xrandr 1.4와 2 개의 비디오 드라이버가있는 듀얼 모니터 -c video *-display

나는 2 개의 다른 비디오 카드 드라이버 (i915 & nvidia)로 듀얼 스크린을 시도하고 있지만 xrandr는 nvidia 공급자만을 나열하고 있습니다. 아치 리눅스를 사용하고 있습니다. xrandr공급자 목록을 얻는 위치를 찾지 못했습니다 .

[x@epoch ~]$ xrandr --listproviders

i915를 볼 수없는 이유가 있습니까?

/etc/X11/xorg.conf에서 GPU를 다음과 같이 정의해야합니다.

Section "ServerLayout"
    Identifier "layout"
    Screen 0 "nvidia"
    Inactive "intel"
EndSection

Section "Device"
    Identifier "nvidia"
    Driver "nvidia"
    BusID "<BusID for NVIDIA device here>"
EndSection

Section "Screen"
    Identifier "nvidia"
    Device "nvidia"
    # Uncomment this line if your computer has no display devices connected to
    # the NVIDIA GPU.  Leave it commented if you have display devices
    # connected to the NVIDIA GPU that you would like to use.
    #Option "UseDisplayDevice" "none"
EndSection

Section "Device"
    Identifier "intel"
    Driver "modesetting"
EndSection

Section "Screen"
    Identifier "intel"
    Device "intel"
EndSection

다음 명령으로 NVIDIA 이외의 카드를 활성화 할 수 있습니다.

$ xrandr --setprovideroutputsource modesetting NVIDIA-0
$ xrandr --auto

실제로 작동하는지 확인할 수 있습니다. nvidia 문서 페이지의 새 URL은 이제 http://us.download.nvidia.com/XFree86/Linux-x86/319.12/README/randr14.html입니다 (이전 URL은 작동하지 않음).

듀얼 모니터 설정은 각각 GTX1080 및 Intel HD Graphics 4000 (i5 3570) 통합 그래픽입니다.

다음 xorg.conf가 완벽하게 작동했습니다.
