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)
View 5 RepliesI 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?
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.

For some reason after I close firefox , firefox-bin keeps running and it eats more cpu than when firefox was open, a lot more. Same thing with seamonkey, seamonkey-bin keeps running after it is closed.
Attached are two pictures ,
1) While firefox is running: notice the low CPU usage
2) Firefox closed, CPU is almost 50%
I am running Apache 2.2.3 on a CentOS release 5.3 (Final) with 100 Sites. I've notice that Apache is making my server Swap around 200 MBs.
"http://www.xxx.yyy.zzz/server-status" doesn't show me too much to, so I am looking the behavior of specific httpd process.
ProcessID "18753" is the one for "http://www.xxx.yyy.zzz/server-status" in my browser.
This command show me (In KBs) how much virtual memory is that specific process using:
# /etc/init.d/httpd start
# grep Private_Dirty /proc/18753/smaps | awk '{ print $2 }' | xargs ruby -e 'puts ARGV.inject { |i, j| i.to_i + j.to_i }'
3012
... Running this command a lot of times it gives me the same output, but suddenly...
# grep Private_Dirty /proc/18753/smaps | awk '{ print $2 }' | xargs ruby -e 'puts ARGV.inject { |i, j| i.to_i + j.to_i }'
21708
Something make that process (and all the others httpd process too) to use a lot more memory!
Part of my httpd.conf:
# Timeout 120
KeepAlive On
MaxKeepAliveRequests 100
KeepAliveTimeout 3

My server is running Mysql 5.1.34, vsftpd 2.0.5, BIND 9.3.4-P1 (as slave). I couldn't found anything running in the specific time that httpd processes start to use that much memory.
I upgraded my Asus Eeepc 900a to 10.4 yesterday. Since then, Xorg has averaged between 30-40% CPU, and my fans have gone nuts running high/low/high/low, ad nausium.
Any ideas what might be going on? Another clue perhaps: on reboot or shutdown, I get a "program not responding" message with "unknown" as the hung program. I have not been able to determine what this program is or if it is related to the hyperactive Xorg.

After changing servers and moving things around, I have one system which serves the /home directories, and for some reason, it is extremely slow. I've looked for duplicate IPs, signs of a HW problem, etc. and cannot figure out why the system is running with a high load, high iowaits, and low responsiveness. The servers and clients are slackware 12.2 and 13.1 respectively.
View 3 Replies View RelatedI have been using ubuntu for 4 years now on my decent laptop with 2 Gb RAM, dual core centrino, etc etc. Yet, in all those years I have been using this superior OS, I still have to do hard shutdowns because some program runs wild. I have lately 2 scenarios where I have to interfere with the process:
1: amarok crashes and leaves the python script for the gnome shortcut keys running at 100% CPU. Or: thunderbird-bin keeps running after apparently clean close of Thunderbird. That's not really bothering me, I just kill both processes.
The bigger problem is scenario 2: 2: VLC starts eating all my RAM (for no reason), my SWAP starts filling and my computer becomes unusable for 10 minutes. Or: my matlab script is too big and eats up too much RAM -> same. Note: I have nothing against SWAP because at many other times it's very useful
These are stupid and annoying problems where there is an easy solution:
1) automatically kill the stupid process that runs at 100% CPU
2) automatically kill the stupid process that eats up all my RAM

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.

Basically I have a machine with 16GB of RAM and have just discovered that using all of it can crash the whole system over one process. How could I run a process on the system in such a way that if more than 90% of system memory is used, the process immediately crashes?
View 3 Replies View RelatedI need to find the memory usage of a shared library loaded in Linux environment.
I need this information for deciding on whether to make the library part in to application or a seperate application itself.
I am running 10.10 on a netbook (1.6Ghz Atom N270, 2GB RAM). Because it has limited resources, I am currently testing to see which apps I want to use.
Which should take more priority -- an application that uses less RAM or an application that uses less CPU?
My problem is extremely slow write on hard disk and 100% cpu usage and it happens when I want to write something on the hard derive not any other external derive.
Tried a fresh ubuntu install. No change. I am not even sure if it is a software or hardware problem.
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!

View 3 Replies View RelatedI was doing some research on SSDs in wikipedia. Then it was showing me links to like DRAM and SRAM. Then there was RAM which I was familiar with. Anyways down to the point.The way your computer works is. When you start up your computer. Whatever is read on the hardrive is put on your RAM memory right.? For temporary and when you start applications. It is put in your RAM from your drive to run faster. This is why having ALOT of ram is useful for having your computer running smoothly. Right?

View 3 Replies View RelatedSeveral times in the last few days the desktop has frozen. I don't know if it's KDE issue or another conflict.All programs seem to continue running smoothly, but none of the menus on windows will work, or anything in the task manager, or desktop itself. I've tried killing the task manager but it doesn't affect the issue. If I knew what process was causing this, I might be able to restart it.
View 9 Replies View RelatedAfter I had upgraded to 10.10, Firefox was at first running smoothly, but later it would no longer connect/open any given site. (could not connect to server). I the de-installed and new installed Firefox and it worked fine again for a while but then the same problem returned. I then completely removed Firefox and all packages pertaining to it, and then made a new install of the basic Firefox browser (same problem), then started adding one by one the other "Ubuntu" packages in synaptic for firefox, but the problem remains. I am currently using Chromium (which runs well and extremely fast) but I would like to have Firefox back
View 3 Replies View RelatedI'm running desktop machine with with a core2 duo E6400 with 2GB RAM. I have completed a fresh install of Ubuntu 9.10 (fully updated). I have 10GB root, 2GB swap, 10GB home and 80GB data parititons.
I log in to main administrator account (first boot), create a new user (desktop) account and then use the switch user to log into the desktop account (so logged in to two accounts at the same time).
Whilst logged into the desktop account the CPU usage as seen in system monitor shows the two CPU's alternating at around 100% and the system slows down greatly.
Ubuntu 9.04 64-bit I just checked my system monitor and it looks like my memory is at a constant 900 MB's out of 4 gigs of ram. This seems high for only having firefox open.
View 5 Replies View RelatedI have recently upgraded from Kubuntu 9.10 to 10.04. I am having trouble with CPU usage by the X server. When running KDE programs (for example Kontact and Amarok) my computer is becoming very sluggish. This seems to be because X is using 90-100% of the CPU constantly when there are any changes to the application (any sort of redraw, even the mouse moving across the screen). I don't experience this with other applications (I am currently writing this from Chromium with no issues at all). Below is all the relevant information I can think to include.
INSTALL PROCESS: Fresh install from Ubuntu 10.04 LiveCD. My /home direrctory is on a separate partition so that has remained unchanged from 9.10. After installing Ubuntu, I installed the kubuntu-desktop package to install kdm and the KDE desktop.
The only real change from my last install is that /var is now also a separate partition (in a bid to save my MySQL data should I have to reinstall again) but it is on the same hard drive as my root partition and so shouldn't be causing any performance issues.
MY X SETUP: Three screen setup using onboard and PCI graphics cards. This worked perfectly before and, after reconfiguring X using nvidia-xconfig works almost as well again. Except that one of my monitors autodetects at 1280x1024 where before it was a higher (and widescreen) resolution.
The issue only presents itself when KDE application screens are visible and disappears when they are hidden (either minimised or closed) As far as Ican tell it could be an X, Qt or KDE issue. But I am not sure what versions of these will have been changed in the upgrade.
My problem seems to be very simple, it's high memory usage. I occasionally will use movie player to watch a few shows and I use firefox as well. My memory usage starts out real small about 500 mb but after using firefox lightly and movie player it jumps to almost 2 gigs and this is after they've been closed what gives? I've attached an image so you can see what I'm talking about.
View 7 Replies View RelatedI don't understand why I have a 800MB usage at startup. I didn't add any programs to start at startup. I do though have 10 primary partitions that are auto mounted at startup but it shouldn't use up so much, I have 2GB total RAM.
At startup nautilus uses ~400MB of virtual memory in the "system monitor"
Also which is RAM and which is SWAP in resources in system monitor: Virtual Memory && Memory?
-i figure vm is ram but thats not possible sometimes...it exceeds 2GB
I play RuneScape most of the time i'm on the computer and i always keep an eye on the performance. Yesterday and the days before, everything was going good, cpu usage it was causing was between 30 and 60%, now it wont go below 70%. It's always 70-99% for some reason :s i have set settings for graphics to OpenGL (they were like that before too with no problem) and it started causing high cpu usage. If i set it to Safe Mode in graphics settings it gets 100%, I never tweaked the drivers, i have a NVIDIA GeForce 9600 GT, i have the opengl thingies installed along with my nvidia driver. Ubuntu 10.10 32bit.
