Using an APL keyboard under X11 KDE 6

At least the APL keyboard I use can generate up to five glyphs on a given key, the usual unshifted and shifted, but also ralt-unshifted for some APL functions, ralt-shift for other functions, and ralt-ctrl for yet other functions. This used to work under an older X11 KDE Plasma but now the ralt-ctrl doesn’t work. Pressing ralt-ctrl-k, for example, used to produce a quote-quad. Now, nothing happens.

All of this seems to involve something called “level 5” in the X11 kbd stuff and research is suggesting that KDE is somehow involved. Does anyone have a clue about this? The net says things about specifically enabling level 5, but I can’t find anything about that.

Thanks

Please copy your config at ~/.config/kxkbrc, so that we know your exact keyboard setup.

Also: what is the version of the xkeyboard-config/xkb-data package?

Thanks for the response.

The problem was that it used to be that ralt had to be pressed and held, then rctlr pressed and held, and then the appropriate key. For reasons I don’t know and discovered only by accident, the order now has to be rctlr-ralt-key, i.e., the necessary order of the modifier keys has been reversed. (The older behaviour was under Fedora while the new behaviour is under kubuntu. That might have something to do with it.)
