我最近将笔记本电脑（双启动）从损坏的 20.04 升级到 22.04。它最初运行良好，大约一周后就出现了问题。
最初，操作系统无法识别内置屏幕，因此我认为问题出在图形上。我有一台 HP Victus 16-e0007ni，配备 NVIDIA GeForce RTX 3050 Ti Mobi 和内置 AMD 显卡。以下是可能有帮助的命令的结果。
~$ lspci | grep VGA
01:00.0 VGA compatible controller: NVIDIA Corporation GA107M [GeForce RTX 3050 Ti Mobile] (rev a1)
06:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Cezanne (rev c5)
然后我从软件更新应用程序作为自定义安装的驱动程序. 使用专有 NVIDIA 驱动程序
~$ sudo apt install nvidia-driver-510
~$ reboot
和类似的命令（即 470 等），在测试所有命令之后，发生了同样的事情。
他们修复了笔记本电脑内置显示器无法识别的问题，但是没有一个可以识别我的外接显示器。此外，我尝试了 X.org 驱动程序。第一次启动时它就正常工作了，但是从那时起，我必须先启动到安全模式才能启动它。所以总而言之，我现在改回了，使用
~$ sudo ubuntu-drivers autoinstall
至 nvidia-driver-515。
无论如何，这里有一些可疑的事情：
nvidia-smi 抛出了这个错误。这让我相信加载图形驱动程序时出现了错误。
~$ nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

答案1
我有 ubuntu 22.04，当我将 nvidia 驱动程序从 480 更新到推荐的 515 时也发生了同样的事情（外部显示器没有信号）。
将内核升级到 5.19（而不是当前的 5.15）解决了我的问题。
要更新内核（大部分是从内核更新）
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.19.3/amd64/linux-headers-5.19.3-051903-generic_5.19.3-051903.202208211442_amd64.deb
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.19.3/amd64/linux-headers-5.19.3-051903_5.19.3-051903.202208211442_all.deb
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.19.3/amd64/linux-image-unsigned-5.19.3-051903-generic_5.19.3-051903.202208211442_amd64.deb
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.19.3/amd64/linux-modules-5.19.3-051903-generic_5.19.3-051903.202208211442_amd64.deb
sudo dpkg -i *.deb
sudo reboot -n
此外我必须对内核进行签名，因为 Windows 具有安全启动的双启动功能，并且 repo 中的内核是不是已签名。确实按照此处的说明进行操作标志核
（这里最后一步有一个 bash 命令用于删除未签名的内核，但我看不懂。为了安全起见，我使用了普通命令rm）。
