I assume you want to use gpg-agent to act as ssh-agent so you can use
your smartcard for ssh?

You can put that in your ~/.profile:

GPG_TTY=$(tty)
export GPG_TTY
#/usr/local/bin/gpg-agent --daemon
SSH_AUTH_SOCK="$HOME/.gnupg/S.gpg-agent.ssh"; export SSH_AUTH_SOCK

You can uncomment the gpg-agent launcher line, but I prefer to start
it by hand when needed. If you uncomment this line new agent wont
spawn if there is already agent running.

You can also set this in ~/.gnupg/gpg-agent.conf:
enable-ssh-support
pinentry-program /usr/local/bin/pinentry-qt5

This will allow you to use gpg with ssh. If you want to use usb
smartcard with private key you also need scdaemon. All options
explained here:
https://www.gnupg.org/documentation/manuals/gnupg/Agent-Options.html

Pinentry is the pop up window that will ask for card pin. For KDE that
would be QT5 variant, but these are available:
pinentry-1.1.1
pinentry-curses-1.1.1
pinentry-efl-1.1.1
pinentry-fltk-1.1.1
pinentry-gnome3-1.1.1
pinentry-gtk2-1.1.1
pinentry-qt5-1.1.1
pinentry-tty-1.1.1

Hope that helps :-)
