[Pkg-xfce-devel] Bug#852873: xfce4-session: ssh-agent is started even if user wishes to use gpg-agent's ssh agent protocol

[Teemu Likonen]

Package: xfce4-session
Version: 4.12.1-5
Severity: normal

Dear Maintainer,

XFCE starts ssh-agent even if user wishes to use gpg-agent's ssh agent
protocol. The details:

I have a Debian testing XFCE4 desktop system and use gpg-agent to
manager ssh-agent protocol as well. There is "enable-ssh-support" in
~/.gnupg/gpg-agent.conf file which, among other things, makes
/etc/X11/Xsession.d/90gpg-agent file set variable SSH_AUTH_SOCK so
that /etc/X11/Xsession.d/90x11-common_ssh-agent file _doesn't_ start
ssh-agent.

That works just fine (i.e., ssh-agent is not started) if I start a bare
X session like

    $ startx /usr/bin/xfce4-terminal

but if I start a full XFCE4 session (/usr/bin/startxfce4) then something
(but certainly not 90x11-common_ssh-agent) starts "ssh-agent -s" process
and overrides SSH_AUTH_SOCK variable.

I think XFCE session should not start ssh-agent nor should it override
SSH_AUTH_SOCK variable (which "belongs" to gpg-agent in this use case).
