I can't install CUDA 8 Toolkit on Ubuntu 14.04. I get this error:

    Do you want to install the OpenGL libraries?
    (y)es/(n)o/(q)uit [ default is yes ]: yes

    Do you want to run nvidia-xconfig?
    This will update the system X configuration file so that the NVIDIA X driver
    is used. The pre-existing X configuration file will be backed up.
    This option should not be used on systems that require a custom
    X configuration, such as systems with multiple GPU vendors.

Thsi are the log files: http://pastebin.com/KLAZ4b5g and http://pastebin.com/wRJq8t51 I also had installed this Nvidia driver for Tesla K40c GPU prior to installing the CUDA 8 Toolkit.

NVIDIA-Linux-x86_64-361.93.02.run

Any guidance as what to fix?

Solution

Firstly pay heed to the warning:

This option should not be used on systems that require a custom
X configuration, such as systems with multiple GPU vendors.

On my laptop I have an Intel HD4000 GPU and Nvidia GT650M so it could be a warning for me. Be sure of what you are installing!

As far as the error message, you have to run the installation through the console when X-Server isn't running. Reboot your machine. At the normal Ubuntu gooey (GUI) login prompt press Ctrl+Alt+F1 and the console (text based) login will appear. Enter your user ID and password.

Then type:

sudo ./cuda_8.0.44_linux.run

Then reboot by typing:

sudo reboot

Login normally at the regular GUI prompt.

If there still is a problem post comment below.

Always install the Nvidia drivers though apt-get. Never any other way, unless you know exactly what you're doing.

Nvidia website has suggested to install it this way rather than apt-get!!!

[Mona Jalal]

and yes, I know what I am exactly doing

[You'reAGitForNotUsingGit]

Errrrmmm... well... ask just about anyone here, and they'll you to only install via apt-get.

You think this answer might help? askubuntu.com/a/818510/231142

I can't do this because i am trying to do this at a remote sshd machined and when i press those buttons my own ubuntu machine x server exits. Solution?

@MonaJalal As painful as it sounds, call someone at the remote machine location and ask them to type in the commands. Maybe e-mail them the commands and have them print them out.
