Thanks for your suggestions, Tak. I am looking for screen-blanking without
starting X - because I have a number of these installations on Sun machines
which are set up as X-terminals, with users being able to select either
local display management or remote display management at login.  It works
fine with 'screenblank' on the Suns - and the users have 'xlockmore' or
a remote (CDE or OpenWindows) 'xlock' once they are logged in.

I am now setting up identical environments on some PC's. 'apmcd' looks
like it might be appropriate - but it gives the following message when
I try to start it.  So what else do I need to do?
  pmd: cannot open device file `/dev/apmctl': Device not configured
