Monitor ghosting with Matrox G400 Dual Head Problem
 

I posted early trying to get my dual head g400 to work properly on both monitors. I resolved the issue of getting to video on both monitors. However, I have a new problem. On one of the monitors, I get a ghost image of the second monitor. The problem is isolated to one video, I switched the cables and the problem moved to the other monitor. I have tried various mga driver from the Matrox site and nothing has changed. Is there a way to fix this? Any suggestions????

I tried to post me Xorg.0.log here, but got a message that my message was too long. Let me know and I will repot it if necessary.

i posted a previous post asking if anyone had any warnings about
upgrading to fc2.
after many naysayers warned me against it, i finally upgraded with a
clean install.
to my chagrin, copying my old xfree86config to xconf.org did not work.

i see there have been several other posts asking how to do this so i am
going to post how i did it.

step 1: i did a clean install, letting fedora set up my xorg.conf file.
i am using a matrox g450 with two dell flat panel monitors. right out
of the box, they were both enabled in "clone" mode.

step 2: i just used the advanced tab under preferences: screensaver to
enable display power management. i set power management enabled. standy
after 15 min, suspend after 15 min, and off after 15 minutes. this
automatically enabled the power features. i did not have to add any
lines the x configuration file as in previous versions of redhat.

step 3: become root and edit /etc/X11/xorg.conf
after the section entitled
Section "Module"
blah
EndSection
I inserted these lines:

Section "ServerFlags"
Option "Xinerama"
EndSection

I saved and pressed control-alt-backspace to restart the xserver.
after loggin in again, i went to system settings: display.

there appeared a tab labeled "dual head" i clicked "use dual head"
then i configured my second monitor and picked spanning desktops.

after hitting ok, i hit ctrl-alt-backspace again and presto!!!!!!
xineraman was enabled with power management.
i did not install any of the matrox drivers or use the mgapdesk
utility. i just used the above instructions and that was it right out
of the box....

also as to everyone badmouthing fedora core 2 , i am very impressed and
have found a great many features that have been improved and generally
well thought out. i am very glad i upgraded....

if anyone wants to see my xorg.conf file here it is:
