While troubleshooting my ssh-agent setup, I discovered that an extra ssh-agent instance was running, and I have no idea what is starting this.
What I want is to have ssh-agent run as a systemd user service (following the instructions at <https://wiki.archlinux.org/index.php?title=SSH_keys&oldid=571850#Start_ssh-agent_with_systemd_user>), but the other instance is interfering. Here is where it is in the process tree (via htop): 1756 ├─ /lib/systemd/systemd --user 31808 │ ├─ /usr/lib/flatpak/flatpak-session-helper 26143 │ ├─ /usr/lib/dconf/dconf-service 22233 │ ├─ /usr/bin/dunst 22204 │ ├─ /usr/lib/xdg-desktop-portal/xdg-desktop-portal-gtk 22187 │ ├─ /usr/lib/flatpak/xdg-permission-store 22184 │ ├─ /usr/lib/flatpak/xdg-document-portal 22180 │ ├─ /usr/lib/xdg-desktop-portal/xdg-desktop-portal 21243 │ ├─ /usr/bin/dirmngr --supervised 18747 │ ├─ /usr/lib/gvfs/gvfsd-trash [snip] 18672 │ ├─ /usr/lib/gvfs/gvfs-udisks2-volume-monitor 18534 │ ├─ /usr/lib/gvfs/gvfsd-metadata 5759 │ ├─ /usr/bin/gpg-agent --supervised 1934 │ ├─ /usr/lib/x86_64-linux-gnu/gconf/gconfd-2 1856 │ ├─ /usr/lib/gvfs/gvfsd 1849 │ ├─ /usr/lib/at-spi2-core/at-spi2-registryd --use-gnome-session 1835 │ ├─ /usr/lib/at-spi2-core/at-spi-bus-launcher 1847 │ │ └─ /usr/bin/dbus-daemon [snip] 1790 │ ├─ /usr/bin/pulseaudio --start --log-target=syslog 1932 │ │ └─ /usr/lib/x86_64-linux-gnu/pulse/gconf-helper 1771 │ ├─ /usr/bin/dbus-daemon [snip] 1762 │ ├─ /usr/bin/ssh-agent -t 2m -D -a /run/user/1000/ssh-agent.socket 1761 │ ├─ /usr/bin/mpd --no-daemon 1757 │ └─ (sd-pam) 1763 │ │ └─ i3 1876 │ │ ├─ /usr/bin/ssh-agent i3 1833 │ │ ├─ /usr/lib/policykit-1-gnome/polkit-gnome-authentication-agent-1 1832 │ │ └─ clipit (The ssh-agent instance with PID 1762 is the one I want; PID 1876 is the unwanted instance.) I need to know how to either a) disable the instance started under "(sd-pam)", so I can use my systemd user service, or b) configure the instance started under "(sd-pam)", and use that instead of my system user service. I am using lightdm to start X, and my session is the i3 WM. In case it's relevant, I also start /usr/lib/policykit-1-gnome/polkit-gnome-authentication-agent-1 in my ~/.xsessionrc file. I am running Debian 9.8 on x86_64. Thanks, Aidan Gauland
