Yes you are right, it should work.  However my experience with an old
machine that ran Unity 2d fine was that s/w rendering was effectively
unusable as it was so slow.  I will have to try again however as it is
some months since I last gave it a go.  I suspect it will still be so
slow that something like Lubuntu is much better.
