为什么？

我找到了这个相关的问题。根据其公认的答案，我应该按以下方式编辑/etc/X11/Xwrapper.config：

allowed_users=anybody
needs_root_rights=yes

我这么做了，但这对我没什么改变。

这些评论似乎表明，startx在Ubuntu中被破坏了。为什么会这样呢？如果是这样的话，也许我原来问题的答案是"startx不再可能了，因为.“，或者”让它成为可能会有.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

不知道这意味着什么。

Answer 1

您可以尝试使用dpkg-reconfigure x11-common重新配置

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

附带注意:我的系统上相同的源代码包括行：allowed_users=console而不是allowed_users=anybody

相关来源稍后发现：http://karuppuswamy.com/wordpress/2010/09/26/how-to-fix-x-user-not-authorized-to-run-the-x-server-aborting/

Answer 2

对于最后一个版本，此重新配置操作不起作用。您应该安装遗留程序包：

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

并且您应该运行reconfigure操作以授予权限：

sudo dpkg-reconfigure xserver-xorg-legacy

在控制台菜单中，请选择任何人

另外，您应该检查用户是否在权限组中，例如视频组。
