| ====External Displays====
| |
|
| |
| In the event that your dedicated GPU has display outputs inaccessible to the internal GPU you need to configure Xorg Displays and set output providers using xrandr.
| |
|
| |
| An example Xorg configuration is below:
| |
|
| |
| {{file|/etc/nixos/configuration.nix|nix|<nowiki>
| |
| {
| |
| services.xserver.config = ''
| |
| Section "ServerLayout"
| |
| Identifier "layout"
| |
| Screen 0 "dGPU"
| |
| Inactive "iGPU"
| |
| EndSection
| |
|
| |
| Section "Device"
| |
| Identifier "iGPU"
| |
| Driver "modesetting"
| |
| BusID "PCI:0:2:0"
| |
| EndSection
| |
|
| |
| Section "Device"
| |
| Identifier "dGPU"
| |
| Driver "nvidia"
| |
| BusID "PCI:1:0:0"
| |
| EndSection
| |
|
| |
| Section "Screen"
| |
| Identifier "dGPU"
| |
| Device "dGPU"
| |
| Option "AllowEmptyInitialConfiguration" "Yes"
| |
| #Option "UseDisplayDevice" "none"
| |
| EndSection
| |
|
| |
| Section "Screen"
| |
| Identifier "iGPU"
| |
| Device "iGPU"
| |
| EndSection
| |
| '';
| |
| }</nowiki>}}
| |
|
| |
| To configure the output sources, first list the providers:
| |
|
| |
| <nowiki>
| |
| xrandr --listproviders
| |
|
| |
| Providers: number : 2
| |
| Provider 0: id: 0x1b8 cap: 0x1, Source Output crtcs: 4 outputs: 3 associated providers: 0 name:NVIDIA-0
| |
| Provider 1: id: 0x202 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 3 outputs: 0 associated providers: 1 name:modesetting
| |
| </nowiki>
| |
|
| |
| You should see two providers, one for the external GPU and one for the internal GPU.
| |
|
| |
| Then run xrandr to set:
| |
|
| |
| <nowiki>xrandr --setprovideroutputsource 1 0</nowiki>
| |
