It appears that Archlinux has moved to Xpdf version 4, whereas Debian
uses version 3. I don't know why urlCommand has been removed, but
maybe the Arch lists/forums/wiki might help. Nor do I know how or
whether LP's textedit URL's would be workable with "launch"-type
links mentioned in that forum and in xpdf's documentation.

Then it sounds as if XFCE's browser honours LP's URLs. I read that
exo-open is specific to XFCE, so you'd presumably configure that
one, and leave the other unconfigured. OTOH if you can't find
exo-open's documentation, then at least LP documents xdg-open in
the Usage manual.

I don't remember the outcome in the atom discussion (concerning the
line/column arguments). You can study the invocations about 90% through
lilypond/usr/share/lilypond/current/scm/editor.scm (substitute your
path elements). But the problem seems to be morphing.

Sorry, I can't keep up. The last iteration of my experience is given in
these posts. Their references and follow-ups have other experiences that
might differ from mine, and even be more applicable to your case(s).
Just pick and choose what information you need.

And there was also a thread in March 2019, which IIRC concerned itself
mainly with the interaction of point-and-click with apparmor.

Cheers,
