Here's a solution :
I add an other screen section in xorg.conf

Section "Screen"
       Identifier      "Screen2"
       Device          "Matrox Graphics, Inc. MGA G550 AGP"
       Monitor         "Monitor"
       SubSection "Display"
               Depth           24
               Modes           "1920x1440" "1280x1024" "1024x768" 
"800x600" "640x480
And I do :
startx -- :1 -screen Screen2
An It's OK
