Debian 12 and Lyx 2.3.7-1

[Eckhard Höffner]

I have no problems on debian, but I'm using kde. Starting from the 
terminal gives no output.

It appears that lyx does not connect to the windowmanager fluxbox.

I was going to post the slew of error messages from the terminal, but as soon as I opened Claws the display became unusable.  Moving the cursor led to a broad black line across the display, and clicking no longer worked.
