Screen lock stays blank.

[David Pfeffer]

I have 11.10 running on an HP Mini. When "Lock Screen" is selected in the menu, or CTRL+Alt+L are pressed, the screen locks and resumes normally. However, when the screen turns off after the selected time interval (i.e. 10 minutes), it will not turn back on. This occurs both when the lock feature is turned on and off.
