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:

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 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!
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 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 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.
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. Im running Ubuntu 10.10 2.6.35-25-generic x86_64 VGA compatible controller: nVidia Corporation G98M [GeForce G105M] (rev a2)
So basically, when I was using windows I got 25 second lag spikes 60 seconds inbetween eachother. Obviously this is a huge issue as I'm constantly doing things on the internet and I play a lot of games.
I used to use a program called WLAN Optimizer to kill these lag spikes, and it worked fine! However when I switched to Linux (Ubutu Natty Narwhal), I searched for hours and could find NOTHING on the subject. I tried using Playonlinux to get the program to load, but no such luck. I assume that's because it deals with advanced processes to eliminate the 25 second lag spikes. If anybody could help me get WLAN optimizer working, or simply find a work around that allows me to fix the lag, I would very VERY greatly appreciate it.
Otherwise I'm going to have switch back to vista, and I REALLY don't want to do that. I thought my comp was fried until I installed this OS because of Vista.
I've recently installed ubuntu on a 5,3 edition Macbook pro. It works amazingly and I love ubuntu but I have a small concern. Is it normal for the cpu usage to spike between 10% and sometimes over 70% but usually around 50%? I've ran the top command and its usually xorg, firefox or synaptic package manager causing the spikes. Is this cause for concern? Here is a screen of the cpu usage. When this screenshot was taken I had firefox open while upgrading to the latest version of Ubuntu. [URL]. However when I run OS X I'd have to be running many many programs, including CPU and plugin intensive programs such as Logic Pro with renoise slaved to it. Even with all of this CPU usage rarely goes past 40%.
I have a Ubuntu 10.04 LTS and about 40 ThinClients running LSTP in a school's computer lab. Everytime the users start to use applications, the server's memory utilization increases, while the swap memory is quite free. I have 12GB of memory on that server.
I wasn't sure weather to post here or on the minecraft forums.
OS: Ubuntu 11.04 x86 CPU: Intel core i5 sandy bridge 2410M GPU: Intel HD 3000 (Integrated) RAM: 8 gigs ddr3
So I got my new laptop a few days ago,loaded up ubuntu.After starting up minecraft to connect to my server I realised that the fps was going from 50 to 1 and back to 50 again EVERY SECOND so obviously this isn't normal.After a quick google search every one on windows seems to have no problem. There are no results for linux.
Edit: Yes I know why the are you using a x86 os on a computer with 8 gigs of ram? At the time of installation all I had was no internet access and a live cd from LUD with ubuntu on it
I was looking around in Xfce4 Taskmanager to see what's taking up some memory/processor power, and I noticed when I move the cursor around in cirlces, the CPU spikes from about 5%-10% clear up to about 40%. I also have Audacious2, Chromium, and a file manager open as well.
Why is this? My system is an Eee PC with a 1.6GHz Atom processor and 2GB of DDR2 RAM.
For the last several days my laptop has been "lagging". When typing (such as now) the cursor will disappear and no letters will appear for a second or I get doubling letters. Example: the word "laptop" will come out as "laaptoppp". When I hover the cursor over a link it will sometimes not highlight it right away. When I scroll up or down in Fire Fox or in my folders the screen will move a little, freeze, and then shoot down (or up) very quickly. Often Ctrl-c simply won't work. Plus several other things that all add up to being very frustrating.
I have the system monitor applet on a panel and I've noticed my CPU spiking periodically to 100%. When it happens it's rythmic, like this: A....A....A....A....A.... and then stops after a while. I've watched the processes and I'm fairly sure it's xorg doing it. My wife complained to me about her desktop doing similar things about a day before I saw that my laptop is doing this. I am fairly computer literate (no expert but no novice either) and I am totally stumped. Back in my Windows days (long, long ago in a...etc. etc.) I'd have said virus but here? Not so sure.
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 was trying to get the status of memory usage and disk usage using sigar in windows and ubuntu. done this in windows by just copying the sigar library into jdk library. But i was unable to do so in ubuntu. I've copied the library to java-6-sun library but still can't run the program.
I'm running into a problem where my system is running out of disk space on the root partition, but I can't figure out where the runaway usage is. I've had a stable system for a couple of years now, and it just ran out of space. I cleaned some files up to get the system workable again, but can't find the big usage area, and I'm getting conflicting results.For example, when I do a df it says I'm using 44GB out of 58 GB:
Code: [root@Zion ~]# df -h Filesystem Size Used Avail Use% Mounted on
Is there any way to monitor one process' CPU usage and RAM usage over time on Linux? I am trying to change to a cheaper VPS and need to work out what level of CPU and RAM I need!
I have to run this page: [URL].., because it fetches the content of some feeds(RSS) and then inserts into Database and then sends SMS texts to subscribed users. when i run it with php-cli in bash like this: php feeds.php?u=y&d=y
I only get: [4] 11719
but nothing happens, running it like this: black@loopserver:/var/www/loop/cp$ php 'feeds.php?u=y&d=y' Could not open input file: feeds.php?u=y&d=y
Can any one please tell me what to do? I think the problem is coming by passing get parameters, if i just run feeds.php everything goes fine, but I need to pass in those.
I want to use a script to renew my IP every 5 minutes. I have a static IP and it seems that when another person enter the same IP address as mine, my IP is stolen and is assigned to him.
I know that Cron is responsible for running a script at some time interval. How can I use that to renew my IP?
use kubuntu 9.10 64-bit on AMD Turion M500 machine.The network keeps disconnecting periodically or on some heavy activity The connection is totally stable on windows 7 though.My doubts point to network manager and so my next step is to switch to command line wpa_supplicant
I have an Ubuntu 10.04 installation that I have been using for about a month. However, just recently, at random times for about 5 seconds I can't use my mouse or keyboard.When it does that, the computer isn't frozen, I just can't type.About 5 seconds later, all the text that I was trying to type suddenly appears. I have 4GB or RAM, and even when I barely have any programs running and at 0% of resource usage, the problem still persists. This has just been happening for the past day or so.
I am not sure exactly what is going on, but my ASUS UL30a (X32a) keeps locking up until I press a key, then it seems to resume for a while.
At first I thought it was just the mouse, but I noticed that the screen stops refreshing also. Hitting the space key (or any other key) brings the systme back to life (until it happens again).
It is a fresh install of Ubuntu 10.10, not much seems to be going on in the top list (compiz 1%, xorg 0.5%)
I am looking for ways to try and diagnose the problem (if not fix it )
Do you know of any software that moves the files on my desktop periodically to set locations according to types mime types? For example, move all pictures to pictures folder or move all documents to documents folder.
I have a webcam that periodically gets dumped and I have to unplug and plug back in to get it to work again. I think it has to do with somethign about how the webcam is USB 2.0 but my PC is USB 1.0, even though it says it is USB 2.0. In Windows it would also dump it but then it would automatically remount it.
I have Apache, MySql server, and phpMyAdmin installed on my desktop. With the default installation of phpMyAdmin, I should be able to log in as root without a password. (Or at least every other time I have installed it, I could.) However, that isn't the case. I can't log in to phpMyAdmin period. I have tried setting the password for root with MySql through the terminal. Still no results. No matter what I do, when I try to log in to phpMyAdmin, I am denied access.
this is a fairly common issue (though I have never encountered it before) as I found similar posts in numerous forums, etc. I finally found a solution and now have it working. In case others have a similar problem, I am posting the solution that I used here. First open a terminal. Then use the following command
Code: mysqladmin -u root password NEWPASSWORD Substitute NEWPASSWORD with the password that you want to use and then you should be able to log in to phpMyAdmin as root with the new password.
Generally, my sound works in all applications and browsers...but every day or two, it suddenly quits and won't work again until I reboot. I am running Ubuntu 64, 8.10 and my mobo has a built-in sound card.
