Xserver 可以检测到我的外接显示器，但无法检测到我的集成笔记本电脑显示器

我有一台搭载有 Ubuntu 22.04 的联想军团 5（我在使用 Ubuntu 20.04 时遇到了同样的问题，并希望升级到 22.04 可以解决问题，但没有）。2 个外接显示器和笔记本电脑的屏幕。

与侏儒一起。

当我启动计算机时，外接显示器处于非活动状态，直到启动到达 gnome 的登录（即直到 X 服务器），然后笔记本电脑显示器停留在登录屏幕，显示“按 ctrl+c 取消正在进行的所有文件系统检查”，并且外接显示器被检测到并显示 gnome。

如果我按 ctrl+alt+F3 来获取终端，它会出现在我的笔记本电脑屏幕上，而当我使用 ctrl+alt+F1 返回 X 服务器时，它们会出现在外部显示器上。

我有一块 amd 和一块 nvida 显卡/gpu：

sudo lshw -C display 给出

有趣的是，当我这样做sudo X -configure 时

我没有/etc/X11/xorg.conf文件。有趣的是，如果我创建一个/etc/X11/xorg.conf包含以下内容的文件：

Section "ServerLayout"
    Identifier "Layout0"
    Option "AutoAddGPU" "false"
    Screen 0 "IntelScreen"
EndSection

Section "Device"
    Identifier "IntelDevice"
    BusID "PCI:0:2:0"
    Driver "intel" # or maybe "modesetting"?
EndSection

Section "Screen"
    Identifier "IntelScreen"
    Device "IntelDevice"
EndSection

然后外部显示器不再被检测到，但是笔记本电脑屏幕可以工作并且被 xserver 检测到。

我不知何故觉得外接显示器需要 nvidia 驱动程序才能工作，而笔记本电脑屏幕需要非 nvidia 驱动程序才能工作，但我不知道如何实现这一点。

也许有用的内容/root/xorg.conf.new是

非常感谢所有的帮助。

好的。看来我的戴尔外接显示器只能与 NVIDIA 显卡配合使用，而我的内置笔记本电脑显示器则只能在没有 NVIDIA 显卡的情况下工作。

我不确定是什么解决了这个问题。但我做了以下三件事，现在问题解决了。

首先，我的驱动程序似乎amdgpu被列入了黑名单，因此我需要按如下方式将其取消列入黑名单

sudo rm /etc/modprobe.d/blacklist-amdgpu.conf

然后我需要确保我正在使用 NVIDIA 卡：

sudo prime-select on-demand

然后我还安装了 nvidia cuda 工具包：

sudo apt install nvidia-cuda-toolkit

（我不知道为什么，也不知道是否有必要）。

/root/xorg.conf.new似乎没有变化，但是的输出sudo lshw -C display不再存在UNCLAIMED：

其他可能需要的事情包括：

  1. 执行下列操作约五十万次：
sudo apt purge 'nvidia*' 
sudo ubuntu-drivers autoinstall

编辑/lib/modprobe.d/nvidia-kms.conf 为options nvidia-drm modeset=0（而不是1）在执行之后sudo prime-select nvidia/intel/on-demand

3）

安装 amdgpu 驱动程序并将其添加到 /etc/modules或 echo radeon > /etc/modulesecho amdgpu > /etc/modules
