Ubuntu 14.04 hangs after installing Cuda

I have installed Cuda on my machine and have successfully run the deviceQuery example by following the instructions in this link: http://docs.nvidia.com/cuda/cuda-getting-started-guide-for-linux/#axzz3m5Fj01dr.

After restarting the machine, it froze on the Ubuntu booting screen. I had uninstalled cuda in recovery mode in order to get my system working again. However, I need to reinstall Cuda and am not sure how to proceed with it in order to avoid the same problem. Feedback on how to solve this would be greatly appreciated.

Running “lshw -c video” gives the following information:

Same problem here. Any success there?

Hello There,

I was facing similar problem on G2 instance (Ubuntu 14.04 , 64 bit, Cuda 7.0) and I could fix this issue by disabling Message Signal Interrupt in nVIDIA configuration.

My nvidia conf file now looks as below.

ubuntu@ip-172-30-4-159:~$cat /etc/modprobe.d/nvidia-installer-disable-nouveau.conf

generated by nvidia-installer

blacklist nouveau
options nouveau modeset=0
options nvidia NVreg_EnableMSI=0

This should help you.
If problem still persists upgrade nVIDIA driver to 352.xx and again make above config changes.
Should work for sure
