“Admittedly, my Ubuntu sighting was a modest one: it involved
just one kiosk in my hotel, the Newhotel Select, which was offered
to guests for general-purpose computing. But there was no doubt
that it was Ubuntu. ..Unfortunately, since I didn’t notice the machine until I was
already late to catch my train out of the city, I didn’t get a
chance to figure out which version of Ubuntu it was running. But it
was most likely earlier than 11.10, since that release uses LightDM
rather than gdm, shown in the picture.
