(I'm aware there are several questions with a similar title but they either don't have answers, are very old or don't apply to my situation.)
I'm using Ubuntu 18.04.2, my GPU is a GeForce 840M and the driver version is nvidia-driver-430 (installed from the Softwares and updates panel)
So I can't seem to use the nvidia gpu anymore. I have no idea what caused this.
gives the following output:
ERROR: NVIDIA driver is not loaded ERROR: Unable to load info from any available system
It does open an Nvidia panel but without the usual settings and just the two PRIME profiles (Nvidia performance mode and intel power saving mode ).
gives the following 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've tried a few things like purging and reinstalling the driver or using an older one , with no luck. I've also tried downloading and running the .run driver from the nvidia website but it failed to install.
I'm looking for advice on what to try next to have it working again. Thanks for your help :)
