Really, no one else has this problem. FWIW, it's not a hardware problem. If I run:
sudo sh -c 'vbetool dpms off; read ans; vbetool dpms on'
Then the screen turns off and then turns back on when I hit enter. (See http://askubuntu.com/questions/62858/turn-off-monitor-using-command-line ) So, there must be a problem in some higher level piece of software .
