I have an issue where enabling SLI causes me to have a black screen on startup
When I check the logs I notice the below:
[ 19.482] (II) NVIDIA(GPU-0): NVIDIA SLI enabled.
[ 19.483] (EE) NVIDIA(GPU-0): Failed to select a display subsystem.
[ 19.483] (EE) NVIDIA(GPU-0): Only one GPU will be used for this X screen.
[ 19.483] (EE) NVIDIA(GPU-0): The NVIDIA graphics device PCI:1:0:0 is part of an active SLI
[ 19.483] (EE) NVIDIA(GPU-0): configuration and is currently unavailable for single GPU
[ 19.483] (EE) NVIDIA(GPU-0): rendering. Please see Chapter 30: Configuring SLI and
[ 19.483] (EE) NVIDIA(GPU-0): Multi-GPU FrameRendering in the README for troubleshooting
[ 19.483] (EE) NVIDIA(GPU-0): information.
[ 19.483] (EE) *** Aborting ***
[ 19.483] (EE) NVIDIA(0): Failing initialization of X screen
Not sure why it mentions in that log it is unavailable for single GPU rendering and can’t seem to find where that is set.
The settings for my xorg.conf display are as below:
Section "Monitor"
Identifier "Monitor0"
VendorName "Unknown"
ModelName "Unknown"
Option "DPMS"
EndSection
Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BusID "PCI:1:0:0"
EndSection
Section "Device"
Identifier "Device1"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BusID "PCI:8:0:0"
EndSection
Section "Screen"
Identifier "Screen0"
Device "Device0"
Monitor "Monitor0"
DefaultDepth 24
Option "SLI" "On"
SubSection "Display"
Depth 24
EndSubSection
EndSection
I have tried connecting to all DP/HDMI ports on both cards but not the DVI ports as I do not have the cables so not sure if that would be the issue?
Any help appreciated
