Completely black screen after switch from XFCE to KDE Desktop - any advice?

I don't know about the current plasma, but in MX19, I did add KDE Standard to one of my MX XFCE installs. I can't recall exactly which, but either

- the Qt theming (all our MX tools are Qt and there is a built in setting that makes Qt apps follow the gtk2 theming in the enabled gtk theme) in XFCE was messed up by Plasma's theme settings,

- or the gtk theming in XFCE was messed up by the Plasma settings for theming Gtk apps.

- Or maybe it was the settings in XFCE that messed up the themeing of gtk apps in Plasma.

So I never bothered to repeat this experiment of adding Plasma to a default XFCE install. Plus in the years since, Plasma desktop has gotten more systemd-reliant without the "mx-modified" stuff that dolphin adds [TO CLARIFY - I have MX-KDE installs, but I didn't know if installing the KDE metapackage onto MX XFCE would cause issues nowadays because of missing sysvinit fixes, etc].

On the other hand, I have found it quite doable to have gtk-based DE co-exist. =

XFCE + LXDE [Manjaro install #1)
XFCE + Budgie [Manjaro install #2).

Both started as pure XFCE installs.

I have also just installed Cosmic desktop [which is not Gtk but Rust-based] onto an Arch+Gnome install, and so far it's fine, because Cosmic even in its alpha state does a pretty good job of making gtk apps follow its own theming. Not so much Qt apps, so I theme the Qt apps I use with Kvantum.

Thanks for the heads-up @asqwerth . KDE installation worked fine for Adrian and me when testing for the video early this year, so I would not have been much help to this enterprising OP and really appreciate your stepping in.

Its a little tricky to package KDE and fluxbox together, at least in current forms. the way they set gtk settings actually conflict with each other to an extent. (actually, fluxbox doesn't set gtk settings, but you know what I mean). the usual effect is that KDE will override colors in a chosen gtk theme on non-KDE desktops.

but not impossible.

Too bad, thanks.

Maybe we entertain the idea of a couple of natural pairs instead: Xfce + Fluxbox, KDE + Lxqt ...

KDE + Lxqt would be nice. I used the latter some years ago on Fedora and quite liked it. Some say it's the poor man's KDE but so what...
