When I try to use "gpg --gen-key" (v2.1.2 on archlinux) with an user I just created ("backtest"), it works when I open a terminal for that, but not when I'm logged in with another user and then "su -l backtest".
That's what I'm running:
[backtest@server ~]$ echo "pinentry-program /usr/bin/pinentry-curses" >.gnupg/gpg-agent.conf
[backtest@server ~]$ echo RELOADAGENT | gpg-connect-agent
OK
[backtest@server ~]$ GPG_TTY=`tty` gpg --gen-keygpg
and that's what I get:
We need to generate a lot of random bytes. It is a good idea to perform
some other action (type on the keyboard, move the mouse, utilize the
disks) during the prime generation; this gives the random number
generator a better chance to gain enough entropy.
gpg: agent_genkey failed: Operation cancelled
Key generation failed: Operation cancelled

maybe this is relevant, but the pinentry is done in a kind of a dialog, like this image: http://www.soum.co.jp/misc/_images/gpg-agent.png

suchanges the UID of your shell, but your window manager is still running under your UID — and therefore,gpgmight not have the necessary privileges to talk directly to the window manager. – Scott – 2015-04-06T05:12:40.400hm, that makes some sense. But can it detect mouse movements on a "real" local terminal? – Lem0n – 2015-04-06T05:20:35.933
