A dual head problem

Bonjour,

I have two monitors and an nvidia graphic card. I uses the nvidia
proprietary driver from rpmfusion and have configured the system to
use the twinview option.

I need to load an icc profile for each screen (they are not exactly
the same) and this seems to be impossible under this configuration....
Am I right?

So I changed my config: separate screens + xinerama
With this config, I can load one icc profile for each screen *but*
when I have to use a Qt window (Emacs, skype, rxvt....) the X server
crashes.....

I don't know what is reponsible: nvidia driver or Qt, but I do need to
use Emacs and some other application using Qt.

Is there a solution to my problem: load an icc profile for each screen?

I am under fedora 21 and uses xfce as window manager.

Thank you.
