I have ubuntu 14.04 installed. My Graphics Card is Nvidia GeForce GT755M SLI
Whenever i enable SLI or MultiGPU the screen goes black after bootlogo. The bootlogo appears, when the bootload is finished screen goes black and i cant do anything. I have to shutdown the computer with the power button.
I tried to enable SLI in two different ways.
- By editing the xorg file in /etc/X11/xorg.conf
Identifier "Screen0" Device "Device0" Monitor "Monitor0" DefaultDepth 24 Option "Stereo" "0" Option "metamodes" "nvidia-auto-select +0+0" Option "SLI" "on" Option "MultiGPU" "off" Option "BaseMosaic" "off" SubSection "Display" Depth 24 EndSubSection
I also tried turning the MultiGPU but still got blackscreen Then i turned both on and still got blackscreen.
- I tried to enable it by running the following commands in terminal
sudo nvidia-xconfig --sli=On
I still experienced blackscreen
I also enabled MultiGPU by using the following command
sudo nvidia-xconfig --MultiGPU=on
still did not help
Please answer if you have any solutions.
