Start screen after su’ing to another user

Today’s problem is one that requires no introduction (well, maybe it does :-| ) but it’s a problem nonetheless.  The issue is that after using the ‘su‘ command to become another user, there’s trouble running screen sessions.

This page (http://dbadump.blogspot.com/2009/04/start-screen-after-sudo-su-to-another.html) details it simply and perfectly (which, yes, I know in turn came from another page).  Essentially the error is thus:

Cannot open your terminal '/dev/pts/1' - please check.

Which really doesn’t man nor beast with its descriptiveness.  From that page, which came from another page mentioned on that page (?), here’s the fix:

su [userName]
script /dev/null
screen -x [screenName]

And that’s it!  Simple solution, and many thanks to that blog for sorting it out for me.
