Bug#996595: nvidia-legacy-390xx-driver: NVIDIA service is not starting with the system

[Andreas Beckmann]

Thanks.

Please also send the output of

update-alternatives --display glx
update-alternatives --display nvidia

Do you know why you have libnvidia-cfg1 (from the current, not the 
legacy driver)installed? That probably stems from the attempt to install 
nvidia-settings for the current driver.
(You also have libnvidia-legacy-390xx-cfg1 installed.)

If you uninstall libnvidia-cfg1 everything should be back to normal again.
