Not to mention, even if it IS supported, it may not be for long.
I have a small 11.6" laptop, that ORIGINALLY SHIPPED WITH LINUX UBUNTU. I bought it off of Newegg some years back.
Well, you know the "patch early, patch often" mantra often repeated around here, about keeping code up-to-date, to receive continued support, and to prevent exploits and malware.
So, it shipped with Ubuntu 12.04 LTS. I upgraded it to 14.x.x LTS. Then, after I do updates, it won't boot, unless I manually boot in compatibility mode. Something wrong with the Ivy Bridge Celeron iGPU driver or x-server.
I mean, it's freaking Intel standard hardware, although it's a few years old. You would think that they wouldn't drop support for something like that, but there you have it. No support, any longer.
Have to stay on Ubuntu 12.04 LTS.
Edit: To elaborate, I had once upgraded it to Ubuntu 14.x.x LTS successfully. But when I did it the last time, as part of the distro upgrade, it downloads and installs the "latest" kernel in the series that that Ubuntu version used. Which, coincidentally, dropped support for Ivy Bridge Celeron graphics. Or it's just horribly busted (in that kernel), one of the two.
