我想透過 systemd 啟動圖形應用程式。我之前嘗試透過 udev 執行此操作，但應用程式在規則終止後被終止。當我直接透過 systemd 運行應用程式時它可以工作，但當我運行帶有一些約束的啟動應用程式的腳本時它就不起作用。
我的服務文件如下圖所示：
[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 給了我

這是腳本。可能是由於後台運行所致&？需要這個，因為我想重用該腳本。
#!/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
答案1
可能是權限問題。
/home/user通常不允許任何其他使用者存取它們，並且像 apparmor 和 selinux 這樣的安全系統通常禁止這種使用。
如果你想在systemd中使用腳本，你最好把它放在/usr/local/bin.
