    Ubuntu uses Unity as its default desktop environment, which allows the use of an OpenGL library called compiz when rendering graphics. However, after improvement, you will find that our compiz process is overloading the processor, even if your system is most likely idle. The load will be at this peak if you open a graphics intensive application such as a web browser.

    The last update to 14.04 allowed Compiz to put a heavy load on the processor. When I run top I see it grows larger as I drive up to the dock and when I focus on Sublime if you want Emacs or Gedit it helps you 50% or less. As soon as the returnI focus on the shell, everything drops by a few%.

    I had to run 14.04 LTS on Parallels 10 for months without this nightmare, and run it right after the last update.

    Why does Ubuntu use so much CPU when it is idle?

    Ubuntu uses Unity as its default desktop environment, which typically uses an OpenGL library called compiz to render graphics. However, immediately after the upgrade, you will find that the CPU usage by the Compiz process is prohibitively high, even if your entire system is idle. Utilization would be very high if you were using a large graphics application like Earth Navigator.

    I also had to turn off Parallels 3D acceleration to open the main toolbar as a working method and open almost all windows. It looks like there is an interaction that could be related to Parallels.

    Geek warning: you can skip this if you’re new to words like Linux, Ubuntu, Unity and Compiz πŸ™‚

    Note. Several readers have informed me that this advice did not help them. I have included this suggestion here because it seems to help in some cases, but is not intended to be used as a bulletproof mixture. Do your own research before taking any of the following steps. My sources serve as a starting point.

    I had a problem for a long time with my completely Ubuntu based computer where Compiz was consuming a brand new The amount of processor power, even when the computer was idle, even if the program was not running. My laptop is pretty powerful. So if Compiz is using 20% ​​of all processor cores, there is a lot of processing. This can cause the processor to heat up, causing the fans to run faster. It also makes noises that annoy me. Something had to happen.

    I stumbled upon a solution for the last point, and if it is difficult to find, I will take this opportunity to share it with the world again.

    1. If you have already installed compizconfig-settings-manager and run it. It is a great tool that allows you to change many of the hidden settings related to Compiz.
    2. Under General, click OpenGL:
    3. Disable “Sync with VBlank” and select “Fast” in the texture filter:

    The transformations take effect immediately, as you can see in this screenshot of your own processor monitor before, during, and therefore after this change:

    This is how it looksit the computer is idle after making the above changes without rebooting:

    I (want) to know the technical reasons for this problematic behavior or why this solution works. I’m just glad it works!

    The last update before April 14 resulted in a high utilization of the Compiz processor. When I run top I can see how it goes up when I hover over the dock. So if I give Sublime focus the path to Emacs or Gedit it will be 50% or more for you. As soon as I focus on the corpus again, it drops by a few%.

    ubuntu compiz cpu usage

    Hello everyone. I am running Ubuntu 12.04 on my laptop and just mine and my computer, I really like it. However, lately my system has been showing some strange routines. It seems like it really hesitates to work and from time to time it freezes when I play a CD (scratched for example). Online media also seem to quickly switch to random transfer mode. There may also be other issues such as logos not showing when I open working applications, etc. When I open the monitor, I find that Compiz is using over 100% of my CPU even without a window open. Couldn’t this be normal behavior? This has usually never been a problem in the past two or three weeks. I tweaked and reinstalled on 12/04 and the downside is still there. Has anyone had similar problems or know how to fix them? With Ubuntu Classic, the Compiz CPU gap is not as high as the average, but still 50%. I know xfce will probably solve this problem, but I applied for Unity and it’s really a lot of fun, poet I wish I didn’t want to change anything. Thank you

    Edit: I decided to uninstall the proprietary FGLRX driver for my graphics card and device and started using the new Ubuntu open source driver. For now, the situation seems to return if you need to get back to normal πŸ™‚ Thanks everyone for the input and advice!
