Last time I tried using
nvidia-smi it worked fine in my Ubuntu 16.04 machine with a Pascal Titan X.
After a month or so of not using the machine, I booted up and acceleration no longer works. I tried to run
nvidia-smi and I get this error:
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
I tried re-installing the latest version of the driver with:
sudo ./NVIDIA-Linux-x86_64-390.42.run -no-drm
nvidia-smi reports the same error. Running
lsmod | grep nvidia shows nothing.
I tried installing the driver this way:
sudo apt-get purge nvidia* sudo add-apt-repository ppa:graphics-drivers sudo apt-get update sudo apt-get install nvidia-384
Then restarted - still nothing for
lsmod | grep nvidia and same error for
/var/log/syslog, I see this message:
nvidia: version magic '4.4.0-116-generic SMP mod_unload modversions ' should be '4.4.0-116-generic SMP mod_unload modversions retpoline '
How can I trouble-shoot and get acceleration working again?
