Indeed. Compiz isn't drawing the screen to show the result of polling for load so its essentially sleeping during this time > > -- > You received this bug notification because you are a member of Unity > Bugs, which is subscribed to unity in Ubuntu. > https://bugs.launchpad.net/bugs/803943 > > Title: > compiz consuming a lot of cpu > > Status in Unity: > Confirmed > Status in “unity” package in Ubuntu: > Confirmed > > Bug description: > This problem is exclusive to unity (when running compiz with gnome- > panel, this doesn't happen). > > 1.

Notice that compiz consume much more CPU than idle (about 25% in my case), although I'm not doing anything related to window management. > 8. (optional) Install the gnome-panel package and choose "GNOME classic" in login screen. Start compiz with "compiz --replace" and follow the steps from 1 to 7. Notice that the CPU consuming is much lower (in my case, 1% when idle, 25% when moving the window and 9% with the video). > > ProblemType: Bug > DistroRelease: Ubuntu 11.10 > Package: unity 4.0.1-0ubuntu2 [modified: usr/bin/unity-preferences usr/share/applications/unity-preferences.desktop] > ProcVersionSignature: Ubuntu 3.0-2.3-generic 3.0.0-rc4 > Uname: Linux 3.0-2-generic i686 > Architecture: i386 > CompizPlugins: [core,bailer,detection,composite,opengl,compiztoolbox,decor,vpswitch,imgpng,resize,snap,grid,regex,move,gnomecompat,mousepoll,animation,unitydialog,wall,workarounds,place,expo,ezoom,session,staticswitcher,fade,scale] > Date: Thu Jun 30 11:54:20 2011 > InstallationMedia: Ubuntu 11.10 "Oneiric Ocelot" - Alpha i386 (20110610) > ProcEnviron: > LANGUAGE=pt_BR:en > LANG=pt_BR.UTF-8 > SHELL=/bin/bash > SourcePackage: unity > UpgradeStatus: No upgrade log present (probably fresh install) > > To manage notifications about this bug go to: > https://bugs.launchpad.net/unity/+bug/803943/+subscriptions -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/803943 Title: compiz consuming a lot of cpu To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/803943/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
