I've installed Lilypond using the "Software Manager". This software generates a music sheet in PDF from a plain text file containing its description in a proprietary language. I was expecting that double clicking on a source file like say my_file.ly would automatically generate my_file.pdf in the same folder, much like the Windows version (port) does.
However, I get this instead:
Show other applications produces this list (no "Lilipond", "GNU Lilypond", etc. there):
Find applications online produces an error in two steps:
Somehow, the file type (MIME type?) is identified correctly (Lilypond music sheet, see 3rd pic), but I suppose maybe "Nautilus" is unaware that Lilypond is actually installed on my machine.
Indeed the application doesn't show on the list above, and also I've noticed it doesn't show on "Menu" -> "All Applications":
It does show as correctly installed on the "Software Manager", though.
I'm using Mint's Cinammon variant, which I'm extremely impressed with so far.
Thanks in advance for your help.
