I wanted to use CUDA for computing acceleration. I launched a g2.2xlarge instance (with NVIDIA GRID K520) on AWS EC2. I installed the Ubuntu 14.04 (hvm) AMI and updated to the latest.
As CUDA 6.0 doesn’t provide an installer for Ubuntu 14.04, I downloaded CUDA 6.5 RC and installed it following the instructions. Everything went OK.
I rebooted. For whatever I try to do afterwards I always get this error
modprobe: ERROR: could not insert ‘nvidia_340’: Unknown symbol in module, or unknown parameter (see dmesg)
There’s nothing like /dev/nvidia*. Apparently the module is never started by the Linux kernel.
Did I miss anything? Do I need to do sudo apt-get install ubuntu-desktop beforehand? I thought CUDA would install all the packages it depends on, e.g. xorg-server, etc?
Thanks in advance.
