With the nvidia-352 driver in 14.04, there no longer seems to be an uvm package, and the nvidia-modprobe package is at version 340.21.
In the past I've added "nvidia-uvm" to /etc/modules, and the following from here [ http://developer.download.nvidia.com/compute/cuda/6_5/rel/docs/CUDA_Getting_Started_Linux.pdf ] to /etc/rc.local to get CUDA working in Blender: /sbin/modprobe nvidia-uvm if [ "$?" -eq 0 ]; then # Find out the major device number used by the nvidia-uvm driver D=`grep nvidia-uvm /proc/devices | awk '{print $1}'` mknod -m 666 /dev/nvidia-uvm c $D 0 else exit 1 fi With nvidia-modprobe installed, "lsmod | grep nvi" does list nvidia-uvm, but there is not /dev/nvidia-uvm device created. Running the above script snippet creates /dev/nvidia-uvm, but CUDA is still not working in Blender. It would be great if CUDA worked out of the box, either when you install the nvidia-352 driver, or at least when you install libcuda1-352. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-graphics-drivers-331-updates in Ubuntu. https://bugs.launchpad.net/bugs/1361207 Title: nvidia-graphics-drivers-* should recommend nvidia-modprobe Status in nvidia-graphics-drivers-331 package in Ubuntu: Confirmed Status in nvidia-graphics-drivers-331-updates package in Ubuntu: Confirmed Status in nvidia-graphics-drivers-340 package in Ubuntu: Confirmed Status in nvidia-graphics-drivers-340-updates package in Ubuntu: Confirmed Status in nvidia-graphics-drivers-346 package in Ubuntu: Confirmed Status in nvidia-graphics-drivers-346-updates package in Ubuntu: Confirmed Bug description: nvidia-modprobe allows non-root users to load NVIDIA kernel modules and it creates the respective device entries. This is important for CUDA users as they would otherwise have to run a workaround script to load the kernel modules and create the device entries. This is documented here: http://developer.download.nvidia.com/compute/cuda/6_5/rel/docs/CUDA_Getting_Started_Linux.pdf -> 4.8 Verification Because of this newer nvidia-graphics-drivers packages (331 and newer) should at least recommend nvidia-modprobe. Furthermore the nvidia- modprobe is not available from xorg-edgers. Utopic includes an nvidia- modprobe package though.
