Then please uninstall bbswitch+bumblebee.
I did, and right after that I got a different output from nvidia-smi
. Look:
# nvidia-smi

But after a restart that output is gone again:
# nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
And the output of glxinfo -B
has never changed at all.
Please create a new nvidia-bug-report.log
uninstalling bumblebee un-blacklisted nouveau. Please blacklist it using kernel parameter
nouveau.modeset=0
I added it and then ubuntu got stuck in the loading screen forever. I had to remove it again.
