Short description, what i'm searching for:

I want to have a detached tmux session automatically started as a systemd user service. Inside that, offlineimap should start and decrypt my login credentials. The graphical variant of pinentry should ask me for the password for decrypting my login credentials, when I attach to the session. For managing my login credentials, I want to use the program pass.

What I've got so far:

The desired Behavior works perfectly and reproducibly (starting from reboot), when i start the user service after I've logged into my system.

But unfortunately it doesn't work when I do "symstemctl --user enable mail.service" and reboot:

$ systemctl --user status mail
● mail.service - load offlineimap for all mail accounts inside tmux
Loaded: loaded (/home/toogley/.dotfiles/systemd/user/mail.service; enabled; vendor preset: enabled)
Active: inactive (dead)

$ tmux attach-session -t mail
can't find session mail

I have no idea, what i could analyze or what might be the reason. Does somebody has tips how to address this issue?

Thanks a lot!

My mail.service

Description=load offlineimap for all mail accounts inside tmux
After=network.target graphical.target

ExecStart=/usr/bin/tmux new-session -d -s mail -n dev 'export GPG_TTY=$(tty) && \
ExecStop=/usr/bin/tmux kill-window -t mail

my gpg-agent.service:

Description=GnuPG private key agent

    does journalctl --user give any clues? – meuh Jun 5 '16 at 18:34

    in your mail.service you have After=network.target graphical.target and WantedBy=graphical.target which I dont think is workable. – meuh Jun 5 '16 at 18:49
  • @meuh : Thanks for your suggestions - they were very helpful in finding the problem :D – toogley Jun 6 '16 at 16:59

It seems that what I'm searched for is currently not possible.

Initially I misread the description of graphical.target - I thought this target would be set after the login has happened. Instead, it just sets up the Login Screen (e.g. lightdm). And for "logged into graphical desktop" does currently no target exist.

The ArchLinux Wiki describes a method of starting the window manager per systemd user services - which doesn't work for me, because it depends when the user logs into lightdm.

As a workaround I use an alias for starting my service when I need it.
