我看到还有其他主题,但没有答案,所以我将尝试添加更多细节。这不过,帖子中有类似的主题:
语境
无论是否插入 Dell D600) 底座,启动笔记本电脑时都会出现症状,但是插入底座后需要多次重新启动才能使底座正常运行并启用屏幕和键盘/鼠标。启动后系统稳定。
此外,我不确定这是否是转移注意力的借口,但我似乎记得这种情况只在从 20.x 升级到 22.04 后才出现。我确实在网上看到了有关更新 BIOS 的提示,但目前我还没有信心开始更新 BIOS 并可能损坏机器。它非常适合我的需求。

最后,我不得不彻底清理 DisplayLink 驱动程序和 dkms,因为它彻底毁了我的机器。它无法启动到 GUI,不得不重新安装核心文件。evdi 确实搞砸了,但现在似乎很稳定。
dkms 状态的输出:

evdi/1.9.1: added
提前感谢您,虽然这不会给我带来太多困扰,但我非常希望能够拥有一次我以前享受过的干净、无错误的启动。
