Yes, by writing to frames I will lose basic window manager facilities such as
being able to reposition individual monitors. However, I must confess that I
don't understand why this should make a difference to my problem. Surely,
concurrent 'd.rast' processes will still be involved?

All maps are in the same region. I guess my main questions are whether I have
struck some limitation with GRASS, whether the problem is due to the use of
an outdated X driver, or whether our installation process is the culprit. Any
