xqms / System configuration
Created October 2, 2014 10:27
Linux configuration for Intel Graphics and NVIDIA CUDA on Lenovo T440p
This is my current system configuration. I use the intel graphics for graphics, and just keep the NVidia card running for CUDA applications. Note that this setup does not give you 3D acceleration on the NVidia card!
Sometimes (only after suspend) I have to use the attached reload_nvidia.sh script because my CUDA applications complain about a "invalid device ordinal".
BIOS version: 1.17
Linux: Ubuntu 14.04 with kernel 3.17.0-031700rc4-generic
kernel cmdline: "acpi_osi=!Windows 2012"
nvidia driver 340 manually installed from the xorg-edgers PPA:
