I have a similar problem. In previous Fedoras it was possible to select
the monitor to be used during booting or display the booting screen in
both monitors.
It looks that the distro is becoming less flexible or much harder to configure.

Hello,
I have had a video display issue after an update a few months ago. I
cannot post from work due to mail filters so I am posting from another
account so responses will be slower.
Fedora 18, 64bit, clean install using nvidia graphics with Nouveau using
KDE. Both monitors are the same make and model. Purchased at the same
time.
Before the problem occurred, I would boot and get all messages on the
left screen until the X server started. If the screen saver locked the
screen, the unlock dialog box would be on the left screen (screen 0). I
could run KDE with effects enabled. The first indication of a problem
was the reboot after the kernel upgrade and error messages about the KDE
desktop effects not being able to run.
Due to work schedule, I couldn't deal with the problem before now.
Now, when I boot, the left display shows the BIOS boot and then the
displays enter mirror mode. When the X server kicks in and KDE starts,
the display goes to side by side as expected. The desktop works as side
by side when I can drag windows between the monitors and virtual
desktops as expected, just slower.
I cannot run any of the KDE desktop effects.
When the screen saver kicks in, it is a different screen savers on
each monitor, not one across both. Previously it was one screen saver
across both monitors. Using the Galaxy screen saver, the star movements
would go between the screens. Now there are two different galaxy scenes
and motions.
If I move the trackball, I get a unlock dialog box on both screens but
they are not mirrored. If I enter a password in to either dialog box,
the desktop unlocks.
I cannot use anything that requires a full screen such as You Tube
videos in a browser or any game.
I have gone through the settings in Grub and tried different desktop
settings. Nothing I can find on the net has pointed me in the right
direction on this matter.
This setup has worked flawlessly for two years now and worked well until
the update.
Due to this issue, the system runs slower when moving between screens or
virtual desktops. Lack of full screen is a pain for some things. No
Tux Extreme racer unless I want mirrored action.
I have tried changing the "GRUB_GFXMODE=" with no success.

I hope someone can point me in the right direction to get operation back
to normal.
