我目前在我的筆記本 Lenovo Gaming 15AH05 中使用 Ubuntu 22.04，沒有額外的顯示器。最近我安裝了 Nvidia 驅動程序，當我運行命令“nvidia-smi”時，輸出如下：
+-----------------------------------------------------------------------------+

我還使用命令“nvidia-xconfig”創建了一個非常預設的 xorg.conf 文件，創建了以下結果：
# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig: version 525.85.05

這是命令「lspci |」的結果grep VGA'：
01:00.0 VGA compatible controller: NVIDIA Corporation TU117M [GeForce GTX 1650 Ti Mobile] (rev a1)
05:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Renoir (rev c6)
現在，當我訪問設定 > 詳細資訊 > 圖形它說：“NVIDIA Corporation TU117M [GeForce GTX 1650 Ti Mobile] / RENOIR（雷諾阿，LLVM 15.0.6，DRM 3.47，5.19.0-35-generic）”
所以我可以看出它正在被識別，但是當我訪問視頻遊戲（在本例中為異星工廠）並將精靈圖形質量修改為“高”時，它會顯示“我們檢測到您的顯示卡只有512mb內存......” （即使當我嘗試運行它時右鍵>使用專用顯示卡運行）
所以我想知道是否有一種方法可以正確設定 xorg.conf 檔案以使我的專用顯示卡成為系統的預設顯示卡，或者也許有一種更好的方法來解決這種情況，從而作為更好的解決方案。
