OpenSUSE XDM SSH_ASKPASS

Every year or so I rebuild my machine and forget how to enable the ssh-askpass tool with ssh-agent from XDM display manager

cp /etc/X11/xdm/sys.xsession ~/.xession

cp ~/.xinitrc.template ~/.xinitrc

# Add ssh agent config for loading keys

if test -S "$SSH_AUTH_SOCK" -a -x "$SSH_ASKPASS"; then
        ssh-add ~/.ssh/id_nameofprivatekey < /dev/null
fi
