Compiz runs almost at 100% and the system is slow, what can I do?

  • 772

My system became very slow out of the sudden, yesterday Compiz was running extremely smooth, today it started working very slow and slowing the computer.

What I've done so far was to resize my swap partition to 6 gigabytes (my computer has 3 gigabytes of RAM), before it was on 5.1 gigabytes, so I though that was the reason of this but still not.

Also I tested running only metacity by running metacity --replace and also with Mutter. With metacity works really great no problem but, in the other hand, with mutter the computer works slower than running compiz instead.

I am using the Nvidia driver version 173.14.28 and my X Server version as reports the NVidia X Server Settings is the 11.0.

My Linux kernel running on this computer is 2.6.35-25-generic and my ubuntu version is 10.10.

Any help will be appreciated.

  1. To narrow down the likely sources of problems, create a new user (System/Administration/Users and Groups) and log in as that new user. If it works, the original problem is related to your user configuration - your compiz settings, perhaps. If it's still broken, it's a system-wide problem and presumably related to an update or something else that changed in the system. You could check what updates, if any, you installed lately.

  2. Although I am not using 10.10 and neither same version of kernel, but during those days when I was using 9.10 with nVidia driver and Compiz on, I do have this issue before.

    What I did was I choose to run nVidia with Vdpau using the following PPA:

    Make sure you backup all data before trying this. Use at own risk.

  3. I had a similar problem some times ago and in my case it was related to compiz version and video driver version. Are you sure you didn't updated one or the other ?

    You could also try to start compiz from a terminal (just type compiz), that may show you some warning message that is invisible otherwise. In my case there was such message (sorry I can't exactly remember what it said) and the problem was indeed related to that.

  4. I know this is an old thread but I today had this problem with compiz taking up all cpu resources and came to the conclusion that the reason was that I just installed gnome-panel (just gnome-panel without any dependencies/suggested applications). I uninstalled gnome-panel and that fixed the issue.
