"pinentry-program pinentry" is probably the same as no line at all (it
is the default).  I strongly recommend sticking with the simplest
default configuration possible, so removing that line is good.

but note that pinentry-program expects the full path
(e.g. /usr/bin/pinentry-qt), not the unadorned program name.  I think
that's an unnecessarily broken behavior that only gets in the way of
debugging. i've just documented that concern upstream at
https://dev.gnupg.org/T4588 (this is a separate issue from the current
discussion, of course).

You can also use "gpgconf --kill gpg-agent"

this can also be run as:

     gpg-connect-agent 'GET_CONFIRMATION Hello' /bye

Is pinentry-gnome3 still installed?  If you don't want a grab, it should
not be installed.


 * You should have only pinentry-qt installed (and no other `pinentry-*` packages)

 * You should have no `pinentry-program` line in your gpg-agent.conf.

 * "readlink -f $(which pinentry)" should point to /usr/bin/pinentry-qt

 * You should terminate your running gpg-agent after making all of the
   above changes, with "gpgconf --kill gpg-agent"

if all of these conditions are met, then the following should give you a
QT-based, non-grabbing confirmation prompt:

    gpg-connect-agent 'GET_CONFIRMATION Hello' /bye

If this doesn't work for you, then something else is more seriously
wrong, and i'd like to understand it better.
