Oh, I know drivers can be an issue, that's why I tested with varying hardware. Also, service sub-subsystems can also be culprits as well, hence my preparedness to initially trust those assuring me to swap distros, which I dutifully did, only to be again disappointed by a lack of stability.
I think it speaks to how hardened KDE is or should I say, how KDE lacks fault-tolerance in that it seems so improbable that it can be implemented or rolled out in a way that provides a stable solution for a desktop environment.
At this point I should acknowledge that Gnome isn't absolutely perfect from a stability perspective, but it almost is. But more importantly, when compared to KDE, I've found Gnome to be leaps and bounds more stable. That may be because it's less ambitious as a platform, but I can live without ambitious and grandiose software if it's stable and reliable.
