Ok so many things:
fist the conf of my computer:
Athon 2800
256M
Opensuse 10.1 i 586
nividia geforce mx4 4000

In my "module" is type this:

Section "module"
   Load       freetype
   Load       type1
   Load       dbe
   Load       glx
   Load       extmod
   Load       v4l
EndSection

and the other (Device):


Section "Device"
  BoardName    "GeForce4 MX 420"
  BusID        "1:0:0"
  Driver       "nvidia"
  Identifier   "Device[0]"
  VendorName   "NVidia"
EndSection

the resolution i like is 1152x864_75hz!

 
So we i change the xorg.conf the module to just "glx" and "other module" the screen go to shell. And i have to run the sax2 and everthing back to normal!
so someone have any solution!

Be health
