I have a HP workstation with two cards - QuadroK2200 and TeslaK40.
I have Ubuntu 14.04 running.
I installed cuda7 by downloading from Nvidia download site and then follwing instructions.
But after i reboot, and i try to login, the system gets stuck.
After reading some additional posts, I also created the file for blacklisting nouveau.
If it do Ctrl+Alt+F1, I see the error - could not insert nvidia 346.
I even tried NVidia-xconfig to create a config file for Xserver.
But none of these solved the problem
How do i get the system to work with Cuda
