Quero iniciar um aplicativo gráfico via systemd. Eu tentei fazer isso via udev antes, mas o aplicativo é encerrado após o término da regra. Funciona quando executo o aplicativo diretamente via systemd, mas não quando executo o script que inicia o aplicativo com algumas restrições.
Meu arquivo de serviço é assim:
[Unit]
Description=App starter
[Service]
Type=oneshot
RemainAfterExit=yes
Environment=DISPLAY=:0
Environment=HOME=/home/user/
ExecStart=/home/user/runApp
[Install]
WantedBy=multi-user.target
journalctl -xe me dá

Aqui está o roteiro. Pode ser devido à execução em segundo plano &
? Preciso disso porque quero reutilizar o script.
#!/bin/bash
if pgrep app
then
echo App is running
wmctrl -x -a app
wmctrl -x -r app -b "add,maximized_vert,maximized_horz"
else
echo App is not running
/usr/bin/app & disown
fi

Pode ser um problema de permissão.
/home/user
geralmente não permite que nenhum outro usuário os acesse e sistemas de segurança como apparmor e selinux geralmente proíbem tal uso.
Se você quiser usar um script no systemd, é melhor colocá-lo no /usr/local/bin
.
