[Solved] modprobe can't load nvidia-uvm

niharsarangi · 2016-05-15 18:39:36

I have installed the latest nvidia and cuda drivers through pacman.
I have verified that the nvidia module is being loaded properly. And I can use it to run CUDA applications.
However, some applications that require nvidia-uvm are failing because modprobe can't find nvidia-uvm. I am getting this error :

modprobe: FATAL: Module nvidia-uvm not found.

I checked in the location and nvidia-uvm is not inside the /lib/modules/$(uname) directory but there is a file called nvidia-uvm.ko.gz in a directory called extra-modules inside it.

How can I load nvidia-uvm? Is it required to remove nvidia drivers and install nvidia-dkms instead?

Have you installed opencl-nvidia ?

Yes. opencl-nvidia is up to date.

Please post the output of the following:

$ uname -a
$ modinfo nvidia-uvm
$ pacman -Qs nvidia

I am not sure what I did. But after a full system upgrade and reinstalling the nvidia drivers it seems to work. The logs are as follows:

If you have solved the problem, please mark your thread as solved by editing the first post and amending the topic title.

Everything looks fine in that output, but presumably it is from after you fixed the problem.
