nvidia-367 with GeForce GTX 460 prevents boot

[Andrew J. Caines]

Up-to-date Ubuntu 16.04.1 LTS (4.4.0-45-generic #66-Ubuntu SMP Wed Oct
19 14:12:37 UTC 2016) booted fine with nvidia-361 and associated
packages on PC with GeForce GTX 460.

After updating yesterday including to nvidia-367 the system failed to
boot, Plymouth stopping with the post boot script message which precedes
starting the GUI booting the kernel with "verbose splash" - possibly
"Running /scripts/local-top ..." .

In maintenance mode, "journalctl -xb" gave no hint of video related or
relevant problems.

Removing all nvidia packages results in the system booting to a desktop
using Gallium. A subsequent clean install of nvidia-367 and related
packages returns the system to the unbootable state.


Further details and answers provided on request, subject to available
logs and memory. You can also find me as AJ_Z0 in #ubuntu on FreeNode.
