Thanks so much for the suggestions!
I ran (as myself) QT-DEBUG, and the same thing happened. Blank screen, but lyx
was showing in the bottom fluxbox menu bar, so I quickly closed the app and
managed to avoid the crash, and thus was able to copy the terminal output. It
was as follows. Sorry, its very long. It means nothing to me. I'm a long
time Debian user, but no sort of serious programming background.
I'll have a go with some of the other suggestions next. I guess one obvious
one is to install KDE andtry it with that, since someone reports having no
problems with that on Debian 12. Can always take it out afterwards. Or maybe
beta 2.4.
