Xserver 权限被拒绝 tty7

我有一个装有 kodi 的 Linux 机器和以下 systemd 脚本，用于在启动时启动 kodi：

[Unit]
Description = kodi-standalone using xinit
After = systemd-user-sessions.service network.target sound.target network-online.target

[Service]
User = kodi
Group = kodi
Type = simple
PAMName=login
ExecStart = /usr/bin/xinit /usr/bin/dbus-launch --exit-with-session /usr/bin/openbox-session -- :0 -nolisten tcp vt7
Restart = on-abort

[Install]
WantedBy = multi-user.target

在 Ubuntu 15.10 下，这个功能运行正常，但升级后就不行了。服务无法启动

那么我该如何解决这个问题？请注意，使用 15.10 一切正常！

谢谢！

答案1

我今天遇到了这个错误。经过一番调查，解决方案如下通过 Kodi 操作指南.第5章说：

从 Ubuntu 16.04（Xenial Xerus）开始，您需要安装并重新配置该软件包xserver-xorg-legacy。

它在我的设备上运行良好。

答案2

好吧，这不是最好的解决方案，但在启动 kodi 之前将 systemd 启动作业更改为 chmod/dev/tty7似乎可以“修复”它。如果有人有更好、更适合 ubuntu 的方法，请告诉我 :D

[单元]
描述 = kodi-standalone 使用 xinit
之后 = systemd-user-sessions.service network.target sound.target network-online.target

[服务]
用户 = kodi
群组 = kodi
类型 = 简单
PAMName=登录
ExecStartPre=/bin/chmod 777 /dev/tty7
权限启动仅=true
ExecStart = /usr/bin/xinit /usr/bin/dbus-launch --exit-with-session /usr/bin/openbox-session --:0 -nolisten tcp vt7
重新启动 = 中止

[安装]
WantedBy = 多用户.目标

答案3

如果您正在使用 systemd，那么可能使其发挥作用的另一个想法是让 systemd 充当 X 和 root 权限之间的代理。

这需要安装libpam-systemd以便systemd-logind开始在控制台上正常工作（参见Debian 9 发布说明：Xorg 服务器不再需要 root 权限)，并从使用普通的切换xinit到使用startx包装器（参见Debian 错误 #801401）。

我不知道这个 Kodi 用例的具体情况，但在研究一般问题时偶然发现了这个问题，所以我认为我最好写下来以帮助其他人将这些点联系起来。
