几周前，在将内核更新至 5.8.0-36 后，我无法启动笔记本电脑。通过安装 nvidia-driver-460 解决了这个问题。通过安装 linux-modules-extra-5.8.0-36-generic 解决了无线和亮度控制的后续问题。无法识别外接显示器（现在仍然无法识别）。
昨天（重新启动后）我遇到了以下问题：
- 系统挂起后无法唤醒（必须关闭电源）
- 屏幕亮度控制又消失了
- 正常启动后我无法登录（密码无法识别？），如果我启动到恢复模式然后恢复，我就可以登录。

答案1
我对所有这些问题的解决方案是：
sudo dpkg -P $(dpkg -l | grep nvidia-driver | awk '{print $2}')
sudo apt autoremove
sudo apt install xserver-xorg-video-nouveau
开源驱动程序似乎有点慢，但至少我可以登录并且屏幕是亮的！
