Just wondering whether you considered netbooks here. Not that old (maybe 6y?)
and at least the two specimens I would have around are early Atoms (i386 only)
but with (also early) i915 Intel graphics. They used to be reasonably
accelerated to cope. Not sure about unity 7. But maybe some reason to allow at
least for 16.04 some i386 iso (by 18.04 the problem might be resolved through
the crappy life-span recent hw seems to have)...
