![Ubuntu 22.04 上的 Nvidia USB-C 黑屏](https://linux22.com/image/1194742/Ubuntu%2022.04%20%E4%B8%8A%E7%9A%84%20Nvidia%20USB-C%20%E9%BB%91%E5%B1%8F.png)
问题:
- 我有一个笔记本电脑和英伟达在Ubuntu 22.04.02。
- 突然一个月前,USB-C 外接显示器就黑屏了——没有错误,什么都没有,只是黑屏。
- 插入 USB-C 时,显示器显示(无信号)。
- 它仍然是几个月前安装的 Ubuntu 版本。我只运行了常规更新。
有效的方法:
- 我双启动到 Windows,并且运行完美。
我尝试过什么:
概述:
- 联想 16p 笔记本电脑,AMD CPU
- LG 显示器 USB-C
- Ubuntu 22.04.2 LTS
- Linux 内核 5.15.0-40-通用
关于:
- CPU 中有一个 AMD GPU
- 它有一个专用的 Nvidia(笔记本电脑内部)
- 这两种 GPU 都是笔记本电脑开箱即用的。
几个月前它还能用。同样的机器,同样的安装。现在它不能用了。
我能做些什么?(请帮忙 : )

答案1
解决方案:
我在这里读了这篇文章: Ubuntu 22.04.1 LTS,RTX 3060Ti,无法分配 NvKmsKapiDevice
- 我做到了:
sudo apt remove nvidia* && \
sudo apt autoremove && \
sudo apt install --reinstall nvidia-driver-470
2.我必须进入 Nvidia X 服务器设置
sudo apt install nvidia-settings
nvidia-settings
- 进入 PRIME 并选择 Full Power。重启后,在登录屏幕上,外接显示器将显示 ubuntu
