Hi Harry,

It would benefit us to learn the contents of your xerrors, as I suspect
this would give an indication as to what went wrong.

You can also drop to a TTY (not sure how to do this in VBox since I use
virt-manager) and then log in there.  Once logged in you can copy your:

~/.xsession-errors

and

~/.xsession-errors.old

you can also check dmesg and look at systemd logs via journalctl

You can use journalctl for kernel logs also alternatively by using the
--dmesg option

I think by looking at the xsession errors it might give a clue what
happened.


Did you install any software on top of the vanilla Lubuntu install?
