Compiz makes CPU run at 100% when in suspend mode in 12.04

12.04 compiz suspend cpu-load

Solution 1

What video card do you have? What driver are you using?

There's a number of bugs that a Google search turns up.

For the 2nd one, a possible solution is to disable the file watcher plugin in ccsm. However, this plugin is not enabled by default, so that solution may not apply.

For the 3rd one, a suggested workaround is to enable either the "Force full screen redraw" or "Vertical synchronization" options in ccsm.

Do any of those bugs seem related?

Solution 2

Had the same problem on HP Pavilion dv6 with ATI Radeon HD5000 series card. It does seem to be the same as this.

The solution for me was as stated above to "Force full screen redraw" via ccsm and to follow the steps in the workaround 1 on the bug report itself.

Solution 3

I have the same issues with cpu usage because of compiz. My workaround was to switch session from Ubuntu to Ubuntu 2D.

ubuntu 2d

Recently I installed Ubuntu 12.04 on my laptop. And I found that when I left my laptop suspend mode, the Compiz hold CPU at 100% all the time until the laptop woke up.

Can anyone tell me what is happening?

  Hi, and welcome to AskUbuntu. The question is somewhat vague. Can you explain how you checked CPU usage when the computer has been suspended.

  hi, mike.At first I just notice the sound that CPU worked too busy when suspend.Then I started a "top" command and waited for the notebook go into suspend and I find the "compiz" process hold CPU 100% all the time.Apologize for my pool English.:)
