无法启动5.13内核恐慌

Question

问题描述

系统不会在5.13内核上启动，目前在没有eGPU的5.11上“工作”。系统不会在eGPU连接的任何当前安装的内核上启动。

在5.13内核上，引导甚至没有达到加密密码步骤，只会产生以下错误的内核恐慌。在5.11内核上，连接了eGPU，它总是通过加密密码步骤，但并不总是引导到gnome。有时候你只会看到一个闪烁的下划线(一旦我能够把ctl，alt-f3放到tty3中)，有时只有连接到eGPU的监视器显示gnome，内部显示了联想的徽标。

此外，当没有连接到eGPU和5.11内核时，它似乎仍然没有完整的功能。例如，内部显示亮度键不工作；HDMI端口不工作。

如果所描述的问题是两个不同的问题，请表示歉意。该系统和所有提到的功能在20.04LTS上连接和不连接eGPU之前都运行良好。(事后看来，我不应该升级lol)

Answer 1

通过5.13.0-28内核更新，解决了内核恐慌问题。

没有引导到gnome问题和其他“不寻常”的功能问题，通过清除和重新安装gdm来解决。
