The trick is to load nvidia card in to the device without module nvidia, because nsight don't need this module to debug. And I don't need nvidia module as a display.
Here is what I did:
I add the file named nvidia_cuda into /etc/init.d and make it executive by chmod +X
This is given by nvidia, but I commented the line /sbin/modprobe nvidia
# /sbin/modprobe nvidia
if [ "$?" -eq 0 ]; then
# Count the number of NVIDIA controllers found.
NVDEVS=`lspci | grep -i NVIDIA`
N3D=`echo "$NVDEVS" | grep "3D controller" | wc -l`
NVGA=`echo "$NVDEVS" | grep "VGA compatible controller" | wc -l`
N=`expr $N3D + $NVGA - 1`
for i in `seq 0 $N`; do
mknod -m 666 /dev/nvidia$i c 195 $i
mknod -m 666 /dev/nvidiactl c 195 255
This file is from
2.5.2. Runfile Installation, Step 6.
But first you need to verify that you have both cards as pci device. I enabled intel multi-display in BIOS to get this.
$ lspci | grep VGA
