I hit this and manage to get myself out of it.

I run with many xterm windows open. After opening the lid in my Inspiron 6000, I switched to a workspace with an open xterm window and type the equivalent of:
xset dpms force suspend

(I usually use this command to blank the screen "right now".)

$ more ~/bin/blank
#! /bin/sh
sleep 2
xset dpms force suspend

Then when I move the mouse pointer or press a key, the screen turns back on.
