startx作为用户失败
在Ubuntu 16.04上：

我发现了这个相关的问题 。 根据其接受的答案，我应该编辑/etc/X11/Xwrapper.config如下：
allowed_users=anybody needs_root_rights=yes
我做到了，但这对我没有任何改变。
这些评论似乎表明startx在Ubuntu中被打破了。 这是为什么？ 如果是这种情况，也许我原来的问题的答案是“startx不再可能因为……”，或者“让它成为可能会有……缺点”或者左右？
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
不确定这意味着什么。
您可以尝试使用dpkg-reconfigure x11-common
来源：3个不同的14.04 LTS系统上未经修改的/etc/X11/Xwrapper.config文件。 请注意，16.04没有此文件。
旁注：我系统上的相同源代码包括： allowed_users=console而不是allowed_users=anybody
