Hi! I discovered that in despite of having a SLI capable laptop (2 identical GT8700M GPU's) and having successfully setup this in the past (with Slack 12 & OpenSUSE), I am no longer capable of doing so as there is only 1 GPU's detected by the nvidia-settings application. I do remember that I normally have to add the options MultiGPU SLI both to "ON" to use the SLI feature but not having 2 GPU's wont help...
I added these options to xorg.conf using the xnvidia-settings command but the second GPU is still not detected.
Trying:
Code:
/sbin/lspci | grep -i vga
gives:
Code:
03:00.0 VGA compatible controller: nVidia Corporation G84 [GeForce 8700M GT] (rev a1)
and as you can see, there is no 2nd GPU...
also trying:
gives:

I got these commands from the Nvidia Linux support forum. According to NVidia, this could be caused by a kernel that does not detect the PCI link between the video cards (the SLI link).
I am currently using a generic kernel 2.6.33.4-smp. I use stock slack 13.1 (except the kernel).
I have Nvidia driver 195.36.31 with X server 11.
Anybody know what I need to do to get the second GPU detected? I reverted from Hugesmp to generic because I have been recommended to do so to avoid misc problems (such as fatal errors with NFS shares, etc...) and improved compatibility.
