Mon 28 Jan 2013 03:47:50 PM UTC, comment #4: The two keyboards (actually a keyboard and number pad) are definitely not the problem. Unplugging the keypad generally does not help. Unplugging the Wacom device has a 100% success rate. In fact, it's the only device that has any effect on this problem. |

The Windows 8 one does not seem to have this problem. In the OP I mentioned that there was no problem with Windows (then 7) or the old GRUB. I only have this problem in GRUB2.
