So, here's the solution:
Even if you plug two monitors into your videocard, you still make two sections
'Device' with the same BusID for your videocard.
Notice that I put 'screen 0' in the first device and 'screen 1' in the second.
In an example I saw this thing in the 'ServerLayout' section, but that didn't
work for me.
Also notice that I disabled the 'option "MonitorLayout"': When I enable this
one, the whole thing doesn't work.
In the section 'serverlayout', two screens are defined, one default, and one
with external screen. Notice that the first one is the default screen and not
the external, otherwise it doesn't work either. (sensitive isn't it ?;-)
Then, for the xinerama mode, include a section 'serverflags' where the option
'xinerama' is set to 'true'.
That's for the XF86config.
With all this configured, the 'multiple monitors' option is now visible in:
control center -> peripherals -> display
attached: My XF86Config file.
Good luck.
