I've been thinking the same thing since my last bout with the
drivers. I don't know what's happening - maybe the hook is there but
it's not working properly, or maybe the package maintainers is not
aware of this issue (which I think is unlikely). 

I think the hook is there, somewhere. I've recently upgraded
from 4.15 to 4.16 and everything worked out fine, and I didn't need to
reinstall the drivers nor build any kernel module. It might be a
version-related issue.

Checking Debian's bug tracker I've found a bug that seems to be
related to what happened to us, from 2014 (last updated in 2015), and
it's still flagged as outstanding.

We need some tests to be sure. I have an extra partition that I
can use for testing, but it might take some time.

I don’t think so, as the experiment matrix I tried above involved rebuilding 
the module using the correct headers every time.

Updating sources to buster and pulling in kernel-image, kernel-headers, then 
restarting to 4.16 to recovery mode, uninstalling nvidia-driver and then 
reinstalling the nvidia-driver package seems to have worked…. However, this 
cannot be the orthodox approach to solve this…..

GTX 560 Ti, which is Fermi, which is indeed old — wikipedia says it’s going to 
legacy after 390 — is that where I may be getting in trouble?  Should I try 
nvidia-legacy in debian?

Hello,

I had a similar problem when I upgraded from Stretch (4.9) to
Buster (4.15). The nvidia driver stopped working but after reinstalling
it started to work again, supposedly because it needed to rebuild the
kernel module with headers from the new kernel. Maybe you're having a
similar issue?

Which nvidia card are you using?

backports on kernel 4.15 and nvidia-driver 390 crashes x

[Boyan Penkov]

Hello,

I have upgraded to the current stretch backports nvidia-driver, and this 
crashes on the current stretch backports kernel.  Have folks seen this 
combination work?

I see the following:

kernel — nvidia — status
4.15 — 390 — fail
4.15 — 370 — untested
4.9 — 390 — fail
4.9 — 375 — success

Anything I can do to help debug? What’s annoying is that the fails on 390 print 
a blank screen with no X cursor and a prompt to log out, so I don’t know where 
to look for logs or traces….

Cheers!
