE leaves it there until I come back to the monitor again. THEN I can move my taskbar back. Workaround: I always leave my taskbar on my desktop screen. Maybe room for improvement in the next version? Like I said, though, this problem isn't entirely like the one I've got here.
- Both times I was making a system backup and saving it to an external hard drive. That seems to use a lot of system resources and that's when everything went wrong.
- This time I was working with OpenOffice Writer and suddenly my desktop, etc. was gone after viewing a second presentation in Impress. I was able to close down Impress, but Writer died when I tried to close and save. I still can't get the window closed, but it won't update either. I tried using Ctrl+Esc and that let me kill the process, but a couple minutes after that Ctrl+Esc stopped working too.
This time, the crash occured after calling up a presentation in Impress. Last time it was after connecting an external hard drive.

I had Fedora 10 running for since its release, was planning to skip Fedora 11. Well, I shorted my first RAID drive. Was unrepairable. Therefore I installed Fedora 11. I can not find the comic strips options in the KDE Desktop Plasma thingy, upper right of your screen. Used to read UserFriendly, Snoopy and Garfield daily.

I have Fedora 11 64bit installed and using KDE with all the updates . I noticed that after a few days of work the plasma-desktop process is eating abnormal quantities of memory - resident size can grow up to 1 GB, by then KDE gets so unresponsive that you have to restart the session anyway.
I don't use desktop effects and no plasmoids either (even got rid of the folder view of desktop), the graphics are Intel 82Q35 Express Integrated Graphics Controller with the default (intel) driver. I have dual monitor setup (1600x1200 and 1024x786), to get them work correctly I had to come up with a custom xorg.conf and xrandr (if someone thinks xorg.conf contents can be relevant, I can post them, too).
I've seen reports of memory leaks in versions 4.2, but none so severe as is my case.
Below is the top command (sorted by RSS) after just 5 days of usage, showing plasma-desktop consuming growing towards 500MB:
How to stop it consuming so much RAM? This is a real annoyance, since it slows down the whole machine because of induced swapping.

After the recent upgrade to Lucid, my gnome session is working fine, but my kde session leaves much to be desired. Basically the plasma desktop is not showing up.
I am seeing plasma-desktop in synaptic unchecked and in the process of installing it.
Why was it removed in the first place and will it show up now?
Will report back after a reboot.

I had a bad surprise today as I tried to start my Kubuntu: plasma-desktop segfaults when I try to start a graphical session (and I get into a black screen with a mouse that I can move, and I do get a notification for new updates appearing at the top of the screen, but that's all)... I can still login to console, but startx won't solve the issue. That's quite a serious issue and I can't find a workaround for now.

I recently switched from jessie to stretch on both i encountered a jerky ui in gnome 3. after a longer research i noticed xorg consumes over 80% of my first cpu-core while moving a window. for testing purposes i switched back to the nouveau driver and there is no high cpu usage while moving a window, also the ui is smooth.
i tried 3 different nvidia driver: the one from the debian repository, the current stable and beta driver from the nvidia site. i noticed on all 3 the same problem.

I have just started to have a problem with Xorg it is always using at least 30% of my CPU, and the whole system does not run smooth so if I play a video it does not run smooth, it judders, also even if I drag an icon it judders across the screen.

after the upgrade to Constantine I have a strange behaviour with plasma. The whole desktop freezes when a plasma widget pops up - like opening the menu or plugging in a disk and the mount options are shown. The X server still runs fine (Mouse and Keyboard are still working). Afterwards everything works fine again, I can even use the widget. I also tried a fresh install, and with the noveau driver the problem wasn't there, only after I installed the nvidia driver the problem reappeared again. Desktop effects are diabled. When I try killing plasma-desktop and restarting it from the command line, the desktop also freezes for a short time again, and I get teh following output:

I couldn't find anything helpful in Xorg.0.log or dmesg/syslog. I used nvidia-settings to configure xorg. I have a nvidia 6600 GT. If you need more infos just ask.

When i run the KDE 4.6.1 netbook plasma desktop, there's a icon in the right upper corner telling how many applications i've running. When I click it, the desktop zooms out and shows me the applications in a graphical way, wich is pretty nice....but...then i can not select an application to switch to and have to wait a certain time out to go back to the running program i had in the foreground allready.
When i change the settings of this icon to show it always in a menu, it does work allright (but is less nice)..

Plasma-desktop crashes when trying to right-click on any icon or when trying to drug 'n' drop any file(on the desktop) in any folder.-But no trouble when right-click on the bare desktop-in order to the background pic for examble-.A possible explanation could be a fault on the upgrade packages as I had no trouble few days ago.

Is there anyway to run KDE without Plasma?At install I opted out of the kdebase-workspace package, but then didn't have the xwmconfig option to run KDE.Duplicating, then commenting out the original, and on the uncommented line: removing everything after 'Exec='. Taking the 'plasma.desktop' out. ...Deleting the entire file will only get it rewritten again by the system..Now it loads into beautiful void.I still have my GUI, complete with any kApps you might want: konsole, konqueror, and even krunner; but no panels or Desktop Activities.Is it still loading plasma only no longer implementing it? Am I losing precious RAM'CPU usage with plasma getting loaded without being used?

I have a desktop PC that I built back when I was a teenager, running Ubuntu 10.04 LTS and nothing else. I love it, but for one thing: the dang CPU usage hits at least 99% whenever any application besides Xorg is open and running. This doesn't affect performance too much, but if Windows XP Home Edition never gets close to 100% usage, then I figure there's something going on.
