Have just found an article on Ask Ubuntu http://askubuntu.com/questions/337049/how-can-i-install-a-synaptics-pointing-driver regarding what should appear in the file /var/log/Xorg.0.log. Having checked the log file I found the following showing why the Synaptic driver is not being loaded. Investigating further.
