I have the same problem. After a while keyboard gets unresponsive. A workaround seems to be to unload and reload the usb module: sudo modprobe -r uhci_hci;sudo modprobe uhci_hci
After that keyboard seems to work normally for a while. -- spurious keyboard events https://launchpad.net/bugs/63024 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
