Four months in, and for some unknown reason, my Minisforum UM250 running Kubuntu decided to go all graphical-glitchy on me, as it had previously done in Manjaro and Arch. It then seemed to get better after a while, before going all wonky once more. Currently, it's in an 'OK' phase, but who knows how long that will last! I assume some software got updated somewhere along the line -maybe a driver of some sort- and this introduced instabilities where there were none before. But, frankly, at this point I don't care any more: the Minisforum is destined to be retired from desktop duties and instead will be translated to the loft, where it can run something 'server-like' that doesn't require a GUI nor day-to-day interaction with it. I haven't thought what, precisely, it might end up doing, but I'm sure I'll think of something before too long!
It's a shame (not least, because it wasn't cheap!), but I can't be having my daily driver desktop doing random things at random times. [...]
