Systemd service
Hi there.
I wrote a Systemd .service file to replace copying the .desktop file into autostart.
journalctlDesktopNotification.service
[Unit]
Description=Shows desktop notifications for journalctl errors
Requires=default.target
StartLimitInterval=120
StartLimitBurst=20
[Service]
Type=simple
ExecStart=/usr/bin/journalctl-desktop-notification
Restart=on-failure
RestartSec=6
KillMode=process
[Install]
WantedBy=default.target
It belongs into /etc/systemd/user if installed manually or /usr/lib/systemd/user if installed by a package.
Then run systemctl daemon-reload followed by systemctl --user enable --now journalctlDesktopNotification.service.
You may use it (or not) if you think it's cleaner.
