从 18.10 升级到 19.04。启动时 GDM 正常启动，输入密码后无法启动 GNOME。它返回到 GDM
这是一台 Nvidia Optimus 笔记本电脑。我从 USB 运行 Dingo 并将其安装到测试分区中。它识别所有内容（使用 nouveau 而不是 Nvidia blob）。
日志显示：
WARNING: App 'org.gnome.Shell.desktop' exited with code 1
Unrecoverable failure in required component org.gnome.Shell.desktop
WARNING: App 'org.gnome.Shell.desktop' respawning too quickly
CRITICAL: We failed, but the fail whale is dead. Sorry...
使用 Xorg 和 Wayland 的两个 mutter 会话都以同样的方式失败。旧的 metacity“GNOME Flashback”启动正常（但 indicator-datetime-service 会占用所有 CPU 和内存，而且如果我将其关闭，它也不会停止重生）。
尝试使用 lightdm 代替 GDM。同样失败。
尝试重新安装 gnome-session 包。没有任何变化。
通过 journalct -xe 获取的所有日志。
欢迎任何有关如何调试此东西的建议。
后来，我意识到我无意中启用了“建议的”存储库（在我的 cosmic 安装中）。将 gnome-shell（“3.32.1-1ubuntu1~19.04.1”降级为“3.32.0+git20190410-1ubuntu1”）、mutter 和其他软件包（使用固定优先级），但问题仍然完全相同。
这是日志的较长摘录（现在使用 Budgie）：

答案1
现在已修复！
我尝试禁用所有扩展，包括用户扩展，但无济于事。问题出在显示世界时钟的内置扩展上。我不得不从 CLI [1] 重置我的世界时钟位置。
据称该问题已经修复（相同的 GitLab 问题）因此将来不会再发生这种情况。
