在 G4ad 上設定雙 4K 顯示器 - Amazon Elastic Compute Cloud

在 G4ad 上設定雙 4K 顯示器

啟動 G4ad 執行個體

  1. 連線到 Linux 執行個體以獲取您希望用於雙 4K (2x4k) 的目標 GPU PCI 匯流排地址：

    lspci -vv | grep -i amd

    您將會得到類似下列的輸出：

    00:1e.0 Display controller: Advanced Micro Devices, Inc. [*AMD*/ATI] Device 7362 (rev c3)
Subsystem: Advanced Micro Devices, Inc. [AMD/ATI] Device 0a34

  2. 注意上述輸出中 PCI 匯流排地址為 00:1e.0。建立名為 /etc/modprobe.d/amdgpu.conf 的檔案並新增：

    options amdgpu virtual_display=0000:00:1e.0,2

  3. 請依照此處的指示，在 Linux 上安裝 AMD 驅動程式。如果您已經安裝了 AMD GPU 驅動程式，則需要透過 DKMS 重建 amdgpu 核心模組。

  4. 使用下面的 xorg.conf 檔案定義雙 (2x4k) 畫面拓撲，並將檔案儲存在 /etc/X11/xorg.conf:

    ~$ cat /etc/X11/xorg.conf

  5. 請依照「設定互動式桌面」中的指示來設定 DCV。

  6. DCV 設定完成後，請重新啟動。

  7. 確認驅動程式可正常運作：

     dmesg | grep amdgpu

    回應應如下所示：

    Initialized amdgpu

  8. 您應該會在 DISPLAY=:0 xrandr -q 輸出中看到您已連接 2 個虛擬顯示器：
