Hello,

I followed the instructions in the Readme file, compiled the nvtop from source and have the RPM Fusion Driver installed. nvidia-smi outputs:

When I try to run nvtop the output is:

No GPU to monitor.

I tried following the similar issue description, but the libraries seem linked:

ldconfig -p | grep libnvidia-ml
    libnvidia-ml.so.1 (libc6,x86-64) => /lib64/libnvidia-ml.so.1
    libnvidia-ml.so.1 (libc6) => /lib/libnvidia-ml.so.1
    libnvidia-ml.so (libc6,x86-64) => /lib64/libnvidia-ml.so

Nvtop works with the nvidia driver downloaded from the website however... Is there any way to make it run with RPM Fusion driver? (there are issues I have with the driver from nvidia website so I need to stay with RPM Fusion version)

Turned out it was a library mismatch that resulted from the driver update. The situation was as follows:

lrwxrwxrwx. 1 root root      22 Nov  2 16:41 libnvidia-ml.so.1 -> libnvidia-ml.so.495.44
lrwxrwxrwx. 1 root root      25 Oct 12 13:21 libnvidia-ml.so -> libnvidia-ml.so.495.29.05
-rwxr-xr-x. 1 root root 1840344 Sep 30 17:50 libnvidia-ml.so.495.29.05
-rwxr-xr-x. 1 root root 1840344 Oct 22 08:05 libnvidia-ml.so.495.44

so nvtop was confused trying to load libnvidia-ml.so which pointed to old dll. Once the link was updated to proper location the issue disappeared.
