Did you hot tighten the nozzle while putting it back? Don’t think it caused your current failure, but cold tightening can lead to more clogs in the future.
I think layer shifts can be caused by many different things, but the first thing I’d check is that the bed carriage can move freely and there isn’t something mechanically blocking it, like a wire or a misplaced screwdriver. The second thing I’d check would be the belt and gears, so that the bed can’t move without the stepper motor also spinning.
If you want a DE which looks similar to KDE, try Xfce with Arc theme and some nice icon pack.
I use KDE (and it’s snappy on my hardware) but I like it because it has a lot of features and advanced options which it tries to make easily accessible to the user. IMO this is pretty much the opposite of “modern”, which is usually very minimalist, and UX designers like to remove or hide as much as possible. I’ve tried Gnome several times but personally I can’t stand it just because it’s a modern UI :) You try as many as you can and pick the one that suits you best of course, just thought it was funny that the same word can have different meanings to people.
