So for a 1280x1024 monitor edit /etc/xorg.conf and change ...

Section "Screen"
        Identifier      "Default Screen"
        Monitor         "Configured Monitor"
EndSection

to ...

Section "Screen"
        Identifier      "Default Screen"
        Monitor         "Configured Monitor"
        SubSection "Display"
                Virtual         1280 1024
        EndSubSection
EndSection

I differ from this solution, I found following config:

Section "Monitor"
Identifier "Monitor0"
Option "PreferredMode" "1400x1050"
Option "DPMS"
EndSection
.
.
.
Section "Screen"
Identifier "Screen0"
Device "Card0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Modes "1400x1050" "1280x1024" "1280x960" "1152x864" "1024x768" "800x600"
EndSubSection
EndSection


The PreferredMode and Modes is the key.
