CUDA 6.5 samples works fine as standalone.
On remote debugging through nsight the window shows up but no graphics are shown.
I did try:
sudo echo N > /sys/kernel/debug/gk20a.0/timeouts_enabled
It didn’t help.
Background: I use nsight eclipse on Ubuntu 14.04 amd64 on a laptop that has no nvidia GPU, and I remote debug through nsight on the Jetson TK1 that runs toolkit 6.5.
