Default Re: Nvidia 9600GT: Xorg process and high CPU usage

I would like to mention that I am experiencing the exact same issues and they are really getting on my nerves. I have tried a lot of searching to find the cause of this problem.

To really see just how much this is bothering me take a look at this thread that I made to the XOrg guys in an attempt to get them to help me.

I have no idea why this is happening but I would really like to get to the bottom of the problem. I have attached a bug report to this issue but I would like to note that the bug report was generated when the issue in question was NOT happening.

I will come back to see updated posts and to submit a better bug report when the actual issue happens again.

Did any of you try disabling the composite extension in your xorg.conf? What about also starting with a clean xorg.conf

As an extra note, I still get high Xorg cpu (80-100% for one core) when resizing Dolphin when it's looking at +-100 files or directories.

In other situations, it's workable but I'm sure that performance of the NVidia 9600 can do much better than this. Hopefully the driver and/or xorg will get an update soon to fix this.

Tried it, but it had no measurable effect in my case. Also, disabling all kde eye-candy didn't make any significant difference.

Default Re: Nvidia 9600GT: Xorg process and high CPU usage

I am running (now) a GeForce 8400GS with OpenSuSE 11.4 and Nouveau (Open source Nvidia driver). I had been running the NVidia driver (level I don't have now as I fully uninstalled and deleted it). My CPU is an AMD Athlon 64 X2 Dual Core 4200+ and I have 8GB of RAM. While running a monitor to watch this, memory and swap usage do not seem to change all that much.

Let me confirm some things that have already been posted.

If I let the machine sit here, bootted up and signed on as a user with Firefox and Gnome Sysmonitor running withi top, and come back to it the next day, it is slow. If I allow it to just sit like this for two days, Xorg will be eating so much of one core (as in 100%) that firefox is non-responsive.

Reboot the machine and do some simple work with Open Office writing a document and working with a spreadsheet and Firefox and within 1.5 hours you will notice jerky response. Look at top and there's xorg peaking at over 80%, and one is not really doing anything.

So, it would seem that if this problem is this easy to recreate using OpenSuSE 11.4 with the NVidia driver, but not the Noveau driver, then those who do NVidiea driver work shouldn't have a major big deal with recreating this.

Would running a wallpaper changer (that changes the wall paper every 15 minutes or so) really contribute to this, or actually be the cause? If that is the case, why doesn't it cause the problem under the open source graphics driver?

Default Re: Nvidia 9600GT: Xorg process and high CPU usage

After upgrading my Debian from stable to testing, xorg is now less of a problem. However, the problem has not completely gone away and in some cases the cpu usage is still extreme.

Dolphine seems to work fine now, even with many folders and files in one view.

Let's start Firefox/Iceweasel and visit a twitter account page, for instance
http://twitter.com/#!/linustorvalds Xorg cpu will reach 100% within seconds. Thing is, when I'm using Chrome, everything runs smooth.

Let's start amarok.... 100% cpu usage for xorg within seconds.

Some version info:
xorg 1:7.6+8
xserver-xorg 1:7.6+8
nvidia driver 285.03
firefox/iceweasel 6.0.2-1
amarok-common 2.4.3-1

May this info can help a bit in looking for a solution.

Another way to reproduce:

Use Dolphin (or Konqueror), copy a few large files (in my case 2-4GB per file) and xorg cpu usage will go to 100% for one core instantly.

When copying at the command line, this does not happen.

Default Re: Nvidia 9600GT: Xorg process and high CPU usage

I also see this. I also note that Xorg memory use ramps over a couple of days from 600MB to 1.3G.
Then the desktop becomes unusable, and a reboot is required.
I have tried numerous configurations and tweaks via nvidia-settings, to no avail.

The stock kernel (as opposed to desktop kernel) suffers from the same problem.

Please advise what information can I provide to help debug this - I really want this fixed since the interface is so nice to use after rebooting, but I thought regular reboots were not needed for linux!

Software
--------
OS: opensuse 11.4 (64bit)
xorg-x11: 7.5
nividia: 275.21

Hardware:
----------
Quadro FX 1800
6GB system memory
4 core Xeon X5450 @ 3GHz

Configuration:
-------------
Twinview (2x 1600x1200)
KDE 4.6.0
Everything is "stock" opensuse

I have also seen this on an opensuse 11.3 machine with a single monitor and nvidia card.

Default Re: Nvidia 9600GT: Xorg process and high CPU usage

I am still encountering this problem and I do not know what to do to fix it. I am currently running driver version 285.03. Honestly, at this point I am willing to setup my machine so that one of the nvidia devs can ssh into it and take a look at what is going on.

I am going to try and upgrade to the latest prerelease version now but It does not seem like the problem is going to solve itself.

Though for the first time ever just then the CPU usage just went back down after going up. I am so confused, I have no idea why X is doing that. It was just high for about twenty minutes.

Default Re: Nvidia 9600GT: Xorg process and high CPU usage

Hi have monitored Xorg memory use every hour, and see huge jumps for no obvious reason. Some jumps occur when I was definately only using firefox (ff was ALREADY running, but I visited 3 new sites in different tabs).
Does this help???

Default Re: Nvidia 9600GT: Xorg process and high CPU usage

VGA compatible controller: nVidia Corporation G96 [GeForce 9500 GT] (rev a1)
Intel(R) Core(TM)2 Quad CPU Q8200 @ 2.33GHz
I have the same problem on Debian Testing after a recent upgrade. The version of the nvidia driver I was using is this:
xserver-xorg-video-nvidia Version: 280.13.really.275.28-1

After downloading the binary driver from the nvidia website (NVIDIA-Linux-x86_64-285.05.09)
and uninstalling all of the debian nvidia stuff (apt-get remove nvidia-installer-cleanup),
It was better, but 2 more options to switch on in xorg.conf helped too, as per the suggestion here:

http://www.makeuseof.com/answers/xor...nux-fedora-12/

Option “RenderAccel” “on”
Option “UseEvents” “on”

End result: Things are a bit better, but I still end up seeing my whole desktop grind to a halt especially when running GTK+ based apps such as firefox, thunderbird, and openoffice.

The culprit is always xorg at 100%.

When this happens, I have to wait multiple seconds for a response to my keyboard or mouse clicks.
I disabled all desktop effects. I am using KDE by the way.
