If pressing the power key does not suspend your system, refer to the following procedure.
Verify that the key processing daemon is present by typing this command:
% ps -eaf | grep speckeysd |
If the resulting message does not list /usr/openwin/bin/speckeysd, you will need to start the key processing daemon.
Start the key processing daemon (if necessary) by becoming superuser and entering this command:
% /usr/openwin/bin/speckeysd |
