我的操作系统是 Ubuntu 18.04。
我想启用 NVENC 编码器进行 OBS 录制。我遵循了以下教程：https://scottlinux.com/2016/09/12/how-to-enable-nvidia-nvenc-for-obs-in-linux/
但是在第 2 步，我犯了一个错误。我从 ubuntu 存储库安装了 Cuda，而不是仅仅复制 Cuda.h。
我从存储库 (apt get cuda) 安装 Cuda 后，重新启动了笔记本电脑，但无法启动 GUI。卸载 Cuda 后，我可以再次启动 GUI，但卸载 cuda 时我也丢失了 nvidia 驱动程序。
然后，我尝试根据本指南重新安装 nvidia 驱动程序：https://www.cyberciti.biz/faq/ubuntu-linux-install-nvidia-driver-latest-proprietary-driver/ 我的 vga 是 Nvidia 930MX，并且我安装了 nvidia-driver-435。
安装驱动程序时没有任何错误。但是当我重新启动笔记本电脑时，我无法再次启动 GUI。我尝试了另一个版本 nvidia-driver-390、nvidia-driver-430。但没有任何效果。
现在，我决定使用 Intel HD 来应急。但在启动时（dmesg 日志），我收到此错误：

我想找回我的 nvidia 驱动程序。任何人都可以解决这个问题或给出建议的解决方案。
更新 1：现在我按照以下步骤解决了 nvidia 驱动程序错误问题。
- 删除所有 nvidia 包并重新启动
sudo apt purge nvidia-driver-440
sudo apt autoremove
- 从运行二进制文件安装 nvidia 驱动程序，可在nvidia 网站。. 如果出现 dkms 错误，请运行：
sudo apt install dkms
如果出现无法加载“nvidia-drm”内核模块的错误，请删除 xorg.conf
sudo rm /etc/X11/xorg.conf
然后安装二进制 nvida 驱动程序。
我正在等待您的帮助，以找到在 OBS 上启用 nvenc 编码器的最佳方法。
