Xserver 偵測到我的外接顯示器，但未偵測到我的整合式筆記型電腦顯示器

我有一台 lenovo Legion 5，運行 ubuntu 22.04（我在 Ubuntu 20.04 上也遇到了同樣的問題，希望升級到 22.04 可以解決問題，但沒有解決）。 2 個外部顯示器和筆記型電腦的螢幕。

與侏儒。

當我啟動電腦時，外部顯示器處於非活動狀態，直到啟動到達gnome 登入（即直到X 伺服器），然後筆記型電腦顯示器保持卡住狀態，登入畫面顯示「按ctrl+c 取消正在進行的所有檔案系統檢查”並且檢測到外部顯示器並顯示 gnome。

如果我按 ctrl+alt+F3 取得終端，它會出現在我的筆記型電腦螢幕上，當我使用 ctrl+alt+F1 返回 X 伺服器時，它們會出現在外部顯示器上。

我有一個 amd 和一個 nvida 顯示卡/gpu：

sudo lshw -C display 給出

有趣的是，當我這樣做時，sudo X -configure 我得到

我沒有/etc/X11/xorg.conf文件。有趣的是，如果我建立一個/etc/X11/xorg.conf包含以下內容的檔案：

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

然後，不再檢測到外部顯示器，但筆記型電腦螢幕可以工作並被 xserver 檢測到。

我不知何故感覺到外部顯示器需要 nvidia 驅動程式才能工作，而筆記型電腦螢幕需要非 nvidia 驅動程式才能工作，但我不知道如何實現這一點。

也可能有用的內容/root/xorg.conf.new是

非常感謝所有幫助。

答案1

好的。因此，我的戴爾外接顯示器似乎只能使用 NVIDIA 顯示卡，但我的內建筆記型電腦顯示器只能在沒有 NVIDIA 顯示卡的情況下使用。

我不確定是什麼解決了這個問題。但我做了以下三件事，現在問題已經解決了。

首先，我的驅動程式似乎amdgpu被列入了黑名單，所以我需要將它們取消黑名單，如下所示

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

然後我需要確保我使用的是 NVIDIA 卡：

sudo prime-select on-demand

然後我還安裝了nvidia cuda工具包：

sudo apt install nvidia-cuda-toolkit

（我不知道為什麼，也不知道是否有必要）。

/root/xorg.conf.new看起來沒有變化，但輸出sudo lshw -C display不再有UNCLAIMED：

其他可能需要的事情包括：

  1. 執行以下約 50 萬次：
sudo apt purge 'nvidia*' 
sudo ubuntu-drivers autoinstall

完成後編輯/lib/modprobe.d/nvidia-kms.conf 為options nvidia-drm modeset=0（而非）1sudo prime-select nvidia/intel/on-demand

3）

安裝 amdgpu 驅動程式並將它們新增/etc/modules為 echo radeon > /etc/modules或 echo amdgpu > /etc/modules
