can u post you xorg.conf? at least monitor, screen, and device (with your video adapter) sections.
I tried your suggestions Chris, still no joy. Here is my current xorg.conf. (I have also tried this conf with the added Option "IgnoreEDID" "1"). Thanks for your time on this everyone.

# RgbPath is the location of the RGB database. Note, this is the name of the
# file minus the extension (like ".txt" or ".db"). There is normally
# no need to change the default.
# Multiple FontPath entries are allowed (they are concatenated together)
# By default, Red Hat 6.0 and later now use a font server independent of
# the X server to render fonts.

# Specify which keyboard LEDs can be user-controlled (eg, with xset(1)) # Option "Xleds" "1 2 3" # To disable the XKEYBOARD extension, uncomment XkbDisable. # Option "XkbDisable" # To customise the XKB settings to suit your keyboard, modify the # lines below (which are the defaults). For example, for a non-U.S. # keyboard, you will probably want to use: # Option "XkbModel" "pc102" # If you have a US Microsoft Natural keyboard, you can use: # Option "XkbModel" "microsoft" # # Then to change the language, change the Layout setting. # For example, a german layout can be obtained with: # Option "XkbLayout" "de" # or: # Option "XkbLayout" "de" # Option "XkbVariant" "nodeadkeys" # # If you'd like to switch the positions of your capslock and # control keys, use: # Option "XkbOptions" "ctrl:swapcaps" # Or if you just want both to be control, use: # Option "XkbOptions" "ctrl:nocaps" # Identifier "Keyboard0" Driver "kbd" Option "XkbModel" "pc105" Option "XkbLayout" "gb" EndSection
