nvidia-384 driver causes immediate suspension upon login & subsequent system hang with blank screen

[Dan]

OS: Ubuntu Artful Aardvark (development branch), Release: 17.10

Package: nvidia-384

Laptop model: Lenovo Z50

Graphics: Gforce 840M

Expected behaviour: To be able to login.

Actual behaviour:

After installing the Nvidia 384.90 driver from the nvidia-384 package and rebooting, I am unable to login to a graphical session.

The system boots without issue and I enter credentials to login. After clicking the button to login (or hitting Enter), the system immediately suspends.

Hitting any key on the keyboard resumes, to a blank (black) screen. The system then hangs entirely unresponsive. I am unable even to drop to terminal.

Removing the above nvidia package immediately resolves the issue and I am able to login to a graphic session as normal.

During install observed lz error during unpacking files.

bug manifests as fail during logon which flips back to the signon screen.

Fast path to recovery was power down, popping out the nvidia card and installing an ancient AMD card which automatically restored nouveau allowing purge of broken packages using synaptic pkg manager .

Reverting back to the nvidia-340 pack restored function after repopulating the nvidia card.
