Edit your /etc/X11/xorg.conf file the first part is the monitor section, make sure you have the right H V set for your monitor. First make a copy of your xorg.conf like so, as root open a terminal and log in as root su then give root passwd. Change into the X11 directory, like so (if you didn't know how) cd /etc/X11/ enter. Then make the copy with the command cp xorg.conf xorg.conf.old enter. That way if you mess things up you will have the original copy saved.


Code:
Section "Monitor"
        Identifier      "Generic Monitor"
        Option          "DPMS"
        HorizSync       30-83
        VertRefresh     56-75
EndSection

The next part to edit is the default modes section, ie if you are using a DefaultDepth 24 edit that section. The xorg.conf is read from left to right, so in this example 1024x768 will be the default setting.


Code:
 SubSection "Display"
                Depth           24
                Modes           "1024x768" "800x600" "640x480"
        EndSubSection

***many thanks Ranger, ive printed this and will try later. At moment got another problem !
the HD has windows + 3 diff Linux, and now GRUB has got messed up (dont ask!) giving error17.
ive repaired Mbr with Paragon and now in Win, so what i need is some Utility to re-Setup Grub.
maybe something i can keep on Floppy, for general probing installed Linuxes to set their boot
and Swap file locations. at moment, re-installing any one of them upsets the others.
thanks for any advice. its all a mystery to me.
i just keep throwing bricks at it till something happens

To configure your graphics card settings, you can also use system-config-display.
