我想在带有 Arch Linux ARM 的 Raspberry Pi 3 上启动进入图形会话。我已经安装了xlogin（https://wiki.archlinux.org/index.php/Systemd/User#Automatic_login_into_Xorg_without_display_manager）。
内容~/.xinitrc
#!/bin/bash
cd ~user
openbox >openbox.log 2>&1
当我运行时sudo systemctl start xlogin@user，openbox.log是这样的：
Openbox-Message: Failed to open the display from the DISPLAY environment variable.
的退出代码openbox是1。当我使用openbox-sessioninstead时openbox，输出完全相同。我试图写入$DISPLAY文件，它是:0（所以它是放）。
输出sudo systemctl status xlogin@user
