20.04 更新后登录循环 - startx 不起作用

我今天早上更新（自动更新程序）后遇到了登录循环，我找到的建议解决方案没有帮助。含义：

  • 自动登录已禁用/etc/gdm3/custom.conf
  • 权限.Xauthority是-rw------- username username
  • 所有者/tmp是root root并且权限是drwxrwxrwt

我注意到当我从控制台尝试时 xserver 没有启动。我无法显示整个日志文件，因为它显然“看起来像垃圾邮件”（这让我抓狂），所以这是最后一部分：

有什么提示可能出了什么问题吗？我有点绝望，应该重新开始使用这个站，我会非常感激任何帮助。

亲切的问候。

更新后缺少 xorg.conf。运行后会在工作目录中Xorg -configure创建。将其复制到 /etc/X11/ 文件夹并重新启动 x-server 即可解决问题。xorg.conf.newcp xorg.conf.new /etc/X11/xorg.conf
