Compare your process listing (`ps aux`) from this 25% case with the high cpu case (if you can still reproduce the issue). Examine each process listed in the latter case but not the former.
*Usually* high X CPU is caused by some other X client process making too many requests of the X server. These cases aren't bugs in the X server but rather in the client application (perhaps it's stuck in some loop that makes excessive X calls). -- High Xorg CPU usage? https://bugs.launchpad.net/bugs/449196 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
