I've already posted a copy of my xorg.conf file.
I've since discovered that the display works fine if I login using a
standard user account. The problem with the right monitor only occurs if I
login as root. (I've been logging in as root while setting up the box.)
When logged in as root, the screensaver daemon won't start unless I first
type "xhost +localhost", and as soon as I try to start the screensaver, the
right monitor display "turns on". The screen lock doesn't work either.
(All of this works fine if I'm logged in as a user.)
