Can I use the nouveau driver in xorg.conf to Lock in the resolution ?.

I have a computer that defaults to 1920x1080 and that resolution is to 
high, and I have a older friend that will be using this computer and I 
want to Lock into
1280x1024x75 .

I don't want to use the nvidia drivers they are to unstable and nouveau 
drivers
are doing a good job on this computer.
Try adding something like the following to your /etc/X11/xorg.conf file, where 
the "Identifier" is what you get from `xrandr -q`.

Section "Monitor"
        Identifier   "DVI-I-1"
        Option       "PreferredMode" "1280x1024"
EndSection

Section "Device"
        Identifier  "Device0"
        Driver      "nouveau"
EndSection

Thanks for the initial Info.

After I got it working  I found this a Fedoraproject.

This did the job:
