Good. Just checking :-)

Good - you didn't edit the passwd and group files directly, always a
source of errors and strange symptoms.

Well, the GUI is asking for the wrong password, and gksudo is a
graphical sudo, so...

If your username was "thisismyusername" and his was "thisismyusername1"
then there may have been username length issues. Also, if you had chosen
to call yourself "adm" or call him "gdm", I would foresee problems,
though admittedly not these ones :-)

You could try checking log files, and looking at process ownerships,
might find a clue there.
