It certainly makes sense to simply set up things when the nvidia module
is loaded, although I plan to do it with a udev rule. This will make
nvidia-modprobe redundant on the desktop (i.e. where X is started by
default).
On the server (and on the desktop with Mir), however, X is not started,
and
Thanks for the update! Unassigning and unsubscribing the Ubuntu Security

I've tried installing the NVIDIA drivers from the SUSE repository not
the NVIDIA website in SLED 12.
nvidia-modprobe is installed, but without setuid being set:
~> which nvidia-modprobe
/usr/bin/nvidia-modprobe
~> ls -l /usr/bin/nvidia-modprobe
-rwxr-xr-x 1 root root 25432 Sep 3 10:57
They have the following in /etc/modeprobe.d/50-nvidia.conf:
options nvidia NVreg_DeviceFileUID=0 NVreg_DeviceFileGID=33
NVreg_DeviceFileMode=0660
install nvidia PATH=$PATH:/bin:/usr/bin; /sbin/modprobe --ignore-install
nvidia; /sbin/modprobe nvidia_uvm; test -c /dev/nvidia-uvm || mknod -m 660
Graham, thanks for doing the legwork to confirm that a better solution
is possible.
Alberto, thanks for making the better solution a reality.
Good work all around :)

I can certainly have a look what SUSE do.

Graham, thanks for investigating and reporting back. If you're up for
some legwork, I'm curious what SUSE and Red Hat do here; I don't expect
them to want to use a setuid binary executable for this either and I
wonder if they've got the module loading done differently or better.
Thanks

Alberto has already written udev rules, and they work, however, as far I
can tell, they still require the user to 'sudo modprobe nvidia_uvm'
before running any OpenCL or CUDA applications, or manually add
nvidia_uvm to /etc/modules.
So the question is, do we want to try to load nvidia_uvm and
Just for reference, the nvidia_uvm module does not seem to be needed for normal
desktop and gaming use.
With nvidia-modprobe installed, I opened Steam and the game Portal 2.
Afterwards, nvidia_uvm had not been loaded, and /dev/nvidia-uvm had not been
created.

nvidia-modprobe creates the /dev/nvidia-uvm device node and loads the
nvidia_uvm module for a normal user, on demand.
Using clinfo as an example since it is in the archive, small, and wasn't
compiled against anything Nvidia (it is built against ocl-icd-
libopencl1). See LP: #146 for the

I'm surprised /etc/modules and udev rules aren't sufficient. Why don't
the standard mechanisms for loading modules and creating device nodes
work for nvidia drivers?
Thanks
