这里是菜鸟。
我在尝试安装 Linux Homebrew 时搞砸了一些东西，现在我无法登录到我的主桌面（当我正确输入我的凭据时，我被踢出）。从那时起，我卸载了该软件并尝试了一些修复方法，我将在这里列出这些方法以及其他一些相关信息（我希望如此）
当前操作系统：
Linux 5.4.0-40-通用#44 Ubuntu SMP x86_64
显卡
00:02.0 VGA 兼容控制器：英特尔公司 UHD Graphics 620 (Whiskey Lake)
我尝试过的故障排除：
- 遵循此堆栈交换中的最佳答案：Ubuntu 陷入登录循环
- 安装了 libpam-kwallet4 和 libpam-kwallet5，修复了日志文件中出现的错误，但最终似乎只是一个幌子
- 安装 libpam-winbind
- 在 GRUB 中禁用 quiet-splash
- 已启用 nomodeset
- 重新安装 xorg
- Ubuntu 从 19.10 更新至 20.04
一个特别让我印象深刻的错误（我已经忘记是怎么得到这个错误的......可能是来自startx？）如下：
FATAL: Module fbcon not found in directory /lib/modules/5.4.0-40-genericintel
这看起来很可怕，所以可能是相关的
以下是 Xorg.0 日志文件中我尚未弄明白的一些其他错误：
EE: Screen 0 deleted because of no matching config section
EE: Open /dev/dri/card0: No such file or directory
EE: No devices detected
EE: Systemd-logind: failed to get session: PID 967 does not belong to any known session
最后，这是我尝试登录时 auth.log 文件中的一段代码。

可能还值得一提的是，我现在正在使用远程桌面（ctrl + alt + f4 -> startx），有些应用程序拒绝启动。不确定这是否相关。如果我可以提供任何其他信息，请告诉我。
