 If someone could take a look at http://bugs.debian.org/428797, I'd
 be grateful. Jamie says that:
 
  2: xscreensaver already receives and reacts to RANDR
 RRScreenChangeNotify events (in driver/timers.c:1010);
 
 yet, I can reproduce the problem: after adding new screen estate
 with xrandr, XScreensaver does *not* blank it when it locks the
 screen. If I restart the daemon, then it works appropriately.

I suspect the method described in the above item 2 predates RandR 1.2
and is no longer adequate. The method described by Keith Packard above
or something similar needs to be used now.

For your convenience, driver/timers.c is available here:

  
http://scratch.madduck.net/__tmp__cdt.Tke15337__xscreensaver-5.03__driver__timers.c

I have a setup here in which I can try things out, but I don't have
the time to dig through the code.
