为什么？

我发现这个相关问题根据其接受的答案，我应该进行/etc/X11/Xwrapper.config如下编辑：

allowed_users=anybody
needs_root_rights=yes

我这样做了，但这对我来说并没有什么改变。

评论似乎表明这startx在 Ubuntu 中是错误的。为什么会这样？如果是这样，也许我最初的问题的答案是“startx 不再可能，因为......”，或者“使其成为可能会有......缺点”之类的？

root@gcomputer:~# dpkg-reconfigure x11-common
update-rc.d: warning: start and stop actions are no longer supported; falling back to defaults
insserv: warning: script 'S04powernowd.early' missing LSB tags and overrides
insserv: warning: script 'powernowd.early' missing LSB tags and overrides

不确定这是什么意思。

答案1

您可以尝试重新配置dpkg-reconfigure x11-common

来源：3 个不同的 14.04 LTS 系统上未修改的 /etc/X11/Xwrapper.config 文件。请注意，16.04 没有此文件。

附注：我的系统上的同一源包含以下行：allowed_users=console而不是allowed_users=anybody

后来找到相关来源：http://karuppuswamy.com/wordpress/2010/09/26/how-to-fix-x-user-not-authorized-to-run-the-x-server-aborting/

答案2

对于最新版本，这重新配置操作不起作用。您应该安装旧版包：

sudo apt-get install --no-install-recommends xserver-xorg xserver-xorg-legacy xinit xterm

并且您应该运行重新配置操作来授予权限：

sudo dpkg-reconfigure xserver-xorg-legacy

在控制台菜单中请选择任何人

您还应该检查用户是否属于权限组，例如视频组为例。
