我正在使用 Ubuntu 20.04 focal fossa。今天软件更新更新了我的计算机，可能还更新了我的 nvidia 驱动程序，这损坏了它。现在我的分辨率不是 1920x1080，而是 1024x768，我无法修复它。
我彻底地在 Google 上搜索并尝试了很多解决方案，但都没有奏效。
我尝试禁用nouveau。
我尝试禁用安全启动（它一开始就没有打开）
apt我尝试通过( )重新安装驱动程序nvidia-driver-390，多次，使用--reinstall，并使用purge
我尝试编辑 grub 文件并添加nomodeset到行GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
我尝试了 xrandr--newmode和--addmode，这使得我的设置中出现了一个新的分辨率选项，但是当我按下它时，什么也没有发生，它只是恢复到 1024x768。
我还没有尝试安装旧驱动程序或使用 nvidia 网站上的 .run 文件手动安装。请帮忙
以下是各种命令的输出：

答案1
现在似乎有很多人都遇到了这个问题。包括我自己，但我设法解决了它。虽然我不是 Linux 专家，但我将尽可能详细地解释。我所知道的一切基本上都是从互联网上复制粘贴代码，希望它能起作用。
我运行的是 nvidia gtx 960、460.39 驱动程序，并双启动 ubuntu 20.04 和 windows 10。windows 上没有问题。当我启动 ubuntu 时，我立即遇到严重的卡顿，我的辅助显示器不工作，所有窗口都在屏幕上从上到下缓慢绘制。
上次我遇到这个问题（约 2 个月前），简单的重新安装驱动程序对我来说就有用了。
sudo apt install --reinstall nvidia-driver-460
今天这个方法对我不起作用。我尝试使用以下命令清除驱动程序：
sudo apt autoremove --purge nvidia-driver-460 && sudo apt install nvidia-driver-460
但这也不起作用。使用后nvidia-smi我得到了以下结果：
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
使用sudo dkms status我得到以下结果：
nvidia, 460.39, 5.8.0-45-generic, x86_64: installed (WARNING! Diff between built and installed module!) (WARNING! Diff between built and installed module!) (WARNING! Diff between built and installed module!)
谷歌搜索让我找到了这个nvidia 论坛帖子，似乎存在同样的问题。巧合的是，截至撰写此回复时，该帖子发布时间还不到 20 小时。从论坛帖子（特别是评论 #7）中，我使用了以下代码：
sudo dkms remove nvidia/460.39 --all
sudo dkms install --force nvidia/460.39 -k $(uname -r)
sudo update-initramfs -u
sync
reboot
就像一个典型的受过训练的猴子用户一样，我使用这些命令时并不知道它们的作用。但重启后我的系统运行正常。希望这对某些人有帮助。
答案2
从 nvidia 网站来看，他们在 2021 年 1 月发布了 390.141，修复了内核 5.8 下安装失败的问题。
我在新安装的 ubuntu 18.04 上进行了测试，从“附加驱动程序”中选择了 390.141，并使用了主线内核工具中的内核 5.8.0。现在可以正常工作了。
因此，现在我要从主线中删除所有较新的内核，删除 nvidia 390.141 并重新使用 x.org 驱动程序。升级到 ubuntu 20.04.2。我使用 ubuntu 主线内核工具安装内核 5.8.0，并从“附加驱动程序”选项卡安装 390.141 驱动程序。Viola，我在内核 5.8.0 中有一个正常工作的 nvidia 390.141。
答案3
我发布这个答案只是为了帮助任何遇到和我一样问题的人。我的屏幕也有同样的问题，这是因为它没有检测到 NVIDIA 驱动程序。然而，即使我正确安装了所有东西，它仍然失败了。
最后，问题出在我几天前安装的 gnome 插件上。因此，如果重新安装 NVIDIA 后问题仍然存在，我建议检查一下您最近可能安装的任何 GNOME 插件。
