That helps. Here we go...

[[KM400]Haven't been able to execute normal gnome login since 10.04
installation; screen blanks then returns to login screen]

After a fresh 10.04 installation which seemed to go perfectly, I now
can't execute a normal gnome login, but can using safe mode gnome and
xterm. When attempting a normal login there is a short wait after the
login screen disappears, then the screen goes blank for a few seconds
before returning to the login screen.

Perhaps try the workaround in comment #3:
There was no existing xorg.conf file in /etc/X11, so I
created one with the following content;

    Option "AIGLX"


You can do that from the recovery mode; boot to recovery, continue to
login, and from the console:

$ sudo nano /etc/X11/xorg.conf
and then add the above, ctrl-x to exit & save.

If that's not it, have a look through some of the other bugs for that
and see if you can spot one that better matches your situation.
