My point was really that he shouldn't try to upgrade his entire
distribution at all, at least not until it is determined that an
upgrade would be the only way to solve his problem. In this particular
case it might be possible that an update actually broke something - we
don't know yet.

If he were to do an upgrade, he should make a backup of _everything_
before doing so, especially as he needs his machine in working order or
Monday. And he should probably stick to upgrading to trusty, unless he
really needs vivid.

Another thing he could have done would be to boot from for example a
trusty live image to see if that works better at all before
contemplating an upgrade.

In short, as he needs his machine on Monday he should be quite careful
with things he does to fix it right now. Your advice could have gotten
him into a situation he would have a hard time getting out of, and that
is what I objected to.
