Re: Getting point-and-click working

[Andrew Bernard]

Hello All,

Didn't this come up in 2015 on the list here:

https://lists.gnu.org/archive/html/lilypond-user/2015-06/msg00168.html

Is it that the Ubuntu lilypond is broken (still)?

FWIW though, on my pristine Ubuntu 18.10, clicking the PDF just does nothing. nada. All works great on Debian 9.

Ok, this might depend on the editor you use.
I remember Gedit opened twice before that fix.

In case you have troubles with other editors, you can safely delete "-e
main" in the exec line in lilypond-wrapper.guile.

0 is the root user id. 1000 is your user id.
ouid is the object owner id and it's assigned to the root user. No idea
what is the object  here... if it's the executable, then it's correct.

You should not change the ownership of the scripts in /usr/local/bin.

You might search for other files owned by root in your home directory,
e.g.:

$ find ~/.local -user root
$ find ~/.config -user root
