I have the same problem. Today I've updated from 8.10 to 9.04 and I experience high CPU usage by XOrg process (issues that with 8.10 I didn't had). Youtube HD videos don't work (when I click on HD the video doesn't show for some time, then when it does I have video tear and un-sync audio). The normal videos work but still high CPU (XOrg uses about 60% CPU). I tried using UXA but it was worse than EXA+greedy.
The computer is a Acer Aspire 5315 laptop. lspci: 00:02.1 Display controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 03) Let me know if I can provide more info. -- [i965] xserver 1.6.0 - High %CPU/Power Usage with Intel GM965 https://bugs.launchpad.net/bugs/364359 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
