Christopher, thanks for the guidance. Yes, the problem does not appear in Trusty from a Live USB.

The kernel is Linux ubuntu 3.11.0-12-generic. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1270980 Title: [Lenovo ThinkPad X230T] suspend in dock, undock, then resume screen doesn't respond to keyboard To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1270980/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
