Unfortunately no.

Looking at sys.log I no longer see the message about the mismatch 
between the kernel and the client. But I do see this:

init: nvidia-prime main process (1138) terminated with status 127 (I 
googled this but found nothing useful)

and this:

Nov  6 21:39:14 Jims-1404 kernel: [   15.146820] nvidia: module license 
'NVIDIA' taints kernel.
Nov  6 21:39:14 Jims-1404 kernel: [   15.146826] Disabling lock 
debugging due to kernel taint
Nov  6 21:39:14 Jims-1404 kernel: [   15.157800] nvidia: module 
verification failed: signature and/or required key missing - tainting kernel

(googling this didn't seem to produce anythin useful)

When I ran your commands above I saw something about extras scroll by 
and reference to a key.  Which log would let me search for that message?

Thanks,  Jim
