I've never been a Lubuntu user but the problem I see is that the Linux distros supporting x86 are getting rarer it seems.
I have a 2004 nx7010 (awesome laptop, at the time and also 8 years later) that I sometimes use at home or grab to play around with and try out different distros and OSes. I used to use ArchLinux but they stopped supporting x86 a while ago. VoidLinux is also out. Right now I'm running OpenBSD 6.2 on it, which is nice - but the short release cycle for a machine you only start up like 3 times before the OS is EOLed kinda sucks. (Not OpenBSD's fault, of course.)
So we'll see how long one can get a decent Ubuntu fallback solution (as in, it's big enough that enough people work on it that it will mostly work out of the box for these hobby projects of running old but not ancient hardware) for x86.
Last time I was hanging out in the xubuntu dev irc channel I think there was some chat about how they were short on x86 hardware to test on. Emulation is useful but isn't enough, if you need x86 consider running tests or donating hardware.
See, that's the problem - it's not a real "need" - I have 2 old laptops I don't want to throw out. If I was donating them, my need would vanish ;)
Sorry if it sounded like complaining, it wasn't my intention. I just think x86 is dying a slow death, there are not many "enthusiasts" like for e.g. 1980s or 1990s hardware where you have "this one ancient build everyone uses", but x86 has no discernible advantage over x64 these days (please don't name the the RAM requirements for 32 bit builds now :P) - so x64 is in 99% of cases superior and that's why it's rightfully supported. e.g. VAX, Sun SGI and C64 stuff is exciting, x86 in the age of x64 is just "older and slower" to most people.
