What graphics card/chipset do you have (give the output of lspci if you 
are not sure). You could try creating an xorg.conf file 
(/etc/X11/xorg.conf), and specifying graphics settings there manually. 
You can find more information on this in the manual page (man xorg.conf).

This is of course an example, and a configuration file for your graphics 
card is probably very different. Hope this may be of some help.
