The problem seems to be due to uefi secure boot option now checking also the
keys of modules, which the nvidia driver obviously does not provide. Disabling
secure boot solved the problem for me, but completely disabling it just because
there is no signature for the nvidia driver seems to be a really bad option!
Shouldn't there be an option to install signatures for third party drivers,
that are supported (nvidia, virtualbox etc)?
I think this bug rather affects the package 'shim'...

Regression: Kernel Update in 16.04 from last days renders nvidia
driver unusable

Bug description:
I am running Ubuntu 16.04 since at least four months, always with the
nvidia proprietary drivers (installed from the repository). I used
nvidia-361 for a while with no issues (and i need it for steam
gaming). However, an update installed on my machine yesterday breaks
the nvidia drivers. I tried purging the driver, rebooting and
reinstalling and i tried a newer version for the ubuntu-drivers ppa.
Nothing helps: With the nvidia driver installed, i get a low-
resolution login screen, but cannot login due to missing 3d
acceleration. Running on nouveau works fine.
This seems very strange to since everything worked until this
afternoon. Yesterday, i was happily playing games on steam, installed
some updates and now, my graphics are broken.
