Tried a couple of other kernels, but the problem remains. 3.4.50-030450-generic 3.8.0-25-lowlatency

For now, I just purged the adobe Flash plugin as it does not really provide critical functionality for me. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1189645 Title: General lag under desktop environments To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1189645/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
