xorg.conf and multihead

[Hubertus Hiden]

Hi Folks !

I'm running Hoary with a Matrox G450 with 2 different 15" LCD Screens.
If I turn off xinerama mode I can set the screen resolution an refresh
rate using Gnome's "Screen Resolution Tool" (Don't know the exact name
since im using german.)
The first screen needs 1024/768 at 75Hz and the second needs 1024/768 at 60Hz.
Now if I turn on xinerama mode and restart gdm everything works fine.
But after a reboot the second screen works with 75Hz instead of 60Hz.
Any hints would be great.

Thanks,
Hubertus
