Greetings,
I am trying to write a service file for a tool called devilspie2.
% systemctl --user cat devilspie.service
# /home/mzagrabe/.config/systemd/user/devilspie.service
[Unit]
Description=devilspie
[Service]
ExecStart=/usr/bin/devilspie2
[Install]
WantedBy=default.target
# /home/mzagrabe/.config/systemd/user/devilspie.service
[Unit]
Description=devilspie
[Service]
ExecStart=/usr/bin/devilspie2
[Install]
WantedBy=default.target
which I enabled via:
% systemctl --user enable devilspie.service
but it is not successfully starting on boot/login:
% systemctl --user status devilspie.service
● devilspie.service - devilspie
Loaded: loaded (/home/mzagrabe/.config/systemd/user/devilspie.service; enabled; vendor preset: enabled)
Active: failed (Result: exit-code) since Tue 2019-08-06 13:39:23 CDT; 3min 14s ago

The actual reason isn't making it into the systemctl output, but does show in the journal (under the "unknown" log entry [826]):
% journalctl --user --since '10 minutes ago'
[...]

So...
It looks like devilspie2 does not successfully start under a user systemd instance due to "cannot open display".
Since I log in via lightdm I am wondering what I am missing.
Any ideas or pointers on how to properly start devilspie2 under a user systemd instance?
Thanks for any help!
