Same problem HP dm1z-4100 (amd e-450) Setting "Force full screen redraw (buffer swap) on repaint" seems to improve performance overall, compiz normally uses 60-80% cpu when moving a window (crazy right?) and when set "Force full screen redraw (buffer swap) on repaint" it uses only ~30%.
Also the cpu usage is near zero % when the screen is off with the "Force full screen redraw (buffer swap) on repaint" option. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/969860 Title: [fglrx] compiz uses 100% CPU when screen turns off (spinning in glXWaitVideoSyncSGI or glXSwapBuffers) To manage notifications about this bug go to: https://bugs.launchpad.net/compiz-core/+bug/969860/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
