I can always tell when my screen is blanked because my CPU fan is roaring. I on an HP elitebook with Radeon HD 6470M graphics and am running the fglrx driver.
I found that it takes about a minute for the CPU to start spiking after the screen blanks. From running top, compiz goes from 0 (for about the first 20 seconds) to 30 to 100. I ran your script in a loop every 5 seconds, there are approx 26 runs in that file The last stack in there may show it starting to wake-up as I bumped the mouse during the last trace. If I can gather more info, please let me know. ** Attachment added: "compizstack_mfisch.txt" https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/969860/+attachment/3069087/+files/compizstack_mfisch.txt -- 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 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
