我在我的笔记本电脑上安装了 Arch,但我不认为这个问题是 Arch 特有的。目前唯一的问题是未检测到连接到 hdmi 端口的显示器。例如,从 gnome 控制中心运行显示小程序,然后“检测”仅检测笔记本电脑显示屏,即使有第二个显示器通过 HDMI 端口连接到笔记本电脑。我怀疑问题是 xrandr 没有检测到连接到 HDMI 端口的显示器。我怎样才能解决这个问题?

答案1
我想到了;我生成的xorg.conf
nvidia 模块路径错误并且没有指定busid。为了找出我使用的busid:
$ lspci -v
01:00.0 VGA compatible controller: nVidia Corporation GT200 [GeForce GTX 260] (rev a1)
然后我进行了编辑xorg.conf
,使其具有与此类似的部分:
Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BusID "PCI:01:00:0"
Option "NoLogo" "true"
Option "UseEDID" "true"
Option "ConnectedMonitor" "DFP"
EndSection
Section "Files"
ModulePath "/usr/lib/<path to nvidia driver>"
ModulePath "/usr/lib/xorg/modules"
