20.04 黑屏，无桌面会话，org.gnome.keyring.systempropter 问题

我的 20.04 安装突然无法启动到 gnome。它只是启动到可怕的黑屏，光标闪烁。我可以通过 ctrl-alt-F* 进入虚拟控制台，但仅此而已。

journalctl -xe 生成以下内容：

我在 Arch 论坛上找到了一些解决这个问题的方法，但仅此而已。任何想法都值得赞赏。

谢谢！

我也遇到了这种情况。我试图解决不需要的打印机不断加载的问题。在停止与该问题相关的服务后，我重新启动并出现了可怕的黑屏。

经过 4 个小时的搜索和尝试，包括上述启动修复，我最终查看了我的视频驱动程序。在命令提示符下，我输入

sudo apt 删除 nvidia-340

此后我重新启动并启动到我的桌面环境。

不确定这是否会对您有帮助，但对我来说确实有用。

您有外部 Ubuntu 安装 USB 吗？如果有，请启动 USB，然后选择“尝试 Ubuntu”。这将创建一个临时的 Ubuntu 会话。您现在可以尝试以下操作：

  1. 将 Boot-Repair 安装到另一个 USB，如下所述：https://help.ubuntu.com/community/Boot-Repair然后尝试运行它来修复当前系统。

或者

  1. 运行实时 USB 版本时挂载安装 Ubuntu 的磁盘并从命令行修复它。

它就像运行一个可以运行的 Ubuntu，您可以在其中下载并安装所需的所有应用程序，以便拥有完全访问权限来修复您的主安装。

我建议您在尝试修复或以其他方式配置和修改主磁盘之前，通过 USB 试用版从主磁盘获取对您很重要的文件，然后将其备份到第三个 USB。
