Haven't really touched Mint myself, other than moving my dad's computer to it. I don't think it shows the user or device name over by the clock. Unless that XP skin adds it, I don't think that's it.

Given the "Overcast" bit, maybe it shows a zip code for the weather or something?

Again, I'm not settled on a particular distro yet for sure, but most of my experience is with PopOS so far, and there's nothing identifying there, so I'm not positive.

I've installed Mint on 2 family member PCs, but I haven't used it myself other than in passing.
