After filing comment #7, I rebooted the compaq system. As I was awaiting the system to complete booting, after the Grub2 screen closed - I was alternately hitting Alt F1 and Alt F2 and possibly Enter - somethow this time the lightdm login greeter appeared and I was able to log in. I'll attach the lightdm.log ...
