The high X cpu usage is probably just a symptom, not an indication of a bug in X itself.
X is a server and responds to requests from client applications. If the client app is broken, it might make X requests too rapidly, which bogs down the X server (well, at least it doesn't crash!) In such cases the bug is really in the client application. For assistance in troubleshooting issues with high CPU loads for X, see this troubleshooting guide: http://wiki.ubuntu.com/X/Troubleshooting/HighCPU ** Package changed: xorg (Ubuntu) => ubuntu -- xorg 100%CPU when I watch video on youtube https://bugs.launchpad.net/bugs/436496 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
