+@unnumberedsubsubsec Using GNOME 3
+
+In GNOME 3, URIs are handled by the @q{gvfs} layer rather than by
+@q{gconf}. Create a file in a local directory such as @file{/tmp}
+that is called @file{lilypond-invoke-editor.desktop} and has the
+contents;
+
+@example
+[Desktop Entry]
+Version=1.0
+Name=lilypond-invoke-editor
+GenericName=Textedit URI handler
+Comment=URI handler for textedit:
+Exec=lilypond-invoke-editor %u
+Terminal=false
+Type=Application
+MimeType=x-scheme-handler/textedit;
+Categories=Editor
+NoDisplay=true
+@end example
+and then execute the commands
+@example
+xdg-desktop-menu install ./lilypond-invoke-editor.desktop
+xdg-mime default lilypond-invoke-editor.desktop x-scheme-handler/textedit
+@end example
+
+After that invocation;
+
+@example
+gnome-open textedit:///etc/issue:1:0:0
+@end example
+@noindent
+should call @file{lilypond-invoke-editor} for opening files.

+@node Extra configuration for Evince
+@unnumberedsubsubsec Extra configuration for Evince
+
+@cindex Evince
+
+If @code{gnome-open} works, but Evince still refuses to open point
+and click links due to denied permissions, you might need to
+change the Apparmor profile of Evince which controls the kind of
+actions Evince is allowed to perform.
+
+For Ubuntu, the process is to edit the file
+@file{/etc/apparmor.d/local/usr.bin.evince} and append the
+following lines:
+
+@example
+# For Textedit links
+/usr/local/bin/lilypond-invoke-editor Cx -> sanitized_helper,
+@end example
+@noindent
+
+After adding these lines, call
+
+@example
+sudo apparmor_parser -r -T -W /etc/apparmor.d/usr.bin.evince
+@end example
+
+@noindent
+Now Evince should be able to open point and click links. It is
+likely that similar configurations will work for other viewers.
