[CentOS] X, why did it have to be X

I have one user. We've pretty much all got two monitors, but he insists on
rotating both of them vertically - that is, they're taller than they are
wide, and he's got a Radeon card. I always have X grief on his system when
I update it....

I just did a full update. X comes up in both screens... but the left one
is *not* rotated, while the right one is. And they're mirrored. I've
logged in as root, looked at all the configuration I know of, and nothing
tells it to mirror, or one rotate and the other not. But when I use the
menu, and go to system->preferences-display, it shows mirror screens
*always* checked. I uncheck that, and hit apply, and nothing happens. I
move the one off from over the other, and rotate the other, and still,
nothing at all happens, and I don't see anything written, anywhere.
