Appologies to all. The fix did not work. Using the "gdmsetup" does not stick. Changes are made but restart shows the settings revert. Going into the gdmsetup does not even work when using "activities >> set up GDM" in the gnome log in screen. "Force version" is not available in Synaptic. Short of re-installing and not updating, or living with the "Gnome PCLinuxos" log in screen, are there any other solutions?
