我最近安装了 Manjaro Plasma。我有华硕和 Nvidia GTX 1650 Ti。
这是我的lspci设置：
01:00.0 VGA compatible controller: NVIDIA Corporation Device 1f91 (rev a1)
Subsystem: ASUSTeK Computer Inc. Device 109f
Kernel driver in use: nvidia
Kernel modules: nouveau, nvidia_drm, nvidia
05:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Picasso (rev c2)
Subsystem: ASUSTeK Computer Inc. Picasso
Kernel driver in use: amdgpu
Kernel modules: amdgpu
我创建并更改了 xorg.conf 文件，使其看起来像这样：
# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings: version 440.59

我厌倦了在 laprop 屏幕上添加 Option Primary true，但它没有改变任何东西，所以我想这条线是 unecesarry。另外，默认的 xorg.conf 文件包含除 Screen1、Monitor1 和 Device 1 之外的所有内容，而当时只能使用外部监视器，所以我添加了这些 Screen1、Monitor1 和 Device1，这样笔记本电脑的屏幕也可以工作。
现在，当外接显示器打开时，一切工作正常。另外，当我登录并禁用第二个监视器时。但问题是登录屏幕显示在外部显示器上，而笔记本电脑显示屏仅在登录后显示。所以当我没有连接外部显示器时。我无法登录linux。
