In terminal use 'top', looks PID of 'backend' (ctrl + c, to ends top) and type 'sudo kill -9 (PID of backend)' In my case, it was 'sudo kill -9 3533' This problem starts when, for curiously, I run the application 'System Testing'... and close without do anything. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/556636 Title: Program backend consumes more than 90% CPU after System Testing To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/checkbox/+bug/556636/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
