A patch working similar to the tty fallback would be okay. Something like this: --8<---------------cut here---------------start------------->8--- diff --git a/gnome3/pinentry-gnome3.c b/gnome3/pinentry-gnome3.c index d6d7d16..e79e852 100644 --- a/gnome3/pinentry-gnome3.c +++ b/gnome3/pinentry-gnome3.c @@ -270,6 +270,11 @@ main (int argc, char *argv[]) " falling back to curses\n"); pinentry_cmd_handler = curses_cmd_handler; } + else if (is_gcr_installed ()) + { + fprintf (stderr, "No GCR found, falling back to curses\n"); + pinentry_cmd_handler = curses_cmd_handler; + } #endif --8<---------------cut here---------------end--------------->8--- I do not know how to test for GCR availability, though.

Is this analysis missing anything? I would like to implement a method to make it easier to show the problem to the user. For me it is easy to debug becuase I know how to use watchgnupg but users only see the output of gpg (if at all) and not the gpg-agent logs. This could be implemented by extending the PINENTRY_LAUNCHED notification we already use between gpg and gpg-agent to print a diagnostic and a status line with the type of the pinentry in use and a couple of flags: [GNUPG:] PINENTRY_LAUNCHED <pid> <type> <version> <flags> <type> would be gtk/gnome/qt and flags can be used to indicate the chosen fallback. Requires some additions to the pinentry, though. Would this be helpful? Salam-Shalom, Werner -- Die Gedanken sind frei. Ausnahmen regelt ein Bundesgesetz.
