I'm trying to install CUDA 10.1 on Ubuntu 18.04 using guide from In step 7.2.1 Install Persistence Daemon, when I execute command

/usr/bin/nvidia-persistenced --verbose

I got an error:

$ /usr/bin/nvidia-persistenced --verbose nvidia-persistenced failed to initialize. Check syslog for more details.

Log from the /var/log/syslog file:

May 27 19:49:42 Azurite nvidia-persistenced: Verbose syslog connection opened
May 27 19:49:42 Azurite nvidia-persistenced: Directory /var/run/nvidia-persistenced will not be removed on exit

May 27 19:49:42 Azurite nvidia-persistenced: Shutdown (6802)

Is there something wrong with my CUDA Toolkit installation? Thank you. In logs app:

Sender: nvidia-persiste
Message: Failed to lock PID file: Resource temporarily unavailable

When I run with sudo

I've just checked using htop and there's one running with PID 1304 and Command /usr/bin/nvidia-persistenced --user nvidia-persistenced --no-persistence-mode --verbose. Guess everything is OK, thank you.
