Hello,
Lastly the repository bumblebee X11 has updated the nvidia driver to the version 410.xx. I have upgrade it my driver to this version. Unfortunately, something has happen, I cannot use nvidia-smi any longer. I get this error when I try to run it
NVIDIA-SMI couldn't find libnvidia-ml.so library in your system. Please make sure that the NVIDIA Display Driver is properly installed and present in your system.
Please also try adding directory that contains libnvidia-ml.so to your system PATH.
I also can’t run any program that using cuda 9.1 I get this message “CUDA driver version is insufficient for CUDA runtime version”.
However, I can still run program using optirun and I am sure it’s using nvidia driver because of the output of this “lsmod | grep nvidia”
lsmod | grep nvidia
nvidia_uvm 909312 0
nvidia_drm 45056 3
nvidia_modeset 1044480 3 nvidia_drm
nvidia 16605184 159 nvidia_uvm,nvidia_modeset
ipmi_msghandler 65536 2 ipmi_devintf,nvidia
drm_kms_helper 196608 2 nvidia_drm,i915
drm 471040 19 drm_kms_helper,nvidia_drm,i915
So what do you thing how can I fix the problem of nvidia-smi and cuda. Should I upgrade cuda to the 10.0 version?
Thank you guys.
Note:
I couldn’t find the file libnvidia-ml.so in /usr/lib64/nvidia/
