I have updated the drivers and now when I try to login after having suspended the session I get a black screen and I cannot do anything but forcing the rebooting.
Also when I type nvidia-smi I get:
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 have tried already all proposed solutions in this forum and nothing worked…
