Sounds like you messed up your video drivers. Try ssh'ing to the machine and see if it's there. Or hit Ctrl-Alt-F2 to switch to VT2 and login at a command line. Look at the logs in /var/log for clues about what's wrong.

Thank you
did that.
and removed nvidia drivers form xorg.
its working now
will try to install nvidia cuda without the drivers packed into cuda toolkit.

after re installation of CUDA8 I faced the issue again. How do i stop installing drivers from CUDA?

Having this exact same problem with supermicro dual-xeon server with 4x Titan-X 12GB Pascal cards and 1 onboard Matrox VGA.

I followed the nvidia cuda 8 guide, all 9 pages, to get a Centos 7 that boots to "oh no, something went wrong" followed by a black screen.
I also followed the much more involved EPEL/elrepo/bumblebee guide that gets hashed out in this post:
viewtopic.php?f=49&t=61162

this seemed to get some nvidia graphics card drivers working... I think?
at least the OS continued rebooting.

but trying to follow up these guides with the Cuda 8 installer complains that the drivers are not recent enough and must be updated, followed by a non-booting OS again.

Would really appreciate a nub guide from anyone who has successfully achieved CUDA 8 working with Centos 7. Please don't assume I'll know obvious linux shorthand. I come from the other world, where you just click the next button over and over and start working on the actual problem, not the problems leading up to the problem.

Has anyone found a solution to this? I'm having the same problem unfortunately, with CUDA 8, Centos 7.3, NVIDIA driver 375.51

Thank you

the issue i had was it did not boot to graphical interface i got it fixed by changing xorg.conf file at /etc/X11/xorg.conf.
removing the existing xorg.conf file, or adding the contents of /etc/X11/xorg.conf.d/xx-nvidia.conf to the xorg.conf file.

Deleting the Xorg.conf file worked perfectly. Thanks so much!
