Brand new poster here, so I’m sure that this will be a little short on the information needed to fully diagnose and fix the problem.
I’ve tried both the runfile and the .deb installation methods outlined in the cuda instruction manual, and nothing seems to work. I’ve been attempting to install CUDA 8.0 onto ubuntu 16.04 with a GTX980 graphics card.
In the best case, everything seems like it installed, I run deviceQuery and…syntax error, “)” not expected (as I recall, but the system is down right now). Other issues I’ve encountered include a login-screen loop where I can’t get past the login screen (something about not fully purging nvidia drivers caused that, I think), an issue where the installer couldn’t find the kernel headers (yes, I’d updated them, yes, I checked. The solution was to downgrade Ubuntu using sudo apt-get purge && sudo apt-get purge – both of which seem dangerous things to do.)
Steps taken include (skipping the checking if ubuntu and the gfx card are supported):
- clean install of ubuntu + sudo apt-get update && sudo apt-get upgrade
- download the files
- check the md5sum
- reboot into mode 3
- follow the instructions to purge nvidia-, nvidia-cuda, and blacklist nouveau
- sudo sh <runfile_name>
- yes to drivers, openGL libraries (doesn’t make a difference-- same results either way), toolkit, samples, etc.
- default paths
- wait for install to finish
9a) keep waiting
- run the export statements
- make sure the install was successful with nvcc -V and nvidia-smi
- make and attempt to run the samples
I’m about at my wits’ end, here. By everything I’ve done, it seems like this /should/ be working. Can anyone (NVIDIA devs, looking at you in particular) help, please? Feel free to be (extremely) detailed-- I’m inexperienced enough it’s not possible to be too much so.
