Re-install the ATI/AMD driver. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1052090 Title: Unity dash extremely slow when attached second monitor To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/1052090/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
