error: “Oh no! Something has gone wrong.”

If the above message suddenly comes up in your screen after CUDA driver installation in RedHat/CentOS/Fedora OS, don’t be panic. This is happened because of xorg-x11-drv-nvidia-gl package, which is part of cuda-drivers dependencies. I got this experience in my laptop that has Intel + NVIDIA GPUs. I guess it’s because the Intel GPU is the primary GPU in my laptop, and for RedHat/CentOS/Fedora there’s no a kind of official Optimus technology, like in Windows.

Workaround Solution:

1. remove xorg-x11-drv-nvidia-gl package: yum remove xorg-x11-drv-nvidia-gl
2. reboot
3. after removing the package, most CUDA samples still can run except those apply CUDA-OpenGL interop.

I have heard and tried Bumblebee, but in my experience it didn’t help to make CUDA-OpenGL interop working.
