[opensuse] Keyboard Randomly Stops Working (sort of)

I am using openSUSE 11.0 64-bit and at random times the keyboard stops working to input text, but if I press ctrl+alt+backspace I hear a beep and if I press it again the X server restarts and I am back at the login screen and the keyboard fully works again. What can be causing this? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
