I have a 2 GPU system(lets call them gpu1, and gpu2), mainly for deep learning tasks , by default the monitor/display is connected to gpu1, but i want to connect it to gpu2 and cant find how to do it,i tried just “plug and play” but the system wont render anything, i tried with nvidia-settings but cant find there any way to configure, so the question is simple, how can i specify which of my 2 gpus will be the one used for displaying/connectiong monitor?
Use a minimal xorg.conf like
Section "Device" Identifier "nvidia" Driver "nvidia" VendorName "NVIDIA Corporation" BusID "PCI:1:0:0" Option "AllowEmptyInitialConfiguration" EndSection
The BusID option tells the xserver which gpu to use. Look it up by using
Note: lspci displays values in hex, BusID takes decimal values.
